What is a Pontiac Grand Am 1999-2005 airbag control module?
The Pontiac Grand Am 1999-2005 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It continuously monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules and seatbelt pretensioners in the vehicle to provide maximum safety.
This electronic control unit, also known as the SRS Control Module, is essential for the Supplemental Restraint System (SRS). It processes signals from various sensors to react precisely in the event of a collision.
The module also continuously diagnoses the condition of the entire airbag system. If a malfunction is detected, a warning light is activated in the dashboard, indicating that a check is necessary.
Why is the Pontiac Grand Am 1999-2005 airbag control module defective?
The Pontiac Grand Am 1999-2005 airbag control unit often fails due to internal component failure, crash data stored after an accident, or electrical malfunctions. The system may then no longer deploy the airbags correctly, significantly compromising vehicle safety and requiring professional repair.
Common causes of failure include internal errors in the module itself, which can develop over time. Water damage or power surges are also possible triggers for failure.
After an accident, the control unit stores so-called crash data, which renders it unusable for subsequent operation. Simply clearing the error is not sufficient in this case, as a specialized hardcode reset is required.
Early diagnosis of airbag warning lights is critical to ensuring the safety of your Pontiac Grand Am and preventing more costly subsequent damage.
Common error codes for Pontiac Grand Am 1999-2005 airbag control unit repair
When repairing the Pontiac Grand Am 1999-2005 airbag control module, error codes like B1000, B0010, or B0091 often indicate direct problems with the module. These B-codes signal communication errors, ignition circuit problems, or internal module defects that require specific diagnosis and repair.
- B1000 → Control unit communication error → Airbag ECU
- B0010 → Driver airbag ignition circuit short circuit to ground → Airbag control unit
- B0011 → Driver airbag ignition circuit short circuit battery → Airbag control unit
- B0012 → Driver airbag ignition circuit error → Airbag control unit
- B0013 → Driver airbag deployment circuit malfunction → Airbag control unit
- B0014 → Driver airbag terminal 1 interruption → Airbag control unit
- B0015 → Driver airbag terminal 2 interruption → Airbag control unit
- B0016 → Passenger airbag ignition circuit resistance high → Airbag control unit
- B0017 → Passenger airbag firing circuit resistance low → Airbag control unit
- B0018 → Passenger airbag ignition circuit short circuit battery → Airbag control unit
- B0020 → Passenger airbag ignition circuit short circuit to ground → Airbag control unit
- B0021 → Passenger airbag trigger circuit open → Airbag control unit
- B0022 → Passenger airbag activation circuit malfunction → Airbag control unit
- B0091 → Control unit (Airbag Control Module) internal error → Airbag control unit
These specific trouble codes relate directly to the SRS control module, not to sensors or seatbelt pretensioners. They are crucial for an accurate diagnosis when the airbag warning light illuminates in the Pontiac Grand Am.
A professional reset is essential, especially if crash data is stored, as simply erasing the error codes isn't enough. Our workshop offers comprehensive repair assistance.
What part numbers are available for the Pontiac Grand Am 1999-2005 airbag control unit repair?
For the Pontiac Grand Am 1999-2005 airbag control unit repair, two verified OEM part numbers from General Motors are relevant: 16238589 and the alternative 09369720. These ensure compatibility and correct function in the vehicle, as they have been directly validated for this model.
Part number 16238589 is the primary original OEM part number for the airbag control module in the 1999-2005 Pontiac Grand Am. It is manufactured by General Motors and is confirmed by various trusted sources.
Another alternative OEM part number, 09369720, is also validated and suitable for the same application. Both numbers are specific to the SRS Control Module and not to any other sensors or components.
When replacing the defective module, it is crucial to use one of these verified OEM numbers. After installation, the control unit usually needs to be re-adapted or reprogrammed to the vehicle's vehicle identification number (VIN).
This ensures that the repaired or replaced airbag control module interacts properly with your Pontiac Grand Am and restores full functionality of the safety system.
