MINI Cooper and Cooper S - Airbag Fault - Simon Collett

Hi

I have a 2002 mini cooper. My issue is that the airbag light is on. code reader is giving error 10/05 - Firing circuit side airbag front left side.

I have read posts explaining this is a bad connection under the seat.

However my issue seems to be strange, if I clear the error and disconnect the yellow plug under the passenger seat the fault stays cleared. However if you plug the yellow connector back in and turn ignition on the fault is shown again.

Can anyone explain this?
Why would the airbag fault only show when airbag is connected? I have tried a new airbag but this also errors.

If airbag is not connect ted the error can be cleared and stays cleared.

Any advise would be greatly received.

Thank

Simon

With a fault in the system , or the yellow plug disconnected, an error code should be logged. With the plug not connected, there is a gold short circuit bar that connects both pins together that should flag a fault back to the airbag ecu. From your description, there could be a fault in the wiring , or somebody has interfered with the wiring to falsify system function. The only real way to check it , is to verify continuity of the wiring from the airbag module to the seat . Access to the module , located under the handbrake, is not easy . The seats and carpet , trims will need to lifted. Mini do a modified wiring loom for the under seat connectors because they were continuously troublesome.
