intermittant abs warning light
as title says, abs light on dash comes on and off randomly
get in car, its not on, few miles down the road notice its illuminated, get to destination may have gone off or the next time i go to drive the car it will have switched off, has been off for last few days...
when illuminated my abs is def not working (checked this by dropping anchors at 40mph)
have read threads on here about abs faults, couldnt find a thread that described my symptoms exactly, but have checked three fuses on top of battery, all looked ok but will replace anyway
other than being a faulty abs pump (which i hope it aint) i read it could be a wheel speed sensor?
i know it needs plugging in to get codes but currently dont have access to vcds or similar, so am just seeing if anyone would have any other suggestions for the mean time?
anyone know if the abs system is earthed via the rear diff, as i think my earth strap is shagged and this could be the cause of the problems?
any input appreciated
