Another Airbag question...
Airbag message on dash. Comes on after starting car, and then turns off.
Checked both yellow and blue connectors under both seats. Used contact cleaner, and switched them on and off several times. Still the message on when starting. Also found a connector not switched anywhere under driver's seat (LHD). Seat has memory adjust, so guess that switch is there for no memory layout, as couldn't find where to connect it. What should I try next? Thanks in advance for any help and apologies for my English . Regards. |

If it stays on, then you would need to investigate. The plug is a seat belt reminder switch. Not all markets had or required it. It can be left not used.

Pictures are for:
1. Key in position 1 2. Key in position 2 (engine not running) 3. Just after engine starts. Message will be on for 2 seconds and then turns off. (message translates as "airbag failure" from Spanish) |

The speedometer set needs to be opened to check on this. The fault may be the plugs under the seat, it could be worth replacing the plugs with different types. Members here have used THESE to good effect. It may also be the crash sensors under the carpet. You will need access to a T4 diagnostic system to confirm without replacing parts. Are your plenums clear and carpets dry? Even though you live in Canary Islands, you will still have a little rain. If the plenums are blocked, and the water gets below the carpet, it may be little water, so you may never get to notice it, but it could still be enough to do the damage to the sensors over time. HERE are some links for various information on the sensors. HERE is information on checking and clearing the plenums.

Thanks a lot for your answer.
Owned the car for the last two months. Checked plenums, and it's dry at the moment, but don't know if there's been water in the past, as it was blocked. Have no access to T4 diagnosis, so it's time to study those threads. Thanks again. Regards |

The seat belt warning circuit also includes the 'clock spring' mechanism behind the steering wheel. If the under-seat connectors prove to be definitely OK, I'd suggest exploring the 'clock spring'. The deactivated warning light suggests the fix is not that easy to do.

I use a wire from a net curtain to drop into the plenum tubes around 1-2 metres. The above issues do not solve your current problem, of course. And they may not be a cause, but these issues are common, and are worth watching for, to prevent future issues.

Thanks both of you.
No sunroof, so one less problem to worry about. Polen filter was changed before purchase, so don't know its previous condition. I will change blue and yellow connectors as a first step and see what happens. If that fails, I'll probably come back for further advice. Regards |

As you have no access to a T4, have you thought about getting Toaf?
http://toaf.roverki.eu/index.php/en/ almost like a T4, or perhaps a poor man's T4 but invaluable to us who don't live in the UK. It can help a lot with diagnostics especially things like ABS & SRS. Our cars in Sweden don't have any seatbelt warnings either. Regards |
