Airbag control unit with part number 96406714

What does the airbag control unit 96406714 do?

The airbag control unit 96406714 coordinates the restraint system (SRS) in Daewoo and Chevrolet. From the values of the crash sensors, it determines whether a crash requires the airbags and seatbelt pretensioners to deploy.

The unit works throughout the entire journey and monitors the system continuously. If it detects a fault, the airbag warning light in the instrument cluster lights up.

After a crash, the unit stores crash data and locks itself.

Why does the control unit 96406714 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Other causes include aged components, cold solder joints, corrosion at plug connectors and voltage spikes.

Stored crash data cannot be erased with a standard diagnostic tool. The test shows which of the other causes applies:

• aged electronic components whose function is declining
• cold solder joints on the circuit board
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or a jump start

The list gives an overview of typical causes, not a diagnosis.

How can you tell that the 96406714 is defective?

A defect shows up as the airbag warning light in the instrument cluster staying on permanently or intermittently, as an error message in the instrument cluster, and as a diagnostic tool that cannot connect to the control unit. A fault memory that cannot be cleared also points to it.

The warning light in particular is an important sign, because it indicates the fault for as long as the fault exists. In an emergency, airbags and seatbelt pretensioners may then fail to deploy. Have such a warning checked promptly.
