What is a Saturn Ion Sedan airbag control module?
The Saturn Ion Sedan airbag control unit is the central safety unit in your vehicle, activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores important crash data, and ensures the proper functioning of the entire airbag system for your safety.
This SRS SDM (Sensing Diagnostic Module) analyzes signals from crash sensors in real time to accurately detect a collision.
It is specifically designed for Saturn Ion Sedan models from 2003 to 2007 and must exactly match the vehicle model.
The module also performs continuous self-diagnosis and stores any error codes that indicate problems in the system.
Why is the Saturn Ion Sedan airbag control unit defective?
The Saturn Ion Sedan airbag control module may be defective because it was deployed after an accident, is experiencing internal malfunctions, or has been damaged by moisture. A defective module compromises safety and must be repaired or replaced for the airbag systems to function properly.
A common reason for failure is the storage of crash data after an airbag deployment, which requires a targeted Saturn Ion Sedan airbag control unit repair or reset.
Internal electronic defects or moisture ingress, often due to installation positions under the seat, can also lead to module failure.
Age-related wear and tear on the control unit components can also cause the system to stop functioning or malfunction.
Common error codes for Saturn Ion Sedan airbag control unit repair
During Saturn Ion Sedan airbag control module repair, specific error codes may occur that indicate problems with the module itself. The most common are B0081, which signals an internal communication error within the control module, and B0092, which indicates a problem with the passenger sensing system.
- B0081 → Control unit error/LAN communication error with symptom code 71 → This code indicates an internal communication error of the airbag control module (SDM).
- B0092 → Control Unit Error / Passenger Presence System 1 Performance → This code is related to the passenger detection system (PPS) of the control unit and signals a malfunction.
These error codes are directly attributable to the airbag control unit and are not generated by external sensors or belt tensioners.
A precise diagnosis with a suitable scanner is essential to find the exact cause of the fault and initiate the correct Saturn Ion Sedan airbag control unit repair.
What part numbers are available for the Saturn Ion Sedan airbag control unit repair?
Several specific OEM part numbers are relevant for the Saturn Ion Sedan airbag control unit repair, ensuring exact fit and function for models from 2003 to 2007. These numbers are crucial for selecting the correct replacement or repair module.
- 22725728 – GM / Delphi OEM
- 21998560 – GM / Delphi OEM (alternative number)
- 09397452 – GM / Delphi OEM
These listed part numbers are 100% verified and have been specifically confirmed for the Saturn Ion Sedan Airbag Control Module.
It is critical to accurately match the number on your original part before repairing or replacing to ensure compatibility.
Modules from other manufacturers such as Bosch or Continental do not have publicly listed OEM part numbers for this specific model that can be safely accessed.
After replacing an airbag control unit, programming to the vehicle VIN by a specialist workshop is usually required to ensure full functionality.
