4.8What is a Citroën C5 Aircross II airbag control unit?
In the Citroën C5 Aircross II, the airbag control unit is the central control unit of the restraint system (SRS). In an accident, it decides within milliseconds, based on the crash sensors, which airbags and seatbelt pretensioners deploy. In normal operation it constantly checks the system and reports faults via the airbag warning light.
The control unit is installed in the Citroën C5 Aircross II (since 2025). It works unobtrusively in the background. Usually it only draws attention when the airbag warning light comes on. After an accident it stores crash data and locks itself.
All information from the restraint system comes together here. If the warning light is on, a check of the unit is the next step to narrow down the cause of the fault.
Why is the Citroën C5 Aircross II airbag control unit defective?
The most common cause is crash data stored after an accident, even if no airbag deployed. A normal diagnostic tool cannot erase it. Other causes are aged components, cold solder joints, moisture and voltage spikes.
Aged electronic components and cold solder joints develop gradually. Moisture and corrosion on connectors disturb the signals. Voltage spikes, for example from a weak battery or a jump start, can damage the electronics.
Typical signs: the airbag warning light stays on permanently. The fault memory cannot be cleared. The diagnostic tool cannot connect to the control unit. Do not ignore the warning light, because with a fault, deployment in an emergency is not ensured.
Common error codes for Citroën C5 Aircross II airbag control unit repair
The error codes in the Citroën C5 Aircross II indicate internal faults of the control unit, communication faults, problems with the supply voltage and faults in the squib circuits of the airbags. They are read out with a diagnostic tool.
The following list shows codes that can occur with this control unit.
- F620 → Internal fault in the control unit, not specified further
- F633 → Internal fault in the front passenger airbag firing system
- F00F → Control unit no longer transmits on the CAN network
- E650 → Control unit supply voltage too high
- B0001 → Driver airbag squib circuit: resistance too high
- B0028 11 → Front right side airbag: wiring fault, short circuit to ground
- C601 → Open circuit in the driver airbag squib circuit
A code alone does not reliably show that the control unit is defective. Connectors, wiring or an airbag module can also be the cause. Only the check will clarify it.
What part numbers are available for the Citroën C5 Aircross II airbag control unit repair?
The part number is on the label of the airbag control unit. It determines the exact version, because within the Citroën C5 Aircross II model series there are different numbers depending on equipment and year of manufacture.
We do not currently have any part numbers for this vehicle. Read the number from the label of your unit and enter it in the repair order. It only ensures that it is the right unit; whether it is defective is shown only by reading out the fault memory or by the check.
This is how you get to the repair: have the fault memory read out, disconnect the battery and remove the control unit. Then create a repair order online and send in the unit. Processing at Airbag24, with checking, repairing and testing, usually takes 3–4 working days. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
