Airbag control unit with part number 9650136680

What does the airbag control unit 9650136680 do?

The airbag control unit 9650136680 is the central control unit of the restraint system (SRS) of Peugeot. It evaluates crash sensors, decides in a crash within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After a crash, it stores crash data and locks itself.

Monitoring also continues when the vehicle is parked with the ignition switched on. The unit checks sensors, wiring and activation and stores faults in the fault memory.

Faults are reported via the airbag warning light in the instrument cluster. If it stays off, no fault has been detected.

Why does the control unit 9650136680 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Other causes are aged electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes, for example from a weak battery or jump-starting.

Crash data cannot be deleted with a normal diagnostic tool. Airbag24 deletes it during the repair.

The other causes at a glance:

• Electronic components age and lose reliability over time.
• Cold solder joints can lead to intermittent contact.
• Moisture and corrosion at connectors disrupt signal transmission.
• Voltage spikes stress the electronics, for example with a weak battery or jump-starting.

How can you tell that the 9650136680 is defective?

A defect shows up on the airbag warning light in the instrument cluster, which is on permanently or intermittently. Also an error message in the instrument cluster, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

The warning light is the first visible sign of a fault. Anyone who watches it notices changes early.

In an emergency, airbags and seatbelt pretensioners may not trigger in the event of a defect. It is therefore advisable to have the fault memory read out promptly.
