Hi
Ive got a Vauxhall Carlton 2.0 CDX. 1990
It had a broken ABS sensor which I have changed.
The ABS light still doesn't go out after the self test time.
I have checked the resistance of all the sensors and they are all around
1000 ohms. This reading is obtained at the ABS control unit as well.The car has also had a new brake pipe fitted culd this have caused a problem.
Do any of you have any thoughts as to what may be causing this?
Thanks
Phil
Thanks gary
Unfortunately the ABS light stays on before the car has moved.
It seems the error is with the control system somewhere.

You'll love this, a mate's Honda Accord Coupe 2.0 (Import) recently had the ABS warning light come on, he paid £300 for a new ABS unit, this did not cure the problem.
It seems that these cars disarm the ABS system if a rear brake light bulb has blown!

I'll check before I do anything else!
Phil
I should add
The ABS unit was unplugged as a precaution when some welding was carried out recently. Could this have caused a problem?
Phil
Well, if it wasn't plugged back in....
:-)
Try making sure it's all plugged back in correctly.
Pete.
Unit plugged back in correctly and brake lights both working!

It was the relay that supplies +12v to the ABS unit that was not working.
