Intermittent Traction Control Light and ABS Light

Interesting. I don't think I found this but it does sound feasible. Not sure if I changed the hazard switch or not tbh but its worth a try.

Thanks for all your input Steamship and MJ. Looks like a job for the weekend owing to lack of time and dicey weather. I think it is within my limited capability.

MJ can I substitute WD40 for contact cleaner?

Is it prudent to get hold of a new hazard flash unit if such an item is available?

Only had one small 'thump' in the gearbox happen last week when the traction control / abs went nuts whilst getting battered with snow up in Newcastle. Since then has been shifting smoothly. Will run another scan after the weekend's fiddling.

All those engine components are run from the same fuse - S117 'control element fuse' which is a yellow 20A in the ECU box. I'd suggest replacing the fuse and giving the fuse holder terminals a spray with contact cleaner / WD40. Its likely there is some corrosion or grot on the terminals from when it was damp in there.

I have a box of hazard switches if you want one posting, or are passing to pick one up

Checked in the ECU box and all fuses were in a state of corrosion. The 20A fell apart after tugging it out! Liberal amounts of contact cleaner and all fuses replaced.

I noticed some condensation to the underside of the ECU box lid. You would think there must be some way of ventilating this box to alleviate this?

Crash implausible error has disappeared.
All intermittent have gone.

On to the Airbag issue.
