Land Rover Mechanic Chicagoland Area - ABS Issues D1

[discostew]

Let me correct myself.
My experience was with a D2-

Sharing a challenging experience myself understanding why my abs light was constantly illuminating - yet inconsistently. I’m not referring to a steering knuckle- (cv joint). Turned out - in my case -was the wheel bearing slowly chafing as it was dry and failing. Therefore collecting dust on abs senser - which is essentially a magnet monitoring the wheel bearing frequency.

A D1 and D2 ABS systems are so different its really not worth comparing them. If the wheel bearing gets loose on a D1 the axle can wobble a little in the front and push the sensor away from the reluctor wheel.

It really depends on what the code is. When the bearings get loose the truck has an unwanted ABS activation that makes the truck feel like its going to glide right thru the stop no matter how hard you push on the brake pedal. If it's a circuit fault then you need to verify the sensor measures about 1K ohms. If it does you need to go all the way back to the Wabco unit and measure the circuit from there.
