Hello everyone,
I’ve a 3.2 Vauxhall omega 2004 and have an air bag light on and when I stick the computer in it reads “87v A/C cuttoff relay voltage low”
Think I’m Gona check fuses etc but does anyone know the problem straight off ?
Anyone have this problem before any ideas any help would be appreciated

It could be as simple as a loose/damaged plug under a seat, or that the steering wheel airbag was unplugged with the battery connnected.

There are side impact sensors in the doors as well, so these may have gotten wet or the door looms have cracked at the hinges.

Ideally it needs plugging into a better code reader, ideally a Tech 2, to precisely identify which component it thinks is faulty

It was a damaged wire under the passenger seat thought might of been a relay thanks for the help much appreciated!

That's usually the cause, but the Omega doesn't seem to suffer from that as much as some cars

Other cause in late Elite's is the passenger seat occupancy detector.
