Citroen Relay / Jumper air bah / horn failure

Post by Gary_Lead01 »

HI I am sorry if this has been posted before I have had a search and can't seem to find it

anyway
my Relay 2.2 35 XLWB minibus now being converted to a camper has an airbag and horn failure
when searching for this I found most issues are the squib or comms unit behind the steering wheel.

these are extremely difficult to find new so purchased a used but warrantied one
after replacing it, easier than I thought! I still have the issue

has anybody had the experience or help with further diagnostics.

I would have put money on this being a comms unit failure.
What codes are you getting on the airbag system? Have you checked if there is power going to the horn?
