What is a Chevrolet Trax 2nd Gen airbag control module?
The Chevrolet Trax 2nd Gen airbag control unit is your vehicle's central safety unit, activating all occupant restraint systems in the event of an accident. It precisely monitors sensors, stores important crash data, and ensures the proper functioning of all airbag modules and seatbelt pretensioners to maximize your safety.
This SRS (Supplemental Restraint System) SDM (Sensing Diagnostic Module) is the heart of the passive safety system. It receives signals from impact sensors and makes lightning-fast decisions about the necessary protective measures.
The modules are VIN-linked and must be specifically programmed to your vehicle after a replacement or accident to ensure correct operation.
Why is the Chevrolet Trax 2nd Gen airbag control unit defective?
The Chevrolet Trax 2nd Gen airbag control unit often fails after an accident or due to internal malfunctions, such as crash data being permanently stored or internal components being damaged. This causes the airbag warning light to illuminate and the system to no longer function properly in an emergency, necessitating prompt repair or replacement.
After an accident, these modules store so-called "crash data" or "hard codes" that require the unit to be reset.
Even without an accident, the control unit can develop internal memory errors (EEPROM), communication problems or hardware defects that cause a failure.
Typical symptoms include a permanently illuminated airbag warning light or specific error codes that point to the module itself.
Common error codes for Chevrolet Trax 2nd Gen airbag control unit repair
When diagnosing a faulty Chevrolet Trax 2nd Gen airbag control module, specific B-codes will occur, signaling internal errors or communication problems with the module. These error codes require specialized repair, reset, or replacement of the control module because they directly affect its functionality.
- B1000 → Control unit communication error → Internal communication problem or incorrect programming.
- B1001 → Airbag control module power supply voltage too low or too high → Problems with the vehicle battery or the power supply to the module.
- B1002 → Internal memory error in the airbag control unit → Defect in the internal memory of the control unit (e.g. EEPROM error).
- B1010 → Airbag ECU self-test error → The control unit cannot pass its own system check.
- B1015 → Airbag control unit initialization error → Module cannot be initialized properly at startup.
- B1020 → EEPROM error (control unit memory module) → Damage to the non-volatile memory, often after a crash.
- B1030 → Software error in the airbag control unit → Corrupt or incompatible software in the module.
- B1050 → Airbag control unit hardware error → Physical damage or defect in the control unit hardware.

The service allows you to keep the OEM module, which fits perfectly with your Chevrolet Trax 2nd Gen and does not require laborious programming at the workshop, provided there is no hardware damage.
A reset is a proven method to deactivate the airbag warning light and restore full functionality of the safety system after a diagnosis.
Fitting and installation of the Chevrolet Trax 2nd Gen airbag control unit
Installation of the Chevrolet Trax 2nd Gen airbag control unit requires special safety precautions and is usually performed in the footwell under the center console. Before beginning the repair, it is imperative to disconnect the vehicle's battery and wait at least two minutes to prevent accidental airbag deployment.
The control unit is usually attached to the vehicle floor with three screws and is connected to the wiring harness via yellow safety connectors.
After physical installation, the control unit must be coded to the vehicle identification number (VIN) of your Chevrolet Trax 2nd Gen by a specialist workshop using special diagnostic software.
Correct installation and subsequent programming are crucial for the reliable function of the airbag system and the safety of the occupants after repair.
