Airbag control unit with part number 9676739380

What does the airbag control unit 9676739380 do?

The airbag control unit 9676739380 is the central unit of the restraint system in Peugeot vehicles. It processes the signals from the crash sensors, determines in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system permanently. It reports irregularities via the airbag warning light.

This includes checking the connections and triggering elements, which runs in the background.

After an accident it stores crash data and locks itself.

Why does the control unit 9676739380 fail?

The main cause with the 9676739380 is that crash data are stored after an accident, even without a deployed airbag; these data cannot be erased with a standard diagnostic tool. Aged electronics, cold solder joints, moisture and corrosion on plugs, and voltage spikes come on top.

Crash data are recorded events from the accident. At Airbag24 they are erased during the repair.

Aging of components and cold solder joints affect the reliability of the electronics.

Moisture or corrosion on plugs, as well as voltage spikes from a weak battery or a jump start, round off the picture.

How can you tell that the 9676739380 is defective?

The airbag warning light shows the fault on the 9676739380 as soon as it lights up permanently or intermittently. A fault message in the instrument cluster, a diagnostic tool without connection, or a fault memory that cannot be cleared point in the same direction. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

Have the warning light checked promptly, even if the vehicle drives normally.

The warning light is a clear indication that the system may be restricted.
