Airbag control unit with part number 96420753

What does the airbag control unit 96420753 do?

The airbag control unit 96420753 is the restraint system (SRS) control unit in Chevrolet vehicles. It checks the signals from the crash sensors, decides within milliseconds in an accident which airbags and seatbelt pretensioners fire, and reports faults via the airbag warning light.

Between accidents the unit works in the background and monitors the system. After an accident it stores crash data and locks itself.

Why does the control unit 96420753 fail?

The most common cause lies in crash data from an accident, even if no airbag was triggered. Added to this are aged electronics, cold solder joints, moisture and corrosion on connectors, and voltage peaks.

Other causes at a glance:

• aged electronic components
• cold solder joints
• moisture and corrosion on plug connections
• voltage peaks from a weak battery or a jump start

A normal diagnostic tool gives no access that would allow the crash data to be removed.

How can you tell that the 96420753 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, 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. Airbags and seatbelt pretensioners may then fail to trigger in an emergency.

The warning light is the most visible sign, so act on it promptly. A check with the diagnostic tool shows what is present in the control unit.
