Airbag control unit with part number 9677044380

What does the airbag control unit 9677044380 do?

The airbag control unit 9677044380 controls the restraint system (SRS) for Peugeot. It reads the crash sensors, calculates in the event of an accident within milliseconds which airbags and seatbelt pretensioners are to be triggered, and keeps a constant eye on the system. Faults appear via the airbag warning light.

During operation the unit continuously checks the connected components and stores any irregularities in the fault memory.

After an accident, it stores crash data and locks itself.

Why does the control unit 9677044380 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. An ordinary diagnostic tool does not clear it. Added to this are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Crash data cannot be cleared with a normal diagnostic tool. As long as it remains in memory, the finding stays in the control unit.

The other causes act over a longer period: electronics age, plug connections corrode, and voltage spikes from a weak battery or jump-starting put strain on the unit.

How can you tell that the 9677044380 is defective?

The airbag warning light in the instrument cluster stays on constantly or intermittently, and an error message appears. The diagnostic tool cannot establish a connection with the control unit, or the fault memory cannot be cleared. In an emergency, the airbags and seatbelt pretensioners could then possibly fail to trigger.

The warning light signals the defect as soon as it is present. A plug or a cable can also lie behind these signs, which is why only the fault memory clarifies the cause.
