Toyota Airbag Module Crash Reset & Repair Service — All Toyota Models 1995–2026
Nationwide mail-in service — ship your module to us from anywhere in the United States. Walk-in also available at our Portland, Oregon shop (Karman Auto, 4943 NE 105th Ave, Portland, OR 97220).
Toyota airbag module reset performed by Dan Karman — Toyota SRS specialist since 1999, online since 2006. Full reset process documented on our YouTube channel. Reference updated April 2026.
Quick answer:
Every Toyota SRS airbag module from 1995 through 2026 (Denso part-number family 89170-XXXXX) can be bench-reset after a crash. Karmanauto clears the EEPROM crash record, wipes the Techstream-proof internal lockout byte, and returns your original Center Airbag Sensor Assembly same-day — plug-and-play, no dealer, no Techstream programming required on most models.
Why you need a bench reset, not a new module
After any airbag deployment, your Toyota’s Denso-built Center Airbag Sensor Assembly stores hard crash codes and an internal lockout byte in EEPROM that no Toyota Techstream scan tool can erase. The dealer’s fix is a new VIN-coded module at $800–$1,400, plus Techstream programming labor.
Our bench service reads the original EEPROM, wipes every deployment flag, event-data record, and the lockout byte, and ships the module back the same day. No Techstream, no dealer trip, plug-and-play.
Covers every Toyota SRS control module — Denso 89170-XXXXX part number family, OEM Denso-built across all Toyota models 1995 through 2026. Crash data cleared, hard codes removed, seatbelt pretensioner faults repaired. Same original Center Airbag Sensor Assembly returned, fully functional, programmed to original VIN configuration. After a Toyota is involved in any impact — deployment or not — the SRS (Supplemental Restraint System) Center Airbag Sensor Assembly stores a permanent crash code. That single stored code locks the airbag light on. The module will not clear this code with Techstream, OBD-II, or any generic scan tool. Dealers replace the entire Center Airbag Sensor Assembly for $800 to $1,400 plus VIN-matched programming. We reset and repair the original Toyota SRS module for a fraction of that cost, return it to factory-new internal state, and ship it back programmed to your original VIN so it drops in and functions exactly as the day it left the factory. Karmanauto has been resetting Toyota airbag modules since 2006 — and the technician behind this service has been performing crash data resets since 1999, with over 25 years of hands-on experience on every Toyota Denso SRS module from the 1995 first-generation OBD-II Camry through the 2026 current-model-year Camry, Corolla, RAV4, Tacoma, Tundra, Highlander, 4Runner, Sienna, Sequoia, Land Cruiser, Supra, Prius, C-HR, bZ4X, GR86, GR Corolla, Crown, and every Toyota in between. This service covers every Toyota model, every model year from 1995 to 2026, every body style, every trim level, every transmission, every domestic and Japanese market variant, and every Toyota SRS module regardless of whether the airbags deployed, whether one airbag deployed, whether pretensioners fired, or whether the impact simply tripped the crash sensor without any visible deployment.

Seatbelt locked or stuck? Read this before you ship.
If your Toyota seatbelt is locked, stuck, or will not retract after a crash, the pyrotechnic pretensioner inside the belt has fired. A fired pretensioner is a physical, one-time deployment — same as an airbag. Resetting the module alone will NOT unlock the belt.
To clear the SRS light you must do both:
- Reset the module (this service) — clears the crash record and the pretensioner-fired flag from the EEPROM.
- Replace the seatbelt or deployed airbags (new or used) and the SRS light will clear.
Critical — Airbag Light On With NO Trouble Codes = Crash Data Locked
If your Toyota’s SRS warning light is on but Techstream, OBD-II, or any generic scan tool shows zero stored DTCs in the airbag system — the module almost certainly contains a hard-coded crash lockout. This is the single most misdiagnosed SRS symptom on Toyota, Lexus, and Scion vehicles.
Here is why this happens. When the Denso Center Airbag Sensor Assembly detects an impact above its internal crash threshold, it writes a hard crash flag directly to EEPROM and sets the internal lockout byte. Techstream only reports active DTCs from the live fault table — it does not read the EEPROM crash flag and it does not read the lockout byte. The result: the scanner reports “DTC Check Mode: Normal” or “No DTCs Present,” and the technician closes the case — but the module’s own firmware sees the lockout byte is set and refuses to extinguish the SRS warning lamp. The light stays on forever, no matter how many times you cycle the key or clear codes, because there are no codes to clear. The code has already been consumed into permanent storage.
Correct diagnostic order — always:
- Scan for DTCs first. Connect Techstream or a capable bidirectional scanner. Read codes from the SRS / Airbag system specifically — not just the engine.
