Airbag control unit with part number 618294300

What does the airbag control unit 618294300 do?

The airbag control unit 618294300 is the control unit of the SRS restraint system for Peugeot. It evaluates the crash sensors, determines the triggering of airbags and seatbelt pretensioners within milliseconds in an accident, and monitors the system continuously. If it detects a fault, this appears via the airbag warning light.

After an accident, the unit stores crash data and locks itself.

The control unit works in the background during every journey and checks its connections as it does so.

Why does the control unit 618294300 fail?

The most common cause is crash data on the 618294300 that remains in the unit after an accident, even if no airbag fired; a normal diagnostic tool cannot erase it. Further causes are aged electronics, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

Crash data stays in the memory until Airbag24 removes it. Before the repair, it therefore stays in the unit.

Electronic components age, solder joints can go cold, and moisture or corrosion attacks connections. Voltage spikes arise, for example, with a weak battery or jump-starting.

How can you tell that the 618294300 is defective?

A defect is indicated by the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In the instrument cluster, an error message also appears, and the diagnostic tool does not connect to the control unit 618294300.

The fault memory cannot be cleared, which likewise indicates a fault. In an emergency, airbags and seatbelt pretensioners may therefore not be able to deploy.

Have the warning light checked promptly as soon as it appears.
