What is a Saturn Vue AWD airbag control module?
The Saturn Vue AWD 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, which is essential for safe driving.
This module, also called SRS SDM (Supplemental Restraint System Sensing Diagnostic Module), is crucial to the functionality of your airbag system.
It coordinates the deployment of front and side airbags as well as the seat belt tensioners to provide optimal protection for the occupants.
Why is the Saturn Vue AWD airbag control unit defective?
A Saturn Vue AWD airbag control unit often malfunctions because it stores crash data after an accident that requires reprogramming, or because internal components fail due to aging, moisture, or electrical surges. This often leads to the airbag warning light being permanently activated.
After a vehicle crash, the control unit stores accident data in the EEPROM memory, which makes a professional reset essential.
Electronic errors in the module itself, such as cold solder joints or chip defects, can also lead to failure.
Common error codes for Saturn Vue AWD airbag control unit repair
During Saturn Vue AWD airbag control module repair, specific error codes may occur that indicate problems with the module itself or its communication, requiring a precise diagnosis. These codes are crucial for identifying and correcting the cause of the error.
- B1000 → Control unit communication error → The airbag control unit cannot communicate correctly with other vehicle systems.
- B0051 → Airbag control unit crash data memory → Accident data is stored in the EEPROM of the control unit after a crash, which requires a reset.
- B0058 → Seat belt pretensioner circuit fault → A problem in the passenger seat belt pretensioner circuit is diagnosed and indicated by the airbag control unit.
These error codes are typical for defects in the airbag control unit and can only be read with special diagnostic devices.
A correct diagnosis is the first step to successful repair and restoration of vehicle safety.
What part numbers are available for the Saturn Vue AWD airbag control unit repair?
For Saturn Vue AWD airbag control unit repairs, there are specific GM OEM part numbers that ensure compatibility with your vehicle model. These numbers are crucial for identifying the correct replacement or repair part for a successful repair.
The most common OEM part numbers for the Saturn Vue AWD airbag control module are:
- 22717049 (GM Original OEM)
- 22718158 (GM Original OEM, alternative number)
- 25865978 (GM Original OEM, Airbag Sensing and Diagnostic Module)
It is critical to match the existing part number of your defective module to ensure proper fit and function.
Other manufacturers such as Bosch or Continental do not offer direct 1:1 matching OEM part numbers for this specific Saturn module.
Saturn Vue AWD Airbag Control Unit: Compatibility & Years
The Saturn Vue AWD airbag control unit is specifically designed for Saturn Vue all-wheel drive models from 2005 to 2010. Careful verification of the part number is essential for complete compatibility. VIN-specific programming is always required for proper function.
The main compatibility extends to Saturn Vue AWD vehicles of the model years 2005, 2006, 2007, 2008, 2009 and 2010.
In some cases, the module may also be relevant for later model years up to 2012, which requires a detailed comparison of the part number.
Functionality and features of the Saturn Vue AWD airbag control unit
The Saturn Vue AWD airbag control unit collects accident data via a network of sensors and, in the event of a crash, activates airbags and seatbelt pretensioners in a timely manner to provide optimal occupant protection. It also continuously diagnoses the status of the safety systems, stores relevant data, and enables precise monitoring.
The module controls several airbag firing circuits, including front and side airbags and seat belt pretensioners.
It continuously monitors all connected sensors and circuits for malfunctions and stores them for diagnosis.
After an accident, the crash data stored in the EEPROM must be erased and the module often reprogrammed to the vehicle VIN.
Installation position and special features of the Saturn Vue AWD airbag control unit
The Saturn Vue AWD airbag control unit is typically mounted in the vehicle floor area under the seat or in the center console and requires special safety measures such as disconnecting the battery during installation or removal. A professional crash data reset and VIN matching are essential after a repair.
The module is connected to the vehicle CAN bus and the sensor and airbag cables via a multi-pin connector.
Before removing or repairing the vehicle, it is essential to disconnect the vehicle battery and wait at least one minute.
A "well-tested" used control unit can be fully functional again after a professional reset and, if necessary, chip programming.