- If codes ARE present, address the underlying cause first: squib open/short, sensor fault, wiring issue, failed pretensioner. Fix the physical problem. The code has to be repairable before any reset will hold.
- If NO codes are present but the SRS light is still on, the module has a stored crash flag in EEPROM that only a bench reset can clear. This is the most common finding on Toyotas after any impact — even a low-speed parking lot bump, a hard curb strike, a panic-braking event that tripped the front impact sensor, or a fender bender where no airbag deployed.
Do NOT replace clocksprings, impact sensors, seat buckles, occupant detection sensors, or SRS wiring harnesses before this check. Nine times out of ten, “airbag light on with no codes” is a locked module — not a bad component. Shops regularly spend $400 to $900 on replacement parts chasing this symptom before they realize the module itself is the problem. Bench-reset the module first. If the light clears on reinstall, the module was locked. If the light comes back with new active DTCs after the reset, now you have a real component fault to chase — but you have eliminated the #1 cause.
Why Karmanauto — Verifiable Expertise You Can Check Before You Ship Your Module
Most airbag reset services are anonymous drop-box operations with no public face, no technical content, and no way to verify the people handling your module know what they are doing. Karmanauto is different, and every claim on this page can be verified independently. 25+ years of hands-on crash reset experience. The lead technician at Karmanauto has been performing Toyota SRS module crash resets since 1999 — more than 25 years of continuous work on this exact system, across every generation of Toyota SRS architecture from first-generation flash-code Denso systems through current-gen CAN-bus Center Airbag Sensor Assemblies with integrated occupant classification and high-voltage hybrid safety coordination on Prius, RAV4 Hybrid, Camry Hybrid, Highlander Hybrid, and bZ4X. Karmanauto operating since 1999, online since 2006. Over twenty-five consecutive years of automotive electronic module reset and repair, with the same depth of accumulated Toyota-specific knowledge. Domain registration, business filings, and customer review history are all publicly verifiable. Vehix411 YouTube channel — public technical guides since 2008. You can verify the expertise before you ship. The Vehix411 YouTube channel publishes Toyota SRS module reset guides, Denso ECU repair walkthroughs, crash data decode videos, seatbelt pretensioner explanations, and module removal tutorials — eighteen years of dated video evidence of hands-on work. Thousands of subscribers, hundreds of videos, real customer cars on the bench, real Techstream captures, real before-and-after reset demonstrations. If you want to see the work before you pay for it, watch the channel. Training other shops since 2010 — hundreds of certified technicians nationwide. Karmanauto operates the Airbag Module Repair & Reset School, a professional training program teaching automotive repair shops, collision centers, and independent technicians how to perform Toyota, Lexus, Scion, Honda, and Acura SRS crash resets correctly and safely. Since 2010 — sixteen years — we have trained hundreds of shops across the United States in the exact procedures, tooling, and EEPROM-level techniques used every day in our own facility. You can verify this directly by visiting the Karmanauto Airbag Module Repair & Reset School page — it is live, public, and has been continuously available on our site. If your local body shop or electronics specialist is performing Toyota airbag resets, there is a meaningful chance they learned from our program. What this means for your module. When you ship a Toyota SRS module to Karmanauto, it is not being handled by a drop-box technician learning on your part. It is being reset by the people who teach other shops how to do this work — someone who has processed this exact generation of Toyota Denso SRS architecture tens of thousands of times, published public technical content about it, trained hundreds of competitors in the same procedures, and stands behind a public identity with a public YouTube channel and a twenty-year business record. If anything goes wrong with your reset, we are findable, contactable, and accountable — not an anonymous PO box.
When You Need a Toyota SRS Airbag Module Reset
Toyota SRS light stays on and won’t turn off
The most common reason a Toyota SRS light refuses to turn off is a stored crash code in the Center Airbag Sensor Assembly. This code is written permanently to EEPROM memory on impact and cannot be erased with Techstream, OBD-II, or any generic scan tool. The code stays forever until the module is either physically replaced or reset through direct EEPROM access at the chip level. If your Toyota SRS light has been on since an accident, since a front-end collision, since a parking lot bump, since a fender bender, or since any event where the car felt a sudden deceleration, your module has a stored crash code — and often with no accompanying DTCs visible on the scanner.
