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.

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.

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 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.

Toyota SRS Module Removal by Chassis Family

Toyota center-console SRS module removal (Camry 1997+, Corolla 2003+, RAV4 2006+, Highlander all, 4Runner 2003+, Sienna 2011+, Tundra 2007+, Sequoia all, Land Cruiser, Avalon 2005+, most Prius, most C-HR, bZ4X)

1. Disconnect the negative battery terminal. Wait 3 minutes for SRS backup capacitor discharge.
2. Remove the front floor center console trim. On most Toyotas this is 2–4 Phillips or 10mm screws under the shift boot or console lid, plus plastic clip fasteners along the sides.
3. Remove the center console armrest assembly. Disconnect any USB, 12V, HDMI, or seat-heater harnesses.
4. Lift the carpet to expose the SRS module mounting bracket on the transmission tunnel.
5. The Center Airbag Sensor Assembly is a yellow or black rectangular Denso unit with a single multi-pin harness connector. Release the connector’s sliding lock first, then lift the lever to disconnect.
6. Remove the three or four 10mm or 12mm bolts holding the module to the tunnel bracket and lift it out.

1. Disconnect negative battery, wait 3 minutes.
2. Remove the center console trim. Most Toyota consoles use four 10mm bolts plus clipped side panels.
3. Lift out the console tray/liner, disconnect the harness connectors that run through the console, and set the console parts aside on a clean blanket.
4. The Center Airbag Sensor Assembly is mounted to the floor pan directly below or slightly forward of the seat. Release connector lock, disconnect, remove mounting bolts (typically 10mm), lift out.

Toyota Prius kick-panel SRS module removal (XW10 2001–2003 only)

1. Disconnect negative battery, wait 3 minutes. Power down the HV system per Prius procedure.
2. Remove the driver’s-side lower dash trim and kick panel.
3. The SRS module is mounted to the firewall behind the kick panel. Release connector lock, disconnect, remove mounting bolts, lift out.

Toyota Supra A90 console SRS module removal (2020+)

1. Disconnect negative battery, wait 3 minutes.
2. Remove the center console side trim panels (BMW-style clip fasteners).
3. Remove the center armrest, shifter surround, and center stack lower trim.
4. The 89170-WAA Center Airbag Sensor Assembly is mounted to the tunnel behind the shifter. Release connector, remove mounting bolts, lift out. Handle gently — the A90 module uses a hybrid Denso/Bosch internal architecture.

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.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.

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.
