Apologies if this is posted in the wrong place. Having finally sorted my DPF woes I now have some courage to tackle airbag lights. I have the general airbag light and also the passenger airbag deactivation. I have read fault codes using a LAUNCH OBD scanner but to be fair I sent think its that comprehensive a tool for this car. It gives me the message fault on data wires, which based on the fact I have tested the switch to be good would seem to be a likely problem. The airbag ECU under the carpet looks mint no water ingress. So I am starting to consider how I can test the wiring to see if there is a fault.
I have read on the forum problems with corrosion on the fuse box (bsi) and the under bonnet fuse box does have a clip brocken however the drains are all clear under the windscreen and the fuses look OK.
I had in mind to test the continuity between the fuse and possibly the wiring to the airbag ECU and so my question is. Has anyone does this and could you advise the procedures for doing this without damaging the car or airbag system. Also does anyone know of a wiring diagram, there isn't a Haynes manual available for this car.
Appreciate any help to sort this problem