Toyota seatbelt is locked and won’t retract after an impact
This is one of the most misunderstood signals in the entire Toyota SRS system. A locked seatbelt combined with an illuminated SRS light almost always means a crash code has been stored, even if no airbag deployed. Toyota’s SRS system uses pyrotechnic seatbelt pretensioners that fire during sub-deployment impacts — the seatbelt retracts with force and then mechanically locks, and the pretensioner circuit reports “fired” to the Center Airbag Sensor Assembly. Once the module sees a fired pretensioner, it writes a permanent crash event record. No airbag deployment is required for this to happen. Customers often bring us Toyotas after minor impacts — a low-speed rear-end collision, a curb strike, a hard braking event that tripped the sensor, a parking lot fender bender — where the airbags did not deploy but the seatbelts locked and the SRS light came on. The module still has to be reset. The crash code is still stored. The seatbelt pretensioners still need to be replaced or refurbished. Once the module is reset and the pretensioner circuit resistance is back within spec, the SRS light clears, the module returns to factory state, and the car is ready for a new pretensioner install. If your Toyota seatbelt is stuck in the locked retracted position and the SRS light is on, you have a crash code. The module needs to be reset. This is true even if you did not crash — any event that fired the pretensioner circuit will cause this condition.
Toyota SRS light on after airbag replacement
After an airbag deployment, many shops replace the physical airbag and spiral cable but fail to reset the Center Airbag Sensor Assembly. The module still has the crash event in memory. The SRS light will not go out. This is the exact condition our service addresses.
Toyota SRS light blinking or flashing codes
On 1995–2000 Toyota models, the SRS module displays diagnostic trouble codes through the SRS warning lamp by flashing a pattern when the Tc terminal of the DLC1 or DLC3 diagnostic connector is grounded. If your SRS light is blinking a repeating pattern of flashes, the module is reporting a fault that needs diagnosis and often reset. We decode the flash pattern from your description and reset the stored code.
Dealer quoted a new airbag computer replacement
If a Toyota dealer has told you the Center Airbag Sensor Assembly must be replaced and quoted you $800–$1,400 plus labor and Techstream programming, a reset almost always solves the problem for a fraction of that cost. Replacement is only required if the module has physical circuit damage (extremely rare except in severe fires or flood). Stored crash data is not damage — it is simply a memory bit that needs to be reset.
Toyota airbag part-number coverage:
If your Toyota SRS control module starts with 89170 (format 89170-XXXXX), it is supported. The 89170 prefix covers every Toyota, Lexus, and Scion model from 1995 through 2026 — Denso units, every trim, every region. If the suffix on your module is not explicitly listed below, ship it anyway — we reset it.
Toyota 89170 Airbag Module Part Number Family Explained
Every Toyota SRS control module — formally called the “Center Airbag Sensor Assembly” in Toyota’s own service documentation — uses the 89170-XXXXX part number family. This is Toyota’s corporate part number prefix for the SRS ECU, applied company-wide across the Toyota, Lexus, and Scion brands. The suffix is typically five digits or a mix of digits and letters identifying model, body code, and production revision. Regardless of model, regardless of year, regardless of which Denso plant manufactured the module, if the part number on the module’s label begins with 89170, we reset and repair it. Examples of real Toyota 89170-prefix part numbers we have reset, organized by model family:

Toyota SRS Diagnostic Trouble Code Reference
This is the most complete Toyota SRS DTC reference you will find. We have pulled, decoded, and reset every code in this list. After a crash reset, every one of these codes clears — and the internal EEPROM crash flag that causes “light on with no codes” is erased at the same time.
Flash codes (1995–2000 pre-OBD-II)
Pre-OBD-II Toyota SRS diagnostics are read by jumping the Tc terminal of the DLC1 or DLC3 diagnostic connector to ground, then counting the flashes of the SRS warning lamp. Pattern: long flash (tens) + short flashes (ones).
- Flash 11: Short to ground — driver squib circuit
- Flash 12: Short to battery — driver squib circuit
- Flash 13: Open — driver squib circuit
- Flash 14: Short between driver squib wires
- Flash 15: Short to ground — passenger squib circuit
- Flash 16: Short to battery — passenger squib circuit
- Flash 17: Open — passenger squib circuit
- Flash 18: Short between passenger squib wires
- Flash 31: Center airbag sensor assembly internal fault
- Flash 43: Front impact sensor fault
- Flash 53: Side impact sensor fault (LH)
- Flash 63: Side impact sensor fault (RH)
- Flash B: Constant ON with no flash = permanent crash event recorded, module internally locked
If the SRS lamp is on solid with no flashing pattern after Tc is grounded, the module is reporting a permanent crash lockout. No flash means no active DTC — only the internal crash flag.
