Hi Gents,

I just become a new proud owner of a Disco 2 TD5.
Before that I had a Freelander 2.0DI and i'm familiar with some issues.

When I bought it the 3 Amigos were on my dash. Went to the mechanist, connect to OBD, info showed on the rear right ABS sensor. The Mech. Erase the error and the lights went off. Now when my rear wheel is running in air the lights come up again, then I turn off the engine, press the unlock button on the key, turn back the engine and the lights are off again.

It's quite strange also when the alarm is triggered. When I unlock the door, the dash light for the alarm is splashing fast. When I try to deactivate with the button on the remote I don't succeed. I turn the key to second position and the Amigos are there again with no reason. Turn off the key, close door, super lock, unlock again, turn key back on....the Amigos are OFF.

What could that be. Is the sensor causing all the confusion, is there some fault in the ECU??

All the help is welcomed.

Thanks to all,
Zoran

Got to be a clue there.
The usual faults which can cause the 3 amigos (ABS, TC, HDC) are either an electrical problem with the shuttle valve switches or a faulty ABS sensor on a wheel hub. There are some other causes too.
In this case it looks like it could just be the rear right ABS sensor. The usual fix is to replace the hub, complete.
Clearing the fault from the SLABS ecu is not going to repair the fault.
The BCU (body control unit) has nothing to do with the ABS, so there's no need to be going there.
 
Hi my Friend,

I agree with your opinion.
If I only change the Sensor, would that be ok?
My local dealer will supply me with a new on from Bearmarch.
I'm also wondering how the locking and unlocking the doors helps the amigos to disappear.

Like I mentioned...if the lights appear while driving, stop, turn off engine, lock doors, unlock, turn key back on, amigos are OFF

I need your opinion on this.

I was thinking more of the interaction between the lights and the locking, but I did say I was guessing! Where does the ABS box live?

Hi, IMO all those lock/unlock/amigos things are coincidental, so is the sensor fault code which might be hystorical...as long as all the 3 amigos are off together and the ABS warning doesnt stay on alone untill the speed exceeds 10mph it's not a sensor related fault... forget about locking and unlocking insist with the ignition on/off and the same will happen...there could be few reasons for that even if SVS or sensor/hub faults are most common... if some generic code readr wasw used get it plugged in a dedicated tool and you can check the sensor outputs live
 
Hi all,

Just quick update on the problem I had.
I've replaced the ABS sensor with brand new one. Again the problem exists.
I start up the engine, drive for a while...and there it is...ting ting ting...three amigos are ON.
Park the car, turn off engine, turn on engine and the light are off.
It looks like the off/on engine is resetting the error code or something, but im not sure why it appears while after some driving.

Is there maybe some historical error in the abs computer, maybe some water leak in it, low level of break fluid...
I'm so confused...

I love my disco, and I have when this is happening to him.

Please help how to sort this out.

Zoran
 
the answers are already there in my post above your's... read it again, i told you it's not a sensor issue and explained why, according to the symptom it's most likely SVS issue...if you dont have access to a dedicated tester do the SVS mod "in blind" cos it doesnt hurt anyway

Hi Friend,

I read your previous post... but I couldn't quote understand it. Sorry
I just like to mention that When I start the engine...I can hear the ABS module doing the test (ggrrrrr) and even with the 3 amigos on...my TC still works fine.

About that test of the SVS....can you please explain it to me...how to do it in blind...because I don't have tester or some other equipment.

Thanks

Gents,
I know this is and old post, but I didn't want to open a new thread for and issue that is already existing.
As I mentioned before, 3amigos are still on.
  • Went to one Land Rover service, on reader shows rear ABS Sensor (sort it out, put brand new one) - Problem still exist
  • Went to another Lad Rover service, on reader shows ABS shutter valve. (not sorted yet)
When is the problem happening:
  1. When that wheel slips, it turns ON the amigos.(sensor is brand new one)
  2. Also the 3 amigos can go ON sometimes during normal breaking (wheel not spinning).
So...is it the Shutter valve the main issue or the sensor (what is being changed). Is it possible to trigger the 3 amigos when only that sensor sense a slip ? How come the rest sensors works fine? How come sometimes on normal breaking the 3 amigos turn on ? So confused...just wondering can the SV cause all those faults?!

What do you recommend to do next, change the shutter valve or examine for something else?!
(remember form above about different fault codes).

Thanks
Zoki
 
You have two problems:
1. the sensor issue which was not cured by new sensor cos the fault code was most probably caused by play in the reluctor ring which means you should have replaced the whole hub not only the sensor,
2. the SVS(shuttle valve switch) thing which may not be cured by new SVS pack cos the problem is within the modulator and you have to do the wiring mod to be OK, in most cases the wiring mod is enough you dont even need the switch pack.

first of all fix the SVS cos that causes more intermittent amigos than a hub issue, also if the 3 amigos are resetting all on ignition and no ABS warning alone untill the vehicle exceeds 10mph the faukt code is not sensor related.
 
Wow,

Thanks for this my friend.
I've never thought that two different problems occur same time and cause me misunderstanding.
I thought that the SVS is the guru for all the problems and that's what I've learned from other LR owners.

So, lets tide up the belt and lets go to work.
I will listen your advice and I will change the SVS firs...just to see what will happen next.
If this is sorting the issue, fine...if not, the HUB is the next one.

Thanks for the respond...I can say the real LR gurus are here on this forum :)

Best regards
Zoki
