GM Airbag Reset Questions: B0051, B0101, SDM Codes & Part Numbers
Quick Answer: If your GM airbag light stays on after an accident and codes like B0051, B0053, B0101, or B1000 will not clear, the SDM airbag module may still contain stored crash data. These crash-related codes are usually not removable with a normal scan tool because the event data is stored inside the module memory.
This page answers common GM airbag reset questions for Chevrolet, GMC, Cadillac, Buick, Hummer, Pontiac, Saturn, and Oldsmobile vehicles. It covers SDM crash codes, part-number families, scan-tool limitations, reset vs replacement, and what to check before ordering service.

GM Airbag Reset Questions and Answers
Q: Why will my GM airbag codes not clear after an accident?
After a collision, the GM SDM can store crash-event data that returns even after a scanner attempts to erase the code. If airbags, pretensioners, or impact events were recorded, the module may need a memory-level reset before the airbag light can stay off.
Q: What is a GM SDM?
SDM stands for Sensing and Diagnostic Module. It is GM’s airbag control module responsible for monitoring crash sensors, airbags, and deployment events.
Q: Can a scan tool clear GM airbag crash data?
No. Scan tools can clear temporary SRS faults, but crash-event data stored after deployment is typically locked and will return until the module memory is corrected.
Q: Why does my Chevy say “Service Air Bag” after a crash?
This message appears when the SDM stores crash data or detects a system fault that will not clear. If it returns after repairs, the module may still be locked.
Q: What is GM code B0051?
B0051 is one of the most common GM crash-related codes and indicates a recorded deployment event. If it will not clear, the SDM usually still contains crash data.
Q: What is GM code B0053?
B0053 is another deployment-related code. If it returns after clearing, the module may still contain stored crash history.
Q: What is GM code B0101?
B0101 may indicate an internal SDM fault or crash-related condition depending on the vehicle. After an accident, it often points to stored module data that must be corrected.
Q: What is GM code B1000?
B1000 is an internal module fault code. After a crash, it may be related to locked crash data or memory issues inside the SDM.
Q: What GM airbag codes usually require reset?
Common post-crash codes include B0051, B0053, B0101, B1000, B0020, B0022, B0024, B0026, B0028, B0071, and B0081 when they are tied to deployment events.
GM SDM Part Number Questions
Q: Can a GM airbag module be identified by part number?
Yes. GM SDM modules use 10-digit part numbers printed on the label. These numbers help identify the module family.
Q: What GM part numbers are commonly reset?
Common GM SDM part numbers start with 13xxxxxxx, 15xxxxxxx, 20xxxxxxx, 22xxxxxxx, and 25xxxxxxx across many GM vehicles.
Q: My part number starts with 15. Is it resettable?
Many 15xxxxxxx SDM modules are used on GM trucks and SUVs and can be reset if the module is readable and not damaged.
Q: What if I only have the part number?
A clear photo of the module label is usually enough to identify the SDM type and confirm if it can be reset.
Reset vs Replacement Questions
Q: Do I need to replace my GM airbag module?
Not always. If the module is readable and not physically damaged, it may be reused after the crash data is cleared.
Q: Will resetting keep VIN and configuration?
Yes. The original data remains stored in the module when properly reset.
Q: Will this fix the airbag light?
If the only issue is stored crash data, yes. If the light stays on, there may still be a wiring, sensor, or deployed component issue.
Q: Does reset fix deployed airbags or seatbelts?
No. Physical components must still be replaced or repaired.
Q: Can disconnecting the battery reset crash data?
No. Crash data remains stored even without power.
DIY and System Questions
Q: Can I reset the module myself?
Only with proper EEPROM tools and experience. Incorrect changes can cause communication failure or module damage.
Q: Why does crash data stay stored?
The SDM records crash events in protected memory so they cannot be erased with normal scan tools.
Q: What happens if crash data is not cleared?
The airbag system may remain disabled and the warning light will stay on.
Location Questions
Q: Where is the GM airbag module located?
Usually under the driver seat, passenger seat, or center console depending on the model.
Q: What should I send for service?
Send only the SDM airbag module. Do not ship airbags or seatbelt components.
Need GM Airbag Module Reset?
If your GM vehicle has an airbag light after an accident, a “Service Air Bag” message, or codes like B0051 or B0101 that will not clear, your module may need reset.