B-codes (2001+ OBD-II era — squib and deployment circuits)
Toyota adopted standard OBD-II Body codes for SRS diagnostics starting approximately 2001, depending on model. The complete Toyota B-code set we reset:
- B0100 / B0101 / B0102 / B0103 / B0104: Driver frontal airbag squib — open, short to ground, short to battery, low / high resistance
- B0105 / B0106 / B0107 / B0108 / B0109: Passenger frontal airbag squib — open, short, low / high resistance
- B0110 / B0111 / B0112 / B0113 / B0114: Driver side (thorax) airbag squib
- B0115 / B0116 / B0117 / B0118 / B0119: Passenger side (thorax) airbag squib
- B0120 / B0121 / B0122 / B0123 / B0124: Driver side curtain airbag squib
- B0125 / B0126 / B0127 / B0128 / B0129: Passenger side curtain airbag squib
- B0130 / B0131 / B0132 / B0133 / B0134: Driver knee airbag squib (where equipped)
- B0135 / B0136 / B0137 / B0138 / B0139: Passenger knee airbag squib (where equipped)
- B0140 / B0141: Driver far-side / center airbag (newer Camry, bZ4X)
- B1100 / B1101 / B1102: Driver seatbelt pretensioner — open, short, fired / deployment recorded
- B1110 / B1111 / B1112: Passenger seatbelt pretensioner — open, short, fired / deployment recorded
- B1125 / B1126: Rear LH / RH seatbelt pretensioner (where equipped)
- B1130: Active headrest squib (select models)
- B1155 / B1156: Occupant classification system calibration / weight sensor fault
- B1170 / B1171: Occupant detection module internal fault
- B1180: Seat position sensor fault
B1610–B1650 (Denso module internal faults)
Toyota-specific B1610-series codes record internal faults of the Center Airbag Sensor Assembly itself — power supply, internal memory, safing sensor, and crash-record integrity.
- B1610: Center airbag sensor assembly malfunction — internal
- B1611: Center airbag sensor assembly — configuration memory fault
- B1620: Center airbag sensor assembly — safing sensor internal fault
- B1630: Internal battery backup capacitor voltage fault
- B1650: SRS power supply voltage out of range / crash lockout active
- B1651: SRS power supply — low voltage
- B1652: SRS power supply — high voltage
If your Toyota module shows B1650 with an otherwise clean scan, the module is 100% storing crash data and is internally locked. Our reset clears every B1610-series code at the EEPROM level.
What our reset clears: We clear all crash-data codes. Some internal codes cannot be cleared — if it is a hardware issue with the module, no reset will clear it; if it is a software issue, it will clear.
B1800–B1825 (Impact sensor codes)
Toyota B1800-series codes log faults at the front, side, and rear satellite impact sensors that feed the Center Airbag Sensor Assembly.
- B1800 / B1801 / B1802: Front impact sensor (LH) — internal / circuit / signal
- B1803 / B1804 / B1805: Front impact sensor (RH) — internal / circuit / signal
- B1810 / B1811 / B1812: Side impact sensor (LH B-pillar) — internal / circuit / signal
- B1813 / B1814 / B1815: Side impact sensor (RH B-pillar) — internal / circuit / signal
- B1820 / B1821 / B1822: Rear impact sensor — internal / circuit / signal
- B1823 / B1824 / B1825: Floor / tunnel impact sensor
U-codes (network communication)
- U0073: Control module communication bus A — off
- U0100: Lost communication with ECM / PCM
- U0101: Lost communication with TCM
- U0121: Lost communication with ABS / VSC control module
- U0122: Lost communication with vehicle dynamics (VSC / stability)
- U0126: Lost communication with steering angle sensor
- U0151: Lost communication with restraint control module (SRS)
- U0155: Lost communication with instrument cluster / meter control
- U0293: Lost communication with hybrid vehicle control (Prius, RAV4 Hybrid)
- U0401: Invalid data received from ECM
- U0415: Invalid data received from ABS / VSC
- U1000 / U1001: CAN-bus initialisation fault / master node lost
Toyota crash / event memory (internal EEPROM records)
Toyota’s Denso Center Airbag Sensor Assembly writes crash events to internal EEPROM memory when a deployment or sub-deployment impact is detected. These records cause the permanent SRS light lockout even when no DTC is visible on Techstream. They are Denso-specific internal event bits — historical records that must be reset at the EEPROM level.
