4.8What is an Peugeot 306 Cabriolet I airbag control unit?
The Peugeot 306 Cabriolet I airbag control unit is the central control unit of the restraint system (SRS). It evaluates the signals from the crash sensors, decides within milliseconds in an accident whether to deploy the airbags and seatbelt pretensioners, and continuously monitors the system.
In the interplay of sensors, control unit and airbags, the sensors supply the measured values, the control unit evaluates them and enables the firing of the appropriate restraint devices. The control unit is fitted in the Peugeot 306 Cabriolet I (1994 to 2002).
If the control unit detects a fault during its ongoing self-test, it reports it via the airbag warning light in the instrument cluster. After an accident it stores crash data and locks itself.
Why is the Peugeot 306 Cabriolet I airbag control unit defective?
The most common cause is crash data stored after an accident, even if no airbag deployed. Other causes are aged electronic components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.
Stored crash data cannot be cleared with an ordinary diagnostic tool. The control unit then stays locked, even though the airbags themselves may be undamaged.
Voltage spikes occur, for example, with a weak battery or when jump-starting. Over time, components on the circuit board also age and solder joints become brittle. Typical signs: the airbag warning light stays on permanently, the fault memory cannot be cleared, or the diagnostic tool cannot connect to the control unit.
Common error codes for Peugeot 306 Cabriolet I airbag control unit repair
The error codes of the Peugeot 306 Cabriolet I airbag control unit show whether there is a communication fault, an internal control unit fault or a problem in a squib circuit. Stored crash data is also reported through codes.
The following list shows codes that occur frequently on this vehicle and may make a repair necessary.
- 9650 → Airbag system fault, to be clarified by diagnosis
- B1000 → General fault in the restraint system
- B1001 → Restraint system fault, exact cause unknown
- B1004 → Airbag system malfunction
- B1010 → Restraint system malfunction
- B1020 → Internal fault of the airbag control unit
- B1030 → Airbag system malfunction
- B1040 → Restraint system malfunction
- B1050 → Airbag system fault, to be clarified by diagnosis
- B1060 → Restraint system malfunction
Error codes are read out with a diagnostic tool. A code alone does not reliably show that the control unit is defective, because connectors, wiring or an airbag module can also be the cause. Only an inspection shows where the fault lies.
What part numbers are available for the Peugeot 306 Cabriolet I airbag control unit repair?
The part number is on the label of the control unit and determines the exact version. Within a model series there are different numbers depending on equipment and year of manufacture.
The following list contains known part numbers for the Peugeot 306 Cabriolet I; it makes no claim to completeness.

Compare the number on your own unit with this list. This only ensures that it is the right unit. Whether it is defective is only shown by reading out the fault memory or by the inspection.
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 inspection, repair 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.
