hello mate
you think you've strange ABS, the abs light on my car is constantly on when you start the car abs not working at all. but when you drive on to a four post ramp and switch engine off and restart it the abs goes through its self test routine and the lamp goes out, as soon as you reverse the car off the ramp the lamp comes on again. every thing has been tested many times both the relays have been changed, all the sensors seem to be in good working, fluid level is where it should be all connection are clean, has anybody else got any ideas please
regards nick.
