Mazda Airbag Module Reset — $75 flat
Mazda calls it the SAS Control Module (SAS unit). After a deployment it locks its crash data — the light stays on and no scan tool clears it. We reset your original module on the bench, 24–48 hours, plug-and-play on return.
Mazda dealer: new SAS unit typically $350–$1,200 + programming + the wait for the part
Auto Module Lab: $75 flat — your original module, already matched to your Mazda
What we reset on a Mazda
Mazda's SAS (Sophisticated Airbag Sensor) unit records the crash and locks. We clear it on the bench; your original returns plug-and-play with no dealer step.
Where it lives: under the center console area. Disconnect the battery, wait 10+ minutes, photograph the connectors, unbolt and ship just the module.

Mazda reset questions
Do you need my VIN?
It helps — add it at checkout and we verify the module matches your vehicle before the bench work. It's optional, but it catches mixed-up modules from body shops handling several cars.
Will clearing the crash data turn my Mazda airbag light off?
Yes — when the light is caused by stored crash data or hard faults in the SAS unit, clearing it removes the cause. You still need the rest of the system healthy: deployed airbags, blown seat-belt tensioners, or damaged impact sensors must be replaced or the light will return with live codes.
Is a reset safe? Will the airbags still work?
A reset returns the module to its pre-crash state — the same state it shipped in before the deployment. It does not alter the deployment logic. After reinstalling, the system self-tests on every key cycle exactly as designed. If we find internal damage that a reset can't make right, we tell you and refund instead of shipping back a module we wouldn't put in our own car.
Why not just buy a used SAS unit?
Used Mazda modules usually carry the donor car's coding — and on many platforms they're VIN-married, so the car rejects them or needs dealer programming. Your original module is already matched to your vehicle; clearing it keeps everything plug-and-play.
