Airbag control unit with part number 9665944180

What does the airbag control unit 9665944180 do?

The airbag control unit 9665944180 coordinates the restraint system (SRS) in Peugeot vehicles. From the crash sensor signals it calculates within milliseconds in an impact which airbags and seatbelt pretensioners are triggered.

While driving, the unit checks the system for faults continuously. If it finds one, it indicates this via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself.

Why does the control unit 9665944180 fail?

With the 9665944180, stored crash data after an accident are the most common cause, even if no airbag has triggered. Aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes can likewise cause the failure.

Crash data cannot be erased with a normal diagnostic tool. They remain in the control unit until Airbag24 removes them during the repair.

Aged components and cold solder joints impair the function of the unit. Moisture and corrosion attack the contacts, and voltage spikes arise, for example, with a weak battery or when a jump start is used.

How can you tell that the 9665944180 is defective?

The airbag warning light on the 9665944180 lights up permanently or intermittently. Other signs include an error message in the instrument cluster, a diagnostic tool without connection to the control unit and a fault memory that cannot be erased. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The airbag warning light is the most important warning from the system. Do not ignore the light, because it signals that something is wrong in the restraint system.

Reading out the fault memory afterwards shows what lies behind it.
