if it won't connect to the abs using a scan tool, i'd be checking all the fuses, also there is a reverse polarity protection relay under the steering wheel for abs, try swapping this out with another one (needs to be a reverse protection relay - try wreckers).
if this is all good, i'd be check for power, ignition and earth at the module, and/or just replace the module, which is behind the drivers side kick panel.
the unit under the bonnet won't cause a no comms problem.
arhhhhh
any pics of module in kick panel and or relay under steering wheel, abs unit in engine bay has power to everything

nope. but relay is not with other relays under there, it is on a brakcet that is attached the metal beam that the cover hinges off.
you won't be able to miss the module if you pull the kick panel. it's in the same spot the ECU is, but other side of car.
you legend, on the metal bit with hinges mine has 3 relays there and one loose green plug? i bought the car like this so i dont no what its for?
abs
ok found the module just need to find that relay! do you know the colour of the wires??
Where is this relay lol? I have changed the unit in kick panel and still no difference?Originally Posted by wamboin23
That green plug may be the ABS diagnostic plug. See how you go with (checking?) the brake switch but I'll have a look (when I can) at accessing the ABS codes via that plug.
Nope. BCM diagnostic connector.
