Airbag control unit with part number 9653441980

What does the airbag control unit 9653441980 do?

The airbag control unit 9653441980 is the central control unit of the restraint system (SRS) for Peugeot. It evaluates crash sensor signals and, in the event of an accident, decides within milliseconds which airbags and seatbelt pretensioners are triggered.

The unit monitors the system continuously and reports faults via the airbag warning light in the instrument cluster. This is how you find out when something is wrong in the restraint system.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 9653441980 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 plug connections, and voltage spikes.

Crash data cannot be erased with a standard diagnostic tool. Airbag24 erases it during the repair.

This list summarises the other causes:

• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or jump-starting
