hey,
wonder if anyone can help me.. have a slight issue! i put some alloys on my car, but the back ones were rubbing like hell, i drove around abit (quite slowly) and there was a slight knocking??
so anyway, got some spacers and everything was looking ok but after i got all the wheels on and had a quick drive the ABS light was on and stays on... it says in the book because its found a fault it has disabled the abs?!
ive checked the fuses, cables and wires and nothing seems obvious

anyone got any ideas??
cheers

Sh!t happens [8)]
The slightest fiddling in wheel arches may cause an ABS wheel sensor to disrupt in it's cabling. They are very sensible stuff.
Try find any sensor cable connectors as near sensor as possible - then disjoint connectors and do an ohm's measurement out the sensor.
You must have a reading in vicinity of 1K ohms on good sensors & cables.
The ABS ECU checks for sensor continuity each time ignition is turned on - if a fault detected - then the ABS lamp comes on and stays on.
In rare (!) cases it may be the cabling/connector on the ABS valveblock itself.
