What is a Saturn Aura Green Line airbag control unit?
The Saturn Aura Green Line 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, playing a crucial role in the safety of the vehicle's occupants.
This module, also known as the Sensing Diagnostic Module (SDM), uses sensors to detect the severity of an impact.
Based on this information, it triggers the appropriate airbags and seat belt pretensioners to minimize injuries.
Why is the Saturn Aura Green Line airbag control unit defective?
A Saturn Aura Green Line airbag control unit is often defective because it stores crash data after an accident and then becomes locked, or it suffers internal component damage due to aging and vibration, leading to malfunctions or a permanently illuminated airbag warning light. In these cases, a repair is often the most cost-effective solution.
After an airbag is deployed, the control unit stores indelible crash information, rendering it unusable without specialized repair and reset.
Internal electronic components can also fail due to age or overvoltages in the vehicle electrical system, leading to communication errors or a general loss of functionality.
Visible signs of a failure are often the permanently illuminated airbag warning light in the instrument cluster or stored error codes that indicate a lack of communication with the module.
Common error codes for Saturn Aura Green Line airbag control unit repair
Typical error codes for the Saturn Aura Green Line airbag control unit indicate internal module problems, communication issues, or malfunctions within the unit itself, which often require professional diagnosis and repair of the control unit. These codes are crucial for identifying the exact defect and restoring system safety.
- B1000 → Control unit communication error → The communication between the airbag module and the vehicle bus system is faulty or not present.
- B0050 → Airbag control unit internal error → There is an internal defect in the hardware or software of the airbag module.
- B0100 → Internal memory or logic error → Damage to the internal memory or processing logic of the control unit was detected.
- B0190 → MCU (Microcontroller Unit) Error → The central control unit (MCU) of the airbag module has failed or is malfunctioning.
- B2300 → Airbag control unit diagnostic error → The internal diagnostic system of the airbag module reports a general error or malfunction.
What part numbers are available for the Saturn Aura Green Line airbag control unit repair?
When repairing or replacing a Saturn Aura Green Line airbag control module, specific GM part numbers are critical to ensure compatibility and proper function in the vehicle. The most commonly validated OEM part numbers for this model are 15835185 and AU5WY79410.
These part numbers have been verified directly by General Motors (GM) and specifically for the airbag control unit (SRS SDM) of the Saturn Aura Green Line from 2007 to 2009.
The number 15835185 is a confirmed genuine GM part number, while AU5WY79410 is listed as an alternative OEM replacement number for the same module.
An exact match between the part number and the original part is crucial, as airbag control units are coded specifically for each vehicle and will only function reliably with the correct part numbers.
