Airbag control unit with part number 13589835

What does the airbag control unit 13589835 do?

As the control unit of the restraint system (SRS) of Chevrolet, the airbag control unit 13589835 controls the airbags and seatbelt pretensioners. It checks the signals from the crash sensors, decides on triggering within milliseconds in an accident, and monitors the system continuously.

Detected faults are reported via the airbag warning light. After an accident, it stores crash data and locks itself. The ongoing monitoring is meant to make faults recognisable early.

Why does the control unit 13589835 fail?

Most often the cause lies in crash data stored in the unit after an accident, even if no airbag was triggered. A normal diagnostic tool cannot erase it. Aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes also play a role.

What matters is the storage in the unit, not the triggering of an airbag. Airbag24 erases the crash data during the repair.

Aged electronics, cold solder joints, and moisture and corrosion on plug connections belong to the other possible causes.

Voltage spikes occur, for example, with a weak battery or a jump-start and can affect the electronics.

How can you tell that the 13589835 is defective?

The airbag warning light in the instrument cluster lighting up intermittently or constantly is the most visible sign. Accompanying it, an error message appears in the instrument cluster, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared.

As long as the defect exists, airbags and seatbelt pretensioners may not trigger in an emergency. Such an indication therefore requires attention.
