What is a Saturn Vue FWD airbag control module?
The Saturn Vue FWD airbag control unit is the central safety unit that activates all occupant restraint systems in the event of a crash. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle, which is crucial for the vehicle's passive safety.
This SRS SDM (Sensing Diagnostic Module) records accident data using integrated sensors and controls the deployment of airbags and seat belt pretensioners.
It performs continuous self-diagnosis of the security system to detect faults at an early stage.
Why is the Saturn Vue FWD airbag control unit defective?
A Saturn Vue FWD airbag control unit often fails because it stores crash data after an accident, requiring a reset, or due to internal electronic errors that impair communication or functionality. Power surges or age-related wear and tear can also cause failure.
After an airbag deployment, the control unit stores crash data that prevents reuse without a professional reset.
Internal memory errors or communication problems within the module are also common causes of failure.
Water damage or extreme temperature fluctuations can irreparably damage the control unit's sensitive electronics, making a Saturn Vue FWD airbag control unit repair necessary.
Common error codes for Saturn Vue FWD airbag control unit repair
During Saturn Vue FWD airbag control module repair, specific error codes indicate internal control module issues such as communication problems, memory errors, or power supply problems. These B-codes directly indicate defects in the SRS module and require a precise diagnosis.
- B1000: Internal communication error – The control unit cannot communicate correctly with other systems.
- B1001: Internal Control Unit Error – A general functional error within the module itself.
- B1002: Airbag control module memory error – The module has problems with its internal data memory.
- B1003: Airbag control unit voltage supply faulty – The power supply to the control unit is unstable.
- B1004: Internal diagnostic error – The self-diagnosis function of the control unit is faulty.
- B1010: Airbag Control Module – Programming Memory Error – The module has problems with its program memory.
- B1030: Communication error between airbag control unit and other control units – The connection to other vehicle modules is interrupted.
- B1040: Seat occupancy detection – control unit not available – The module reports an error in the seat occupancy detection that affects the control unit.
- B1120: Control Module Internal Error – Crash Data Inaccessibility – Stored crash data is not readable or accessible.
- B1234: Faulty self-diagnosis function in the control unit – The control unit cannot correctly check its own functionality.
For accurate diagnosis and clearing of these codes, a GM-compliant airbag scan tool is essential to identify the specific cause of the errors.
Pure engine OBD scanners often provide no or incorrect information about the airbag control unit.
