Airbag control unit with part number 13505405

What does the airbag control unit 13505405 do?

The airbag control unit 13505405 controls the restraint system (SRS) of Chevrolet. In a crash it evaluates the crash sensors and triggers the appropriate airbags and seatbelt pretensioners within milliseconds.

It also monitors the entire system continuously. It detects faults and indicates them via the airbag warning light so that you can take action.

After an accident, the unit stores crash data and then locks itself.

Why does the control unit 13505405 fail?

The most frequent cause is crash data that remained stored after an accident, even if no airbag deployed. Added to this are aged components, cold solder joints, moisture at plugs and voltage spikes.

The possible causes in detail are:

• Crash data from an accident that remains in the memory
• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connectors
• Voltage spikes, for example from a weak battery or a jump start

A standard diagnostic tool cannot reach the crash data, which is why it remains.

How can you tell that the 13505405 is defective?

Typically the airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, a fault message appears there, the diagnostic tool cannot reach the control unit 13505405, and the fault memory cannot be erased.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy, even if the car otherwise appears unremarkable.
