Airbag control unit with part number 1376421080

What does the airbag control unit 1376421080 do?

For Peugeot, the airbag control unit 1376421080 controls the restraint system (SRS). In an accident, it evaluates the crash sensors and determines within a fraction of a second which airbags and seatbelt pretensioners fire. In normal operation, it monitors the system and reports faults via the airbag warning light.

After an accident, the unit writes crash data and locks itself. Only the repair lifts the lock.

The fault memory records which faults the unit has detected during operation.

Why does the control unit 1376421080 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Ageing electronics, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes can also lead to failure.

• Ageing electronic components
• Cold solder joints on the circuit board
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or a jump start

Crash data cannot be removed with a standard diagnostic tool. Airbag24 erases it during the repair.

What is causing the failure in an individual case is determined by the test on the unit.

How can you tell that the 1376421080 is defective?

A defect is recognised mainly by the airbag warning light, which stays on permanently or lights up intermittently. Error messages in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared may also occur. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

• Airbag warning light on, permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool cannot establish a connection to the control unit
• Fault memory cannot be cleared

Seen from the vehicle, the warning light is the first thing that stands out. It calls for a check, even if the car otherwise drives normally.
