Airbag control unit with part number 9801522880

What does the airbag control unit 9801522880 do?

The airbag control unit 9801522880 is the central control unit of the restraint system (SRS) of Peugeot. It evaluates the signals from the crash sensors and decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered.

In addition, it monitors the system continuously and shows faults via the airbag warning light in the instrument cluster. Without a working control unit, the restraint system cannot perform its task in an emergency.

After an accident the unit stores crash data and then locks itself. The manufacturer number Bosch 0285011279 is also printed on the housing.

Why does the control unit 9801522880 fail?

Most often the cause is crash data stored after an accident, even if no airbag was triggered, and a normal diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Voltage spikes occur, for example, with a weak battery or a jump start and strain the electronics. Aged components, cold solder joints and corrosion cannot be reliably detected from outside, which is why only the read-out fault memory provides clarity.

How can you tell that the 9801522880 is defective?

A defect shows itself in the airbag warning light, which stays on permanently or intermittently. In addition there is a fault message in the instrument cluster, a diagnostic tool with no connection to the control unit, and a fault memory that cannot be cleared.

These signs occur in detail:

• The airbag warning light stays on permanently or intermittently.
• A fault message appears in the instrument cluster.
• The diagnostic tool finds no connection to the control unit.
• The fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. The warning light shows the defect, so a prompt check makes sense.