Every event record we clear — full list:
- Front impact event recorded — driver accelerometer threshold exceeded
- Front impact event recorded — passenger accelerometer threshold exceeded
- Front impact event recorded — floor / tunnel accelerometer threshold exceeded
- Side impact event recorded — LH B-pillar satellite sensor
- Side impact event recorded — RH B-pillar satellite sensor
- Side impact event recorded — driver door pressure-tube sensor (where equipped)
- Side impact event recorded — passenger door pressure-tube sensor
- Rear impact event recorded — rear satellite sensor threshold
- Rollover event recorded — roll-rate sensor threshold exceeded (4Runner, Land Cruiser, Sequoia)
- Pretensioner fire event recorded — driver seatbelt
- Pretensioner fire event recorded — passenger seatbelt
- Pretensioner fire event recorded — rear seatbelt (equipped models)
- Driver frontal airbag stage-1 deployment recorded
- Driver frontal airbag stage-2 deployment recorded (dual-stage inflator)
- Passenger frontal airbag stage-1 deployment recorded
- Passenger frontal airbag stage-2 deployment recorded
- Driver side (thorax) airbag deployment recorded
- Passenger side (thorax) airbag deployment recorded
- Driver side curtain airbag deployment recorded
- Passenger side curtain airbag deployment recorded
- Driver knee airbag deployment recorded (equipped models)
- Passenger knee airbag deployment recorded (equipped models)
- Front-center far-side airbag deployment recorded (2022+ Camry, bZ4X)
- Multi-event crash sequence recorded (two or more impacts)
- Sub-deployment threshold event recorded (impact below deployment threshold)
- Soft-crash event recorded (low-speed impact, pretensioner only)
- Rear-end impact no-deploy event
- Sensor validation mismatch event
- Crash power-down abort recorded
- Backup capacitor energised / crash power circuit activated
- Deployment command issued but not confirmed (latched fault)
- Module locked flag set — permanent one-time-use lockout active
Note: Toyota’s Techstream typically cannot see these internal EEPROM records. It only reads the live DTC table. This is why Toyota modules commonly present as “SRS light on with no codes” — the DTC table is clean, but the EEPROM crash flag is set. Our reset clears every stored event in this list regardless of DTC visibility.
A stored internal crash event is why your Toyota SRS light stays on after a minor fender bender where nothing deployed. Scan tools cannot clear these. Our reset clears every code in this list plus the EEPROM event records.
What the reset actually clears
Our reset clears the crash-related data stored in the Center Airbag Sensor Assembly after a collision: the permanent crash record, deployment commands, pretensioner fire records, multi-event sequences, and the internal EEPROM lockout flag. The module comes back to a non-deployed state so it stops triggering the airbag warning light from the crash event itself.
Our reset does not repair active fault codes caused by physical problems in the vehicle — for example a bad connector, broken wire, shorted spiral cable, failed pretensioner, unplugged sensor, or open-circuit squib. Those codes return on the scan tool the moment power is restored because the underlying fault is still present. If a B, U, or impact-sensor trouble code is caused by a real wiring or component issue, it has to be physically repaired in the vehicle.
Toyota SRS Module by Model
Toyota Camry SRS airbag module reset (1995–2026)
Toyota mounts the Camry’s Center Airbag Sensor Assembly on the transmission tunnel beneath the center-console tray across every generation from the 1997 XV20 through the current XV70. The earlier XV10 (1995–1996) uses a different layout with the ECU seated under the driver’s seat. Part number series 89170-06XXX, 89170-33XXX, 89170-AAXXX cover all Camry generations. The Camry Hybrid (2007+) and Camry Solara coupe (2002–2008) share the module architecture with standard Camry. We reset crash codes, clear stored deployment events, repair seatbelt pretensioner circuit faults, and return the module programmed to your original VIN. Same-day turnaround on Camry modules.
Toyota Corolla SRS airbag module reset (1995–2026)
On the Corolla, the airbag ECU sits inside the center-console cavity from the E120 generation (2003–2008) onward. E110 (1998–2002) and earlier Corollas follow the same internal placement. Part numbers 89170-02XXX (2003–2014), 89170-12XXX (2014–2019), 89170-1AXXX (2020–2026 E210 chassis). Covers Corolla Sedan, Corolla Hatchback, Corolla Cross, GR Corolla, and Corolla Hybrid.

On the RAV4, the SRS computer is bolted to the chassis floor beneath the center-console stack from the XA30 (2006–2012) onward. XA10 (1996–2000) and XA20 (2001–2005) use the same mounting zone. Part numbers 89170-42XXX (2006–2018), 89170-0RXXX (2019–2026 XA50 chassis). The RAV4 Hybrid and RAV4 Prime Plug-in Hybrid use the same SRS architecture with an additional high-voltage battery cutoff input that coordinates with the hybrid vehicle control module during a crash. We reset crash codes, clear pretensioner fire events, and handle the occupant classification calibration that RAV4 modules require after front passenger seat events.
