ABS light

Range Rover Blues:
It's easy to disturn the ABS sensor when you refit the hub, especially if it was the wrong hub.  Do a blink test, this will tell you which corner is at fault.

How do I do a blink test :?:  :oops:  :?:  :oops:  :?:  :oops:

Range Rover Blues:
YOu really need to get a Haynes manual :wink:

Pull out the blue relay from under the passenger's seat.  There are 3 on the outside edge behind the trim but if you move the seat up and forewards you can just reach it, it's a 5 pin blue relay in a blue plug.

Under teh front of the seat there is a small sqaure plug, 2 of the wires to it are balck and black with purple stripe UURC, they are diagonally opposite.

Turn on the ignition and then fit a short jumper cable to these 2 wires, leave it connected.  On the dashboard the ABS light will blink out the fault code.

It will go long blink, short blink (single), 2, 3 or 4 blinks (first part fo code), then up to 14 blinks IIRC (second part of code).

It will keep repeating the code untill you remove the jump wire, it will then complete the sequence and come back to diagnostic mode.

Re-insert the jump wire and you will get the next most recent fault, keep going then untill all faults are cleared, this will be indicated by a 7 second pause after the long and short blinks.

Tell me what codes you get and I will look them up :wink:

Oh, replace the blue relay :)

enak:
First part of the fault code goes up to 6  and second part up to 15 :wink:

List of fault codes here

Also to note, if you remove the jumper wire and wait for the fault code to finish reading and the light to return to steady then turn the ignition off, it will clear the fault.  If you turn the ignition off with the jumper wire still in it won't clear the fault.

You can then repeat the process to read all the other stored faults and clear them too.

Once you have cleared all the faults and with the jumper wire removed, the ABS light will blink briefly at start up to indicate that their are recently cleared faults and that the vehicle should be road tested.

On the road test, if the light stays on, you still have a fault.  Re-read the fault codes and you can narrow down the problem...

e.g. 2-15 can usually be solved by pressing the sensor in further.

Mine has a fault where the sensor wiring has rubbed against the wheel and worn out the insulation down to the wires... this meant the wire corroded and even repairing the wiring (not recommended) doesn't resolve the fault because the wiring is so badly corroded.

Oh, and to add, I don't need to remove the relay on mine to read off fault codes... :shock:
