Buick Airbag Module Reset — $75 flat
Buick calls it the Sensing & Diagnostic Module (SDM). 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.
Buick dealer: new SDM typically $350–$1,200 + programming + the wait for the part
Auto Module Lab: $75 flat — your original module, already matched to your Buick
What we reset on a Buick
Buick SDMs lock after a deployment like every GM module of the era. We clear the crash record and return your original module ready to bolt in — no dealer setup appointment.
Where it lives: under the center console area. Disconnect the battery, wait 10+ minutes, photograph the connectors, unbolt and ship just the module.

Buick 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 Buick airbag light off?
Yes — when the light is caused by stored crash data or hard faults in the SDM, 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 SDM?
Used Buick 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.
