Airbag control unit with part number 9650136880

What does the airbag control unit 9650136880 do?

The control unit 9650136880 is the switching centre of the airbag restraint system (SRS) at Peugeot. From the signals of the crash sensors it calculates within milliseconds which airbags and seatbelt pretensioners to trigger.

It also checks the system continuously for faults. If one is found, the airbag warning light shows it in the instrument cluster.

A crash means crash data is stored in the unit, and the unit then locks itself.

Why does the control unit 9650136880 fail?

The most common cause at the 9650136880 is crash data stored after an accident, even if no airbag fired. These cannot be removed with a normal diagnostic tool. Ageing components, cold solder joints, moisture on plug connectors and voltage spikes are also possible causes.

The crash data is erased during the repair by Airbag24. The other causes cannot be narrowed down without a check, which is why checking the components is part of the repair.

Voltage spikes arise, for example, from a weak battery or after a jump start and put strain on the electronics.

How can you tell that the 9650136880 is defective?

The airbag warning light in the instrument cluster lights up on the 9650136880 permanently or intermittently, and a fault message appears in the instrument cluster. The diagnostic tool makes no connection to the control unit. In an emergency, airbags and seatbelt pretensioners may not fire.

In addition, the fault memory cannot be cleared.

Even intermittent lighting is one of the signs that justify a check.