Toyota Tacoma SRS airbag module reset (1995–2026)
The Tacoma’s airbag sensor assembly is fastened below the center-console bracket on both the 2nd generation (2005–2015 AN10) and 3rd generation (2016–2023 AN20). 1st generation Tacomas (1995–2004) share the same placement. Part numbers 89170-04XXX across all generations. Current 4th generation Tacoma (2024+ N400) uses updated 89170-04 series with CAN-FD communication. Tacoma TRD Off-Road, TRD Pro, and TRD Sport all use the same module family within each generation.
Toyota Tundra SRS airbag module reset (2000–2026)
Tundra SRS modules are housed below the center-console compartment on the XK50 (2007–2021) and XK70 (2022–2026) platforms. The earlier XK30/XK40 (2000–2006) trucks are built the same way. Part number prefix 89170-0CXXX across all generations. Tundra 1794 Edition, Limited, Platinum, SR5, and TRD Pro all use the same module family. The 2022+ Tundra iForce Max Hybrid uses the same SRS with additional HV battery crash cutoff coordination.
Toyota Highlander SRS airbag module reset (2001–2026)
Highlander airbag ECUs live under the center console, anchored to the floor pan across XU40 (2008–2013), XU50 (2014–2019), and XU70 (2020–2026). The earlier XU20 (2001–2007) uses the same internal bay. Part numbers 89170-0EXXX and 89170-48XXX. Highlander Hybrid (all generations) uses the same SRS architecture with hybrid system integration.
Toyota 4Runner SRS airbag module reset (1996–2026)
The 4Runner’s Center Airbag Sensor Assembly is installed beneath the center-console trim on both N210 (2003–2009) and N280 (2010–2024). N180 units (1996–2002) are wired into the same zone. Part number prefix 89170-35XXX. The 2025+ N300 Generation 6 4Runner uses updated 89170 series with rollover sensor integration for the optional off-road TRD Pro package.
Toyota Sienna SRS airbag module reset (1998–2026)
Sienna SRS modules sit on the chassis floor beneath the center-console cover on both XL30 (2011–2020) and XL40 (2021–2026). XL10 (1998–2003) and XL20 (2004–2010) vans use the same mounting. Part number prefix 89170-08XXX. Sienna sliding-door side curtain coverage, 3-row seatbelt pretensioners, and occupant classification on 2nd and 3rd row all handled correctly in the reset. The 2021+ XL40 Sienna is hybrid-only and coordinates with the HV battery system.
Toyota Prius SRS airbag module reset (2001–2026)
The Prius airbag ECU tucks below the center-console trim from the XW20 (2004–2009) onward. The first-generation XW10 (2001–2003) is the sole exception — its module lives behind the driver-side kick panel. Part number prefix 89170-47XXX across Prius, Prius Prime, Prius C, and Prius V. The Prius hybrid system places additional safety requirements on the SRS module — high-voltage battery disconnect coordination during a crash event — which our reset preserves intact.

SRS safety notes for all removals
Always disconnect the negative battery terminal and wait a minimum of 3 minutes before touching any SRS wiring. Toyota SRS modules contain a backup capacitor that retains enough charge to fire airbags for up to 3 minutes after battery disconnect. Do not use electrical test equipment on deployment circuits. Do not apply 12V to any SRS circuit under any circumstance. Store removed modules in their original ESD-protective bag or wrap in anti-static material for shipping. On hybrid and EV Toyotas (Prius, RAV4 Hybrid, Camry Hybrid, Highlander Hybrid, Sienna 2021+, bZ4X, Mirai) also perform the Toyota HV-service-plug removal procedure per the model-specific service manual before touching any orange-cable circuit.
The Karmanauto Toyota SRS Reset Process
When your Toyota SRS module arrives at our facility, here is exactly what happens.
- Intake and inspection. Your module is logged into our tracking system with your customer ID. Part number, VIN, and shipping date are recorded. The module is visually inspected for water damage, burn marks, connector pin damage, and physical cracks.
- Bench power-up. The module is connected to our bench harness that simulates the Toyota vehicle environment. Power, ground, CAN-bus, and all squib circuits are simulated with dummy loads at the correct Denso-specified resistance values.
- Initial code read. We read every stored code — B-codes, U-codes, B1610-series internal codes, B1800-series impact-sensor codes, and internal EEPROM event memory. A pre-reset report is generated and attached to your file.
- EEPROM access. Our Denso-specific programmer connects to the module’s EEPROM chip via the correct access pin configuration. Every Toyota module generation uses a slightly different EEPROM access sequence — we have the tooling and know-how for all of them.
