RRC ABS and Trac warning lights...

Dear all,

I am currently being plagued with an errant pair of warning lights on my 1994 RRC 3.9

Try as we might, we can't seem to get to a point where the lights are consistently extinguished. The fault has been traced to an air gap in the front passenger side of the vehicle. My LR mechanic has reset the senor and has now replaced the stainless steel cage that the sensor sits in and all was well until I reversed it out of the workshop, when the lights came back on again.

I reset the warning lights using the '3 times switching on and off' method and that cleared them, but the next time I started the car they came back on again. There doesn't seem to be any rhyme or reason here - sometimes the lights go off once the car has started, as they should, but on other occasions they stay on.

It's going back in again next week where we will swap over the sensors to see if the fault is with the actual sensor itself, or is due to something else that's as yet undiagnosed.

Next steps will be to source some replacement sensors, but I'm aware that the original WABCO sensors are no longer made, so I'll have to go Britpart instead...

Any thoughts on what else we can try? All answers would be very much appreciated.

Best regards

Marsh

Could be a wheel bearing worn allowing the sensor to be pushed back.

Thanks for coming back so quickly - well reminded; the wheel bearings were in fact replaced today, as that was a possible culprit.
