Airbag control unit with part number 13543137

What does the airbag control unit 13543137 do?

Within the restraint system of Chevrolet, the airbag control unit 13543137 takes over central control. It evaluates the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners trigger, and monitors the entire system.

In doing so it reports faults via the airbag warning light, so that a faulty system in the car is immediately recognisable.

After an accident it stores crash data and locks itself.

Why does the control unit 13543137 fail?

In the 13543137, crash data stored after an accident is the most common cause, even if no airbag has deployed. An ordinary diagnostic tool cannot delete it. Other causes include ageing electronics, moisture and corrosion at plugs, cold solder joints, and voltage spikes from weak batteries or jump-starting.

Airbag24 deletes the crash data during the repair.

Ageing electronics and moisture are also typical reasons. Cold solder joints make themselves felt irregularly.

How can you tell that the 13543137 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, an error message may also appear, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may not deploy.

Even the warning light coming on is a reason to have the restraint system checked. An error message in the instrument cluster confirms the finding, and a failure to establish a connection with the diagnostic tool shows that communication is disturbed.
