Airbag control unit with part number 13575448

What does the airbag control unit 13575448 do?

The airbag control unit 13575448 runs the restraint system (SRS) in vehicles from Chevrolet. In a crash it evaluates the signals from the crash sensors and decides which airbags and seatbelt pretensioners are triggered. It reports faults via the airbag warning light.

The unit works throughout the entire journey and checks the sensors continuously. In doing so it records every irregularity, which ends up in the fault memory.

After an accident the unit stores crash data and locks itself. The crash data remains in the control unit as an event log.

Why does the control unit 13575448 fail?

The most common cause is that crash data was stored after an accident, even if no airbag has deployed. Other causes are ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The stored data cannot be removed with a standard diagnostic tool, and so the fault remains in the unit.

The other causes tend to develop gradually. Ageing components, cold solder joints and corrosion change the connections over time, while a weak battery or jump-starting can briefly produce high voltages. Only the fault memory shows which cause is present.

How can you tell that the 13575448 is defective?

A defect shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there is an error message in the instrument cluster, a diagnostic tool without connection to the control unit, and a fault memory that cannot be cleared.

The warning light is the most important warning sign, because it notices every detected fault and displays it. If it stays on after starting, have the system checked promptly.

While a defect persists, airbags and seatbelt pretensioners may not trigger in an emergency. For this reason, checking the system takes priority.
