Airbag control unit with part number 9802958480

What does the airbag control unit 9802958480 do?

The airbag control unit 9802958480 coordinates the restraint system (SRS) in Peugeot. It receives the signals from the crash sensors, decides within milliseconds in an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It shows faults via the airbag warning light.

During operation every component is checked. Deviations end up in the fault memory, which a diagnostic tool can read out.

After an accident, the unit stores crash data and locks itself. It is therefore the memory for accident data.

Why does the control unit 9802958480 fail?

Most often the cause is crash data stored after an accident, even without an airbag having been triggered. Ordinary diagnostic tools do not clear it from the memory. Other causes are ageing, cold solder joints, moisture and corrosion, and voltage spikes.

• Ageing of electronic components
• Cold solder joints
• Moisture and corrosion at plug connectors
• Voltage spikes from a weak battery or jump-starting

Which cause applies in the individual case is clarified by an examination of the unit and the fault memory.

How can you tell that the 9802958480 is defective?

A defect becomes visible in the vehicle, through several signs at once or individually. The most obvious sign is the airbag warning light in the instrument cluster, which stays on permanently or intermittently. In a crash, airbags and seatbelt pretensioners may then possibly not trigger.

• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

Signs like these are warnings from the system itself and not a trivial matter.
