Chevrolet Blazer EV airbag control unit repair⁽¹⁾

What should you know about Chevrolet Blazer EV airbag control units?

The airbag control unit in the Chevrolet Blazer EV evaluates the signals from the crash sensors, controls the triggering of the airbags and belt tensioners, and monitors the entire restraint system. A detected fault is shown by the airbag warning light. After an accident, the control unit stores crash data and locks itself.

The control unit is the central unit of the airbag system. Based on the sensor data, it decides whether and when the restraint systems are triggered. Because the system is safety-relevant, faults should be checked promptly by a specialist workshop. A malfunction can affect the entire system.

Airbag24 repairs the airbag control unit that you send in. Do not work on the airbag system yourself. If you cannot remove the control unit safely on your own, have a specialist workshop carry out the removal.

Which Chevrolet Blazer EV generations are there?

The Chevrolet Blazer EV has been built in its 1st generation since 2024, and production is still ongoing. For the airbag control unit, the year of manufacture also matters, because software and hardware versions can change during the production period.

• 1st generation (since 2024) – current generation, production still ongoing.

Which version is installed in your vehicle can be determined from the label on the control unit and from the vehicle identification number (VIN). The next section explains how to proceed.

How do I identify my Chevrolet Blazer EV airbag control unit?

The part number on the label of the control unit determines the exact version. Together with the year of manufacture and the vehicle identification number (VIN), the unit can be clearly assigned. A fault code alone does not prove a defect in the control unit.

Before sending the unit in, note the part number from the housing as well as the year of manufacture and the VIN of your vehicle. These details make it possible to check the version your vehicle actually has installed.

The fault memory may show codes such as B1000 (internal performance fault of the airbag control unit), B0012 (ignition circuit stage 1 of the driver steering wheel airbag faulty) and B0052 (deployment commanded, restraint systems fired, crash record stored). They help narrow down the cause, but on their own they do not prove that the control unit is defective. Only reading out and testing the unit shows whether it is affected.

What airbag equipment does the Chevrolet Blazer EV have?

According to the owner's manual, the Chevrolet Blazer EV has frontal airbags for driver and front passenger, knee airbags, seat-mounted side airbags and head airbags along the side windows. The exact equipment depends on the year of manufacture and trim level.

The driver's frontal airbag sits in the centre of the steering wheel, the front passenger's frontal airbag in the instrument panel on the passenger side. The knee airbags are located below the steering column and below the glove box. The seat-mounted side airbags are integrated into the seatbacks on the door side, and the roof-rail head airbags run in the roof lining above the side windows. Which seat rows the head airbags cover can be found in the owner's manual for your model year.

This is how your control unit gets repaired: first have the fault memory read out. Then disconnect the battery and remove the control unit. Next, create an online repair request and send the unit to Airbag24. Processing usually takes 3–4 working days (checking, repairing, testing). The repaired control unit returns with all vehicle data and is ready for use immediately after reinstallation — no coding or programming is required.
