Mazda Airbag Module Crash Reset Repair Service

Mazda Airbag Module (SAS) Crash Reset & Repair Service — Mail-In, 24-Hour Turnaround

Mazda’s SAS (Sophisticated Airbag Sensor) module stores permanent crash codes and an internal lockout byte after any airbag deployment. Mazda IDS and M-MDS dealer tooling cannot clear them. A new SAS from the dealer runs $700-1,300 VIN-coded. Our bench service reads the EEPROM directly, wipes crash codes and the lockout, and ships the module back plug-and-play.

Models This Service Covers

Mazda 2, Mazda 3, Mazda 5, Mazda 6, CX-3, CX-30, CX-5, CX-50, CX-70, CX-7, CX-9, CX-90, MX-5 Miata (ND, NC, NB), MX-30, Tribute, B-Series, RX-8, Protege, Mazdaspeed 3, Mazdaspeed 6, CX-8, RX-7.

If your part number is not on this list, send a photo of the label on the airbag module and we will confirm within the hour — we process the entire Mazda airbag module family plus Continental, Bosch, Siemens VDO, TRW, and Denso variants.

How Our Crash Reset Works

1. You email us the label first. Snap a photo of the airbag module part number sticker and email it to us. We confirm your unit is supported and send the prepaid shipping label.
2. You remove the module from the car. The module is under the center console, bolted to the transmission tunnel, on every modern Mazda — accessed by removing the shifter surround and center console side trim. Disconnect the battery for at least 10 minutes first, then unbolt and unplug the module.
3. Mail it to us. Wrap in bubble wrap or anti-static foam, drop in a padded envelope or small box, and use the label we sent. Insurance is included. Most orders reach our bench in 1-2 business days.
4. We bench-read the EEPROM. We pull your module’s EEPROM directly on the bench — no soldering, no damage. We inspect for hard-coded deployment flags, blown squib resistors, and crash history counters.
5. We clear the crash data and lockout. We wipe every deployment flag, crash log entry, event data recorder, and the internal lock byte that prevents dealer tools from resetting the module. We write the EEPROM clean at the bit level so the codes never come back.
6. Bench verification. Before we ship it back, we bench-test the module with a simulator to confirm all deployment circuits read OPEN, the internal lockout is cleared, and the module communicates normally over CAN/K-Line.
7. We ship it back. 24-hour bench turnaround, same-day return shipping (USPS Priority or UPS 2-Day, tracked). Plug-and-play — bolt it back in, reconnect the battery, and the airbag light goes out on the first key-on. No dealer scan tool required.

Mail-In Instructions

Ship your airbag module to:
Karman Auto — Airbag Reset Service
(address provided on your receipt after payment — you cover shipping in, and return shipping is paid at checkout on our site)

Please include a note with your name, phone number, and order number inside the package. We do not need the airbag itself — only the SRS / SDM / ORC / RCM / ACSM electronic control module (the small metal or plastic box with a connector, usually 4 to 8 inches long). Do not ship any undeployed airbags, pyrotechnic parts, or seatbelt pretensioners — those are hazmat and cannot legally go through the mail. Just the control module.

Turnaround, Warranty, and Pricing

Flat-rate service, no hidden fees. 24-hour bench turnaround from the moment your module arrives at our shop. 12-month warranty backed by over 25 years of crash-reset experience. We save the before-and-after EEPROM files on every module in-house so we can always verify the reset if any question comes up later.

Questions about your specific part number, your car’s 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

How long does the Mazda airbag module reset take?
24 hours on the bench from the moment your Mazda module arrives at our shop. Most customers are back on the road within 3-5 business days end-to-end, including shipping both ways.

Will the airbag light stay off after you reset my Mazda module?
Yes. We wipe every crash flag, deployment counter, and internal lockout byte at the EEPROM level, then bench-verify the module before it ships. Plug it back in, reconnect the battery, and the airbag light goes out on the first key-on — no dealer scan tool required. Backed by our 12-month warranty and 25+ years of crash-reset experience.

Do I need to send the airbags too, or just the Mazda control module?
Just the control module — the small SRS / SDM / ORC / RCM / ACSM electronic box. Do not ship any undeployed airbags, pyrotechnic parts, or seatbelt pretensioners. Those are hazmat and cannot legally go through the mail.

How do I know if my Mazda part number is supported?
Email us a photo of the label on your Mazda airbag module before you ship. We confirm support and part coverage within the hour during business days. If we cannot reset your specific unit, you will not be charged.
