Airbag light Berlingo 2010

Post by Washeymag »

I have a 1.6 Hdi XTR 2010 model and the airbag light came on and a message says Airbag seatbelt tensions faulty as I went to put the car in my garage tonight anybody got any ideas what the problem could be thanks in advance.
Had CODES read and they said the problem was N/S rear passenger area was a permanent fault code garage said check all connections and then have it re read again any ideas what in this area for connections for the airbag or seat belt tensions.

Very often connections under the front seats. As the seats are moved the wires move and after a few years find worked loose or break .

Had another look at car today does anybody know do the 2010 Citroen berlingo Multispace XTR have seat belt tensioners on the rear seat belts as I can't find any wiring  as code reader is pointing to N/S/R seat belt
Does a permanent code need to be cleared by code reader or does it clear it self.

Thanks in advance

From the available data I have there are no rear seat belt pre-tensioners on this vehicle. If the chap diagnosing it is using a generic code reader, then it could be interpreting the data incorrectly. According to the data for this model there isn't even a rear passenger warning system.

Thanks Marc that what I was thinking at the time I booked in the next couple of days for the CODES to be read again I have cleaned and checked all the connection under the the two front seats and on the two front seat belts will report when this has happened.

Fingers crossed it's sorted it out.

Do you know what the location is of the airbag ecu?

Thanks in advance

The unit is located inside the central console. Caution though - always disconnect the negative battery terminal and don't allow it to reconnect. Wait 5 minutes or 10 minutes if there is an airbag anomaly before undertaking any work on the airbag control module or systems and never remove the airbag ECU module with the connectors still connected (risk of triggering).

The car is now sorted took car back to Citroen and Peugeot specialist and had CODES re read same fault which proved to be a ghost fault the only people to sort this is a Citroen dealer.
So the specialist booked the car into dealers who refreshed the software on the Airbag ECU and also found corrosion on one of the connectors and had to replace the connector.

The total bill was £80 from the specialist which I thought was reasonable.

Thanks Marc
