Airbag control unit with part number 96654863

What does the airbag control unit 96654863 do?

The airbag control unit 96654863 forms the central control unit of the SRS restraint system for Chevrolet. It receives the signals from the crash sensors, determines the triggering of airbags and seatbelt pretensioners in an accident within milliseconds, and monitors the system continuously.

It shows faults via the airbag warning light in the instrument cluster. After an accident it stores crash data and locks itself.

The system works as a combination of sensors, control unit and triggering elements. If one link fails, the function of the whole suffers.

Why does the control unit 96654863 fail?

For 96654863 the most common cause is stored crash data after an accident, even without a triggered airbag. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A normal diagnostic tool cannot erase the crash data. Airbag24 takes over the erasure during the repair.

Aged components and cold solder joints impair the electronics gradually. Moisture and corrosion at plugs lead to transition resistances.

Voltage spikes arise, for example, from a weak battery or a jump start and stress the unit.

How can you tell that the 96654863 is defective?

A defect on the control unit 96654863 shows itself through several signs that you notice in the vehicle and on the diagnostic tool. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

These signs occur singly or in combination:

• Airbag warning light in the instrument cluster, permanently or intermittently
• Error message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory cannot be cleared

The warning light is a clear warning sign. Do not hesitate to have the fault checked.
