Peugeot Traveller I airbag control unit repair

What is an Peugeot Traveller I airbag control unit?

The Peugeot Traveller 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 which airbags and seatbelt pretensioners to deploy, and monitors the system continuously.

The control unit is installed in the Peugeot Traveller I (since 2016). It checks itself. If there is a fault, it reports the error via the airbag warning light.

The sensors in the vehicle continuously send their measured values to the control unit. It evaluates these signals, detects a collision and, in an emergency, enables the firing of the appropriate restraint devices. It also constantly checks the connections to the airbags and seatbelt pretensioners while doing so.

After an accident it stores crash data and locks itself.

Why is the Peugeot Traveller I airbag control unit defective?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Other causes are aged electronic components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.

Crash data cannot be cleared with an ordinary diagnostic tool. The control unit stays locked even if the airbags themselves are undamaged. A repair by a specialist workshop is then the usual route.

Voltage spikes arise, for example, from a weak battery or from jump-starting. Electronic components age, solder joints become brittle, and moisture attacks contacts. Typical signs are a permanently lit airbag warning light, a fault memory that cannot be cleared, and a diagnostic tool that cannot connect.

Common error codes for Peugeot Traveller I airbag control unit repair

The error codes for the Peugeot Traveller I airbag control unit point to communication faults, internal control unit faults, problems in the firing circuits or stored crash data. The respective code shows which type of fault is present.

The following list shows codes that often appear in the fault memory of the Peugeot Traveller I. Depending on equipment and software version, a unit may report further codes that are not listed here.

• 7362 → Airbag system fault, to be clarified by diagnosis
• B0091 → Restraint system fault
• B1000 → General restraint system fault
• B1015 → Airbag system fault
• B1139 → Restraint system fault, exact cause unclear
• B1193 → Airbag system fault
• B1206 → Restraint system fault
• B1342 → Internal airbag control unit fault
• B1649 → Airbag system fault, to be clarified by diagnosis
• C69F → Restraint system fault

Error codes are read out with a diagnostic tool. A code alone does not prove that the control unit is defective. Connectors, wiring or an airbag module can also be the cause. Only an inspection will clarify it. Therefore write down all the codes that were read out and enclose the printout with the unit.

What part numbers are available for the Peugeot Traveller I airbag control unit repair?

The part number is on the label of the control unit. It determines the exact version, because within a model series there are different numbers depending on equipment and year of manufacture.

Here you will find known part numbers of the Peugeot Traveller I. The list is not complete.

• 1479489080
• 1481002080
• 1681055580
• 98 039 168 80
• 9817062880

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

The route to repair: have the fault memory read out. Disconnect the battery and remove the control unit. Create a repair order online and send in the unit. Inspecting, repairing and testing usually take 3–4 working days at Airbag24.

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.
