ABS light

[Merlin]

On a 90 RRC 3.9efiA is there any way I can put the ABS light out.  All the brakes work fine but the light comes & goes as it pleases so is there a fuse or anything that will put it out permanantly.

[Range Rover Blues]

No.  If it's coming on then there is a fault somewhere, maybe one that's clearing again I don't know.

If it doesn't come on at startup then it's an MOT fail.

Pm me if you need any help with it.

I have a car I'm doing up to sell, some claud had connected the dash warning lamp to the ignition lamp so as to fool the MOT tester, never mind that the brakes didn't work :shock:

my abs and traction control light comes on when i go over 60mph but once its turned off and restarted it goes.
Its bugging the hell out of me

Serviced the front brakes this weekend, hubs off, inner bearings serviced as well but the light still comes on intermittently.
When it warms upn a bit (work outside & bl--dy cold up here now) I will fit new discs to the rear but have been told the ABS rings are hard to get off.  MOT a week Tues. so still time to solve the problem.
It only started to come on after some seriously muddy off-roading so am hoping sh-t is the problem.
Any tips on getting the rings off in one piece?, I don't have heat.

Check that you have no crap bridging the ABS counter rings on ALL 4,I had a Honda accord once that had an intermitent ABS problem,turned out to be some cassette tape had wrapped around the sensor ring and the sensor its self couldnt count the gaps or if they are the magnetic sensor type make sure it isn't choked with iron fillings

Perform a blink test, the ECU will have logged the fault even if it clears during the next diagnostic cylcle ie when you turn the ignition off then on again.

It's proably a bearing coming loose, it happens when you put big tyres on

cheers,i'll give it a go.I've done the play on the back,need to check the fronts.
One thing i have noticed is vibration at speed,i wonder if some balencing weights have come away from the wheels with the off roading.
I'll do the blink test to see whats in there.

[Range Rover Blues]

Or mud in your tyres.

That vibrating could be the casue of the ABS light too.

hmm,never thought of that as there always clogged up with mud  
I'll look at it when it gets a bit warmer outside.

thanks for the help  8)

My traction control and abs lights stay on too since I tried to change the rear hub(just to find it didn't fit properly).
For some reason the outer bearing of the "new" hub is further towards the wheel so could only get one bearing lock nut on instead of the two.
So had to strip it all down again putting my disc/abs ring etc on my old hub just to find now my lights won't go out..

Any ideas  :?:  :?:

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:

YOu really need to get a Haynes manual

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

Oh, replace the blue relay :)

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

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:

ok thanks for that will give it ago when i've sorted all the other problems(like air suspension,rear prop,rear hub,handbrake,i will stop there).

Not tried it TBH, but that surprises me :?
