Chevrolet Equinox EV 1st generation airbag control unit repair

What is a Chevrolet Equinox EV 1st generation airbag control unit?

In the Chevrolet Equinox EV 1st generation (since 2024), the airbag control unit works as the central unit of the restraint system (SRS). It reads the signals from the crash sensors and, in an accident, decides within milliseconds which airbags and which seatbelt pretensioners fire.

The crash sensors of your Chevrolet report decelerations and accelerations. The control unit evaluates these readings before the occupants even properly feel the impact. It also stays active in everyday driving: it continuously checks the entire system and indicates faults via the airbag warning light.

If it has registered an accident, it stores crash data and locks itself. The warning light in the instrument cluster then tells you that the system is not ready for operation. Until the unit is repaired, your Chevrolet lacks the protection of the restraint system in an emergency.

Why is the Chevrolet Equinox EV 1st generation airbag control unit defective?

An accident is the most common cause: crash data stored during it remains in the unit even if no airbag has deployed. Other possible causes include aged electronic components, cold solder joints, moisture and corrosion on connectors, or voltage spikes.

Such crash data cannot be removed with an ordinary diagnostic tool. That is why a control unit can remain locked even though the airbags are intact and there is barely anything to see on the vehicle from the outside.

Even without an accident, time takes its toll on the components: electronics age, solder joints turn cold, and contacts then work only intermittently. If moisture gets in or the connectors corrode, the signals get mixed up. Voltage spikes, for example with a weak battery or after a jump start, put additional strain on the circuit.

A defect usually becomes noticeable like this: the airbag warning light stays on permanently, the fault memory cannot be reset, or the diagnostic tool cannot access the control unit. If your Chevrolet shows one of these signs, you should have the unit checked.

Common error codes for Chevrolet Equinox EV 1st generation airbag control unit repair

An error code points to a specific area of the system: to internal faults of the control unit, to the configuration, to the firing circuits of the front airbags, or to a stored crash data record.

With this vehicle, the following codes occur among others, each with a brief explanation of which area is affected:

• B1000 → Internal performance fault of the airbag control unit
• B1001 → Option configuration error, data does not match
• B1019 → Configuration mismatch in the number of restraint components
• B0052 → Deployment commanded, crash data record stored
• B0012 → Driver steering wheel airbag, stage one firing circuit faulty
• B0013 → Driver steering wheel airbag, stage two firing circuit faulty
• B0019 → Passenger dashboard airbag, stage one firing circuit faulty
• B0020 → Passenger dashboard airbag, stage two firing circuit faulty

You start clarifying the problem by reading out the fault memory with a diagnostic tool. However, the code only names the area, not necessarily the cause: a connector, a wire or an airbag module can be behind it just as well as the control unit itself. Only the inspection shows where the fault lies. Note down the codes you have read out before you remove the unit.

What part numbers are available for the Chevrolet Equinox EV 1st generation airbag control unit repair?

On the label of your removed control unit you will find the part number, which defines the exact version. Depending on equipment and year of manufacture, the numbers differ within a model series.

Copy the number from the label into the repair order. This allows us to assign your unit unambiguously. Whether it is actually defective is decided not by the number but by reading out the fault memory and the inspection at Airbag24.

Proceed as follows: have the fault memory read out, disconnect the battery and remove the control unit. Then create a repair order online and send in the unit. Inspecting, repairing and testing usually take 3–4 working days with us. Afterwards you receive your own control unit back.

The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
