Airbag control unit with part number 603201500

What does the airbag control unit 603201500 do?

The airbag control unit 603201500 is the central control unit of the restraint system (SRS) for Peugeot and Citroën. It evaluates the signals from the crash sensors and in a collision decides in an instant which airbags and seatbelt pretensioners are triggered.

It also monitors the entire system during operation. If it detects a fault, it reports this via the airbag warning light in the instrument cluster.

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

Why does the control unit 603201500 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered; a standard diagnostic tool cannot erase it. Also possible are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

The fact that no airbag was triggered therefore does not mean the unit has stored nothing. The crash data remain in the control unit until they are removed during a repair.

The other causes concern the condition of the electronics and their surroundings. Which of them applies only becomes clear when the unit is examined.

How can you tell that the 603201500 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently; in addition there may be an error message in the instrument cluster, the diagnostic tool may be unable to connect, or a fault memory that cannot be cleared may be present. In that state, airbags and seatbelt pretensioners may not be able to trigger in an emergency.

The light is the clearest sign that something in the system is wrong. A light that burns permanently calls for a check without delay.

Even a warning that appears only intermittently is reason enough to have the fault memory read out.