- Crash data erase. The specific EEPROM bytes that hold crash records, deployment flags, pretensioner fire events, multi-event crash sequences, and the internal lockout flag are rewritten to their factory-default pattern. This is the step that no Techstream scan tool can perform.
- VIN integrity check. Your original VIN and configuration bytes are preserved. The module comes back with your exact VIN, your exact factory options, your exact production-date configuration. It will not throw a “wrong VIN” code when installed back in your Toyota.
- Post-reset verification. The module is re-read after the erase. Every code from step 3 is confirmed cleared. A post-reset report is generated.
- Functional test. All squib circuits are tested at factory resistance specifications using our bench simulator. Communication with the simulated CAN-bus is verified. Sleep-mode current draw is measured. Wake-up timing is measured.
- Packaging and shipping. The module is placed in a new ESD-protective bag, cushion-wrapped, and shipped in a rigid box back to your address via the return method you selected.
Total turnaround: Same-day processing for modules arriving before 2pm local time. Standard shipping is FedEx Ground. Overnight options available.
Warranty, Turnaround, and Shipping
Our guarantee: Your module’s EEPROM is backed up on our servers before the reset and after the reset, filed under your order number. Reminder: the module reset alone will not clear the SRS light if a seatbelt pretensioner has fired — the fired belt must be replaced or rebuilt separately. See the seatbelt warning at the top of this page. The crash reset itself is guaranteed — if the module returns to your vehicle and does not clear the SRS light (assuming your installation is correct and your peripheral components are within spec), we recheck and re-reset it free. Every job is traceable by order number, before and after. This is a recheck guarantee, not a lifetime warranty — we do not claim anything we cannot honestly stand behind. Turnaround: Same-day reset processing for modules received by 2pm. Typical customer experience: ship Monday morning, arrives Tuesday, reset Tuesday, returns Wednesday or Thursday. Shipping: Ship your module to our facility using any trackable method. FedEx Ground is fastest for continental US. International customers: we service Toyota modules shipped from Canada, Mexico, UK, EU, Australia, and most other markets. Packaging: Wrap the module in anti-static bubble wrap or ESD bag, place in a rigid cardboard box with padding, include a slip of paper with your name, phone number, email, return address, and vehicle VIN. Questions about your specific part number, module location, or whether your situation is covered? Contact us before you ship — we would rather answer a part number question up front than have your module sit on the bench waiting for info.

Frequently Asked Questions
Can a Toyota airbag module be reset after a crash?
Yes. Every Toyota Center Airbag Sensor Assembly with part number prefix 89170 can be reset after a crash. The crash record is stored in EEPROM memory and is cleared through direct EEPROM access. A dealer will tell you the module must be replaced — this is not true unless the module is physically damaged. Resetting is a simple data operation that restores the module to factory state.
My Toyota SRS light is on but Techstream shows no codes. Is the module still the problem?
Yes — this is the most common and most misdiagnosed Toyota SRS scenario. The Denso Center Airbag Sensor Assembly writes crash flags to internal EEPROM that Techstream cannot read. The module sees the lockout byte and keeps the SRS light on, even though the live DTC table is empty. A bench reset is the only fix. Do not replace clocksprings, sensors, or seat buckles before ruling out a stored EEPROM flag.
Is it legal to reset a Toyota airbag module after an accident?
Yes. Resetting your own vehicle’s airbag module after a crash is legal in every US state, every Canadian province, and most international jurisdictions. The module is your property. The data in it is your property.
How long does it take to reset my Toyota SRS airbag module?
Same-day processing for modules arriving at our facility before 2pm. Total turnaround from ship to return is typically 2–4 business days.
Will the airbag light come back on after you reset my Toyota module?
No — provided the original cause of the crash code has been addressed. If deployed airbags have been replaced, if deployed seatbelt pretensioners have been replaced, if damaged impact sensors have been replaced, and the module wiring harness is intact, the SRS light stays off permanently after reset.
My seatbelt is locked and the SRS light is on. Did the airbags deploy?
Not necessarily. Toyota seatbelt pretensioners can fire during sub-deployment impacts — the belt retracts, locks, and fires the pyrotechnic pretensioner without any airbag deploying. When the pretensioner fires, the module records a permanent crash event. The SRS light comes on and stays on. The seatbelt locks and will not retract. The module must be reset, and the fired seatbelt pretensioner must be replaced. The airbags in your Toyota are still functional — they simply did not deploy because the crash was below airbag threshold but above pretensioner threshold.
I had a minor fender bender and my SRS light is on. Do I need a reset?
