Airbag control unit with part number 602327200

What does the airbag control unit 602327200 do?

The airbag control unit 602327200 controls the restraint system (SRS) of Peugeot. It evaluates signals from the crash sensors, decides within milliseconds in an impact whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. Faults are reported via the airbag warning light.

The decision is made by the unit itself, without any involvement from the driver. It measures continuously whether the system is ready.

After an accident, the unit stores crash data and locks itself. It is the repair that ends this lock.

Why does the control unit 602327200 fail?

Stored crash data is the most common cause for 602327200, and this applies even when no airbag has deployed. Added to this are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes from a weak battery or jump-starting.

Crash data remains stored in the unit after an accident. A normal diagnostic tool cannot erase it, so reading the fault alone does not solve the problem.

The other causes concern the electronics and their connections. Solder joints and components can cause faults over time, while moisture and corrosion disturb the contact at plugs.

Voltage spikes arise, for example, from a weak battery or from starting with jump-start cables, and they place additional strain on the electronics. Airbag24 erases the crash data during the repair.

How can you tell that the 602327200 is defective?

The airbag warning light in the instrument cluster lights up on 602327200 permanently or intermittently. This is accompanied by an error message in the instrument cluster, a missing connection to the diagnostic tool, and a fault memory that cannot be cleared.

If the control unit is defective, airbags and seatbelt pretensioners may not be able to deploy in an emergency. This sign must therefore not be ignored, even if the vehicle is still running.
