What is a Pontiac Bonneville SE airbag control module?
The Pontiac Bonneville SE airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle, making it critical to your safety.
This system, also known as SRS SDM (Sensing Diagnostic Module), is responsible for detecting collisions and quickly deploying airbags and seatbelt pretensioners.
It also offers a comprehensive self-diagnosis function that detects malfunctions in the airbag system and displays them in the cockpit.
Why is the Pontiac Bonneville SE airbag control unit defective?
A Pontiac Bonneville SE airbag control module can fail because it permanently stores crash data after an accident, causing it to lock up, or due to internal malfunctions that can be caused by age, power surges, or moisture, requiring replacement or specialized repair.
After the airbags are deployed, the control unit stores accident data and usually needs to be reset to function again.
Failure can also be caused by internal electronic problems or age-related material fatigue, which impairs system diagnostics.
Such defects often result in the airbag warning light remaining permanently lit and the system no longer fulfilling its protective function.
Common error codes for Pontiac Bonneville SE airbag control unit repair
During Pontiac Bonneville SE airbag control unit repair, specific error codes typically occur that indicate a problem directly in the module or its communication, such as B1000 for communication errors or B0091 for internal control unit problems.
- B1000 → Control unit communication error → Signal disturbance between airbag control unit and vehicle systems.
- B0091 → Control Module Issues → Internal malfunction or damage to the airbag control unit itself.
These diagnostic codes are crucial to identifying the exact problem and initiating the necessary Pontiac Bonneville SE airbag control unit repair.
What part numbers are available for the Pontiac Bonneville SE airbag control unit repair?
For the Pontiac Bonneville SE airbag control unit repair, two original OEM part numbers from General Motors are primarily relevant: 25725745 and the alternative 12204250, both of which have been validated for the 2001-2003 model years of the Pontiac Bonneville SE.
- 25725745 → GM (General Motors) → Original airbag control unit (SRS SDM) for Pontiac Bonneville SE (2001-2003).
- 12204250 → GM (General Motors) → Alternative OEM part number for the same airbag control unit, replaces and fully compatible.
These precise part numbers ensure that your Pontiac Bonneville SE airbag control unit repair uses the correct replacement part or resets the existing module accordingly.
Compatibility is crucial because the airbag control unit must be VIN-specifically programmed to function properly.
