Chevrolet Airbag Module Reset — $75 flat
Chevrolet 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.
Chevrolet 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 Chevrolet
What we reset on a Chevrolet
GM SDMs latch a deployment record that permanently locks the module — the airbag light stays on and a scan tool reports the crash state no matter how many times you clear codes. We reset the SDM's EEPROM on the bench so the original, VIN-matched module goes straight back in.
Where it lives: under the center console or under a front seat, depending on model. Disconnect the battery, wait 10+ minutes, photograph the connectors, unbolt and ship just the module.

Chevrolet reset questions
How much does the dealer charge instead?
A new module is typically $350–$1,200 in parts depending on the Chevrolet model, plus installation and programming labor. Our bench reset of your original is a flat $75, with 24–48 hour bench turnaround.
Where is the SDM on my Chevrolet?
Typically under the center console or under a front seat, depending on model. Disconnect the battery and wait 10+ minutes before unplugging it, photograph the connectors, and ship just the module — see the packing instructions in your confirmation email.
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 Chevrolet 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.
