Technical 08 driver squib circuit 151

[jonik]

Airbag light popped up while driving, here's a pic:

Can't clear it, everything looks okay. Anyone had similar problems? Same (and only) error even without squib or airbag connected.

open circuit means open
it therefore is logical that an open circuit airbag warning would mean a break in the wire somewhere?
does your horn work as i always found no horn when the clock spring wiring had broked
isnt mes brilliant
ps crp129 by launch is quicker faster and more direct mind

As S&B says the most likey fault is the clockspring. A quick check if you have the airbag unplugged is to short out the plug that connects to the airbag with a short piece of wire. If the fault changes to driver airbag short you know the wiring is OK.

Horn isn't working but I'm not sure it was working before
Tried to short out the airbag wires, no change. So it should be the clockspring?

Checked wires between airbag ecu and clockspring. Blue wire is ok but I'm not sure about brown/white, it has continuity to blue wire. Should it be like that?

If horn is U/S too then it's almost certainly the clockspring at fault.

Since its a Rotating Contact setup

Try rotating the steering wheel to different angles - Suddely does the horn work?
if the horn is working and then you move steering wheel away and it stops

Again it points to C/Spring been duff

Clock spring does not have a rotating contact.

While rotating the wheel might re-close a break on the flat conductor, it's unlikely.

It was the clockspring, old one was spinning freely. Thanks for the help
