Airbag control unit with part number 9673393980

What does the airbag control unit 9673393980 do?

Control of the restraint system (SRS) at Peugeot rests with the airbag control unit 9673393980. It evaluates the crash sensors and determines in a collision within milliseconds which airbags and seatbelt pretensioners fire.

The unit continuously checks the components of the system. If it detects a fault, it displays this via the airbag warning light in the instrument cluster.

In a collision the unit stores crash data and then locks itself. This belongs to its task in the restraint system.

Why does the control unit 9673393980 fail?

Crash data from an earlier accident is the most common cause, even if no airbag was deployed at all; a normal diagnostic tool cannot erase it. Other causes in control unit 9673393980 are aged electronics, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Stored crash data does not necessarily mean component damage, but it does complicate diagnosis. Airbag24 removes it during the repair.

The other causes arise from ageing, moisture and electrical load. Solder joints and plug connections react sensitively, and voltage spikes occur, for example, with a weak battery or a jump start.

How can you tell that the 9673393980 is defective?

A defect in control unit 9673393980 shows itself through the airbag warning light, through messages in the instrument cluster and through a diagnostic tool that finds no contact. In this case, airbags and seatbelt pretensioners may not be able to deploy in an emergency.

Watch for these signs:

• airbag warning light that stays on permanently or intermittently
• fault message in the instrument cluster
• no connection to the diagnostic tool
• fault memory that cannot be cleared

If you notice one of these signs, the fault memory is the right next step. It shows the finding, not merely the symptom.
