Airbag control unit with part number 9802958880

What does the airbag control unit 9802958880 do?

The airbag control unit 9802958880 controls the restraint system (SRS) of Peugeot. In a collision it evaluates the crash sensors and decides within milliseconds whether the airbags and seatbelt pretensioners are triggered.

The unit also monitors all components of the system. Faults that occur are shown via the airbag warning light.

After an accident it stores crash data and locks itself. This characteristic applies to every way of handling the unit.

Why does the control unit 9802958880 fail?

The most common cause is crash data stored after an accident, even if no airbag was deployed. A normal diagnostic tool does not erase them. Ageing components, cold solder joints, moisture, corrosion and voltage spikes can also be the cause.

The further causes include mainly:

• ageing electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 9802958880 is defective?

A defect becomes visible through the airbag warning light in the instrument cluster, which stays on permanently or intermittently. In addition there is an error message and no connection between the diagnostic tool and the control unit. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

An fault memory that cannot be cleared is also one of the signs. In this case the warning light is the signal you should watch for.