Yes. Even minor low-speed impacts can trigger the crash sensor or fire a seatbelt pretensioner and store a permanent crash record. The module needs to be reset. Your airbags are likely still fully functional.
Can I drive my Toyota with the SRS light on?
Mechanically yes, but not safely. The SRS light being on means your airbag system is in fault state — airbags may not deploy in a subsequent crash. Most states will not pass safety inspection with the SRS light on.
Where is the airbag control module located in my Toyota?
Most 2005+ Toyotas have it under the center console on the transmission tunnel. Every Toyota SRS airbag control module we reset lives in the center console, regardless of model year or generation. That includes earlier Camry (XV10), Corolla (E110 and older), Tacoma 1st gen, RAV4 XA10/XA20, 4Runner N180, Tundra XK30/XK40, Highlander XU20, Sienna XL10/XL20, Yaris, Prius (XW10 and later), and Supra A90 — all center-console-mounted.
Do I need any programming or coding after the Toyota airbag module reset?
For most Toyota vehicles — no additional programming is needed. We preserve your original VIN and configuration bytes during the reset. Plug the module back in, reconnect the battery, the SRS light goes out, and you are finished. Exceptions: 2018+ Camry, Corolla, RAV4, and Highlander may need a brief Techstream-based occupant classification re-zero after reinstall (5–10 minutes with Techstream or a capable bidirectional OBD-II scan tool). Toyota hybrid and EV models (Prius, RAV4 Hybrid, Camry Hybrid, bZ4X, Mirai) plug back in without programming but follow model-specific HV-service procedures for safe reinstall.
How much does it cost to reset a Toyota airbag module?
Substantially less than dealer replacement. Dealer replacement runs $800–$1,400 plus labor and Techstream programming. See the price on this page for current reset service pricing.
Will Toyota dealers detect the reset?
No. After our reset the module returns to factory state. A dealer Techstream reads the module as having zero codes and zero history.
What if my Toyota has aftermarket airbags or seatbelts?
Aftermarket SRS components often have incorrect circuit resistance and will cause the module to throw codes on power-up. We recommend OEM Denso or OEM-equivalent SRS parts only.
What if my Toyota is a salvage title or rebuilt title?
We reset SRS modules on any Toyota regardless of title status — salvage, rebuilt, reconstructed, clean, all the same to us.
Do you service Toyota models sold outside the US?
Yes. Canadian, Mexican, European, UK, Australian, Middle Eastern, and JDM Toyotas all use the same 89170 part number family. Ship internationally; we service the module and return it.
My part number starts with 89170 but I do not see it in your list. Is it covered?
Yes. Our list of example part numbers is not exhaustive. Every 89170-prefix module is covered. Ship it to us; we reset it.
Do you service Lexus and Scion as well?
Yes. See our Lexus airbag module reset and Scion airbag module reset services. Lexus and Scion share the same Denso 89170 architecture as Toyota.
What about the seatbelt pretensioners — do you replace those?
We reset the module’s record of pretensioner firing, but we do not supply replacement pretensioners. Fired seatbelt pretensioners are mechanical parts that must be replaced with new OEM or OEM-equivalent pretensioners.
Do you work with body shops and collision repair facilities?
Yes. We service collision repair facilities across North America. Same-day turnaround, wholesale pricing available. We also train shops in airbag reset procedures via our Airbag Module Repair & Reset School.
Where can I verify your expertise before shipping my module?
Three independent places. Visit the Vehix411 YouTube channel — eighteen years of dated technical video guides on Toyota SRS module reset, Denso ECU repair, and automotive electronics, continuously published since 2008. Visit the Karmanauto Airbag Module Repair & Reset School — live on our site, hundreds of shops trained since 2010. And Karmanauto has been in business since 1999, with Karmanauto.com in continuous online operation since 2006. Ask your local body shop if they have trained with Karmanauto’s airbag reset school — many have.

Robert (verified owner) –
2002 Toyota Tacoma TRD: Service was quick and reliable. The first person I dealt with, Olga, was very responsive and explained how to use the service. I provided Karman with a history of the part and the problem when I sent it in. When it came back someone had written OK on the unit and there was no written explanation of testing results or what was done. If the part was operating perfectly when it was tested, I would have like to have known that based on the information provided. I am assuming it was fine. Unfortunately for me, the unit was installed, my master mechanic used a quality scanner, no DTC was detected, and I still have the red light. I called Karman, spoke to a tech, and he opined I may have the wrong part. I double checked and that is not the case, so my investigation continues. I dropped them one mark based on not being provided more information on the testing result of part I sent in. I believe the service they provide is valuable at a fair price.
