What is a Chevrolet Equinox 3rd Gen airbag control module?
The Chevrolet Equinox 3rd Gen airbag control unit, known as the Sensing Diagnostic Module (SDM), is the vehicle's central safety unit. It continuously monitors all airbag sensors and, in the event of a collision, decides on the precise and timely deployment of the airbags and seatbelt pretensioners to ensure occupant safety.
This module, often referred to as the Airbag Computer Diagnostic Control Module, is essential for the proper functioning of the occupant restraint system. It performs diagnostic self-tests and stores important crash data and error codes.
Why is the Chevrolet Equinox 3rd Gen airbag control module defective?
A Chevrolet Equinox 3rd Gen airbag control unit often fails when it stores crash data during an accident and subsequently displays an error message that requires replacement or reset. Electronic damage caused by overvoltage or moisture can also lead to malfunction, compromising vehicle safety.
After a crash, the module stores irreversible data, making a reset or replacement mandatory. Internal electronic errors or age-related wear can also cause the control unit to stop functioning or report inconsistent errors.
Common error codes for Chevrolet Equinox 3rd Gen airbag control unit repair
When diagnosing a faulty Chevrolet Equinox 3rd Gen airbag control module, specific trouble codes will appear that indicate internal problems with the module. These codes are crucial for pinpointing the exact cause and distinguishing it from sensor or airbag component failures, allowing for targeted repair.
- B0013 → Driver Airbag Deployment Loop Stage 2 High Resistance → Error in the driver airbag control unit-related circuit.
- B1015 → Faulty airbag module → Internal defect in the airbag control unit itself.
- B1139 → Error within the SRS module → Internal functional error of the airbag control unit.
- B1193 → Airbag module related error → Error detected directly on the airbag control unit.
- B207F → SRS Unit Error → Specific error of the airbag control unit.

Installation and repair of the Chevrolet Equinox 3rd Gen airbag control unit
Installing a Chevrolet Equinox 3rd Gen airbag control unit requires the utmost precision and expertise, as it is a safety-critical component. After replacement, special programming or a reset to the vehicle's VIN is often necessary to fully reactivate the system and clear errors.
The control unit is typically mounted in the center console or driver's footwell. Before installation, the vehicle battery must be disconnected and a waiting period must be observed to eliminate any residual voltage.
After replacement, module coding or a reset using special diagnostic software is required to ensure functionality and erase all stored errors. For safety reasons, we recommend that this work be performed only by qualified personnel.
