maxellfullmoon Posted November 26, 2007 Share Posted November 26, 2007 The ABS and downhill lights has started to come on my 2000 Discovery. Sometimes they will be off when I start out in the morning then come on later down the road. Can someone give me a clue as to where I should start looking for the problem?

BogMonster Posted November 26, 2007 Share Posted November 26, 2007 ABS sensor fault is the most likely. You need a computer to read the fault codes and figure out which one, anything else is working completely blind. Quote Link to comment Share on other sites More sharing options...
Tobias Posted November 26, 2007 Share Posted November 26, 2007 I have the same problem. Any suggestion on which computer/code reader to use and also to reset the faults to make the light go out? Tobias Quote Link to comment Share on other sites More sharing options...
BogMonster Posted November 26, 2007 Share Posted November 26, 2007 Any of the proper diagnostic systems will do it I believe i.e. Testbook/T4/WDS (dealer systems), Autologic/Rovacom. Not sure if you can reset the codes with one of the generic code readers or not. Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted November 26, 2007 Share Posted November 26, 2007 Is there any way of getting the ABS to display it's codes without a diagnostic computer, as you can with the older systems? Quote Link to comment Share on other sites More sharing options...
BogMonster Posted November 26, 2007 Share Posted November 26, 2007 Not that I am aware of, but there might be and if there is I would be interested to know about it Quote Link to comment Share on other sites More sharing options...
cosworth Posted November 26, 2007 Share Posted November 26, 2007 9/10 we end up fitting a complete hub rather than just the sensor. they are an absolute pain in the tits to remove without breaking!! be prepared for easy £200 + for a hub if bought from a dealer. compare that to £14 for a new range rover abs sensor Quote Link to comment Share on other sites More sharing options...
maxellfullmoon Posted November 26, 2007 Author Share Posted November 26, 2007 Looks like I need to get a scanner. Do you know what OBD-II protocol Land Rover uses? Quote Link to comment Share on other sites More sharing options...
russ1 Posted November 29, 2007 Share Posted November 29, 2007 Fault code it will bring up is probs p1590 mine has had the problem for a while now but dont really want to pay £200+ for a hub ( i need two ) I used a snap-on fault diagnostic system i it wouldnt read the ecus under landrover setting so had to use the eobd setting and it wont clear the lights. Took it to a local dealer with testbook and came up that i need two new front hubs and shuttle valve was sticking. They cleared the faults and with in a mile of driving they were back. Dont you just love landrover and there daft hub ideas! Quote Link to comment Share on other sites More sharing options...
Tobias Posted November 30, 2007 Share Posted November 30, 2007 Cosworth: what is the problem with changing the sensor? Does broken bits of the sensor fall into the hub? I have the fault and a new sensor lying in its bag. Should I not even go for it unless I have a new hub? have ordered Nanocom to read and clear codes, will receive it within a few days, I hope.

Ally V8 Posted November 30, 2007 Share Posted November 30, 2007 When you fit new sensors to DII hubs,take off the little o ring and bin it.Instead use a small smear of silicone to seal it - the o ring is a tight fit and slightly bends the bracket,which keeps the sensor away from the reluctor ring.This is why so many people just fit hubs,as long as the bearing and reluctor ring are OK there is no need.

Tobias they are usually seized solid mate. by all means give it a go but be careful. you`ll also more than likely need some heat to remove the shaft from the hub. good luck.

JimAttrill Posted December 2, 2007 Share Posted December 2, 2007 Why change the hub when all you need is a sensor? Why change the sensor when you can remove the o-ring and belt it to clear the fault? You guys must be made of money Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted December 2, 2007 Share Posted December 2, 2007 Jim,belting a DII ABS sensor is not too clever - they ae not like the old RRC/D1 sensors. Plus if you look for a decent supplier they are not megabucks anyway. Quote Link to comment Share on other sites More sharing options...
gkm24 Posted December 3, 2007 Share Posted December 3, 2007 When dealing with ABS systems in the past I have never needed more than an AVO meter. In the first instance I always jack up each wheel in turn and check the output of the sensor using the smallest voltage setting on the selector. In all cases, which ever sensor does not give a reading will be the trouble and replacement of that sensor has cured the problem for me. Sometimes when the new sensor is fitted the warning light does not go out straight away (if at all it is on when you start off) as the ecu needs to get a wheel speed agree/disagree message from the sensor. Apart from this, as long as the ECU is getting at least 13.2 volts I have always managed to fix them this way. I must admit that I am not a Land Rover technician ( BMW and Mercedes tech) but despite having all the technical tools, this way has always worked and been faster than the hi tech approach. Hope that this method can be applied and will work for you, although as your problem is intermittent, you will have to have the fault present before it will be able to be detected this way as it sounds that the sensor is failing rather than completely failed.
