Peugeot 206cc airbag light on

[markallanwainwright]

Update Col.....BBA can only reset unit if airbag has been deployed. Spoke to a clued up guy from DSMC salvage, it was him that supplied my replacement unit. He thinks as two units have blown he suspects there is a live fault on car which needs to be traced before fitting another unit. Any clues as to what things I should be looking at and does anyone know of a good mobile auto electrician in Romford, Essex area?

You really need a code reader now. It could be anything from a crash sensor, to a seatbelt stalk. If you can come back with fault codes we can assist.
BBA should be able to tell you if there was stored crash data in the unit

The guy that diagnosed the fault tells me "111 disarming of the passenger airbag switch 64 van network".

[Capncol]

The fault is in that circuit in that case. Check the keyswitch and the wiring between it and the airbag ECU.

Thanks Col, auto electrian will check it out on Tue, will let you know how it goes.

Just had another mobile elec looking into problem. He's pretty sure it's not the airbag unit. Suggested I change the passenger airbag switch. If it still has issues after that he says it's a big job to trace the fault...."Something is not communicating with some thing else"? The wiring from switch to unit is good.

Just changed the pass airbag switch but still having all the same issues. Tech says he'll have to check all wiring, could be a half hour job or a ten hour job, depends on how lucky he is finding the fault. I think I'd be happy forking out £150 to get it sorted, but obviously he can't quote that price. Other than that I'll have to sell as seen for a cheap price. I can't believe a car that's only done 23k miles could be such a problem.

A) it's a Peugeot

B) it's old enough to have been messed around with .. a lot of people refuse to pay out to have the jobs done properly so it gets bodged and sold on ..

As I said above, check the switch AND wiring. You've changed the switch, you now need to trace wires to airbag ECU and check them out.

[markallanwainwright]

Yes Col, wiring was checked between switch and unit, no fault Found.

[markallanwainwright]

Still have the same problems but today I learned that at some point the car may have been started by using jumper cables, would this have buggered it up?

Been a while since I posted about airbag issue. In the end my diagnostics guy bought the car, and fault from me for a couple of hundred quid as he couldn't give a price on how much he would charge to fix it, "depends how long it takes to trace fault". Anyway, he recons he found the problem after 8hrs of work (would be £65 per hour), it was something to do with a unit in the indicator stalk. He now ends up with a fully functional mint condition car and I end up with the £250 I spent out on it. Thought I'd share that with you as "indicator stalk" never showed up as fault on diagnostic test.

Thanks for the update. That is the comm2000 unit you are talking about
