Hi. New to the forum
I have a Land Rover Defender 110 2005 with a Wabco ABS system on it.
The vehicle had been standing for a few months and the battery was flat. The customer jumped started the vehicle and had Handbrake warning light, ABS and Traction control lights on dash.
4 fault codes stored for Input/Output valves short circuit to ground.
We did continuity checks on the wiring and all is ok. We have changed the main Abs unit by the inner wing, fault still present.
We changed the ECU under the drivers seat. Coded in the new unit all ok. Chassis number is in the new unit. The traction control light is now off. The Abs light comes on with ignition, goes out but comes back on 2 seconds later. The handbrake/Fluid level red light is on permanently. We have checked the wiring, and found no fault. Tried another fluid reservoir to eliminate the fluid switch. Still on. No fault codes stored.
The Ecu must have had a fault as the codes have gone and traction light operating ok. I feel the hand brake light is the issue.
Can anyone supply and accurate wiring diagram or shed any light on my problem. Thanks
