Hey guys,
I have 2000 Defender 90 TD5. It's the XS model so came with ABS.
Over the last year it had developed the infamous 3 amigos. But they didn't all light at once.
When you started up ABS and TC remained lit. Then upon using the brakes for the first time after starting, there was little to no braking power. It felt like the brakes were grinding. After letting off the brake and braking again they worked perfectly (without ABS) but the brake warning lamp came on and stayed on.
I had the codes read with a Hawkeye Pro and it was throwing everything related to ABS. The mechanic suggested removing ABS entirely and replacing with non-ABS braking system. He specialises in Land Rovers had done it previously to another Defender.
So now the jobs all done, braking is perfect, but the 3 lights are constantly illuminated.
Reading the codes shows the following:
"ECU ground or Reference ground fault"
"Front Left sensor electrical failure"
Clearing the codes gets rids of the sensor fault but ECU ground fault stays, and the 3 amigos never go out.
Has anyone has any similar experiences or idea on where to start looking? I used a multi-meter to test the ground from ECU to -ve terminal and it was fine.
