Tibout Posted February 18, 2011 Share Posted February 18, 2011 hi i'm having some trouble with the abs system. it's a disco 1 300tdi. so sometimes when i'm driving the abs light comes on but its kind of a very fade lights and turn off after a few seconds. also sometimes the abs over-react specially if im turning at very low speed (like getting in the drive way) i read some articles that if the abs is not working properly it could disable the whole braking system! and also there's a code reading method thingy that we can do to know which one is the faulty ones. anyone know about this? or could it be a loose sensor or dirty one. thanks thierry Quote Link to comment Share on other sites More sharing options...
davek0974 Posted February 18, 2011 Share Posted February 18, 2011 Don't worry, it won't disable the brakes, just the abs stops working when there is a fault. Google "discovery abs codes" I think that will get you started on fault finding, all you need is a paperclip, pen and paper! It's easy.

DDO173 Posted February 18, 2011 Share Posted February 18, 2011 I have some similar symptoms of what your experiencing. http://forums.lr4x4.com/index.php?showtopic=64656&st=0&p=558739entry558739 I've bought swivel overhaul kits to do my front this weekend - will post back if I find anything obvious and if its cured it.

Tibout Posted February 18, 2011 Author Share Posted February 18, 2011 thanks for the reply. just came back from training and as i was getting out of the gate on a slope i just lost my brake the and the landy would not stop until i pull the hand brake. but the thing is that the abs was kicking but it would'nt stop... pretty scary and ideas Quote Link to comment Share on other sites More sharing options...
Guest Posted February 18, 2011 Share Posted February 18, 2011 I had a problem with my ABS kicking in when in slow corners etc and just coming on when not expected, mine turned out to be the tyre pressures were way out hence the wheels turning at different speeds and causing it to kick in and then over heat maybe not that fault as I didn't get brake fade but worth a check.

Tibout Posted February 18, 2011 Author Share Posted February 18, 2011 thanks i'll check it. its scary driving and you don't know if the brakes will work. i've heard removing the abs fuse ubder the bonnet will make the abs stop working but brake will still work normally.i might do that temporarily but i want to get at the bottom of it Quote Link to comment Share on other sites More sharing options...
nrj101 Posted March 20, 2011 Share Posted March 20, 2011 Hi Thierry I have a very similar problem and it almost brown trouser stuff, how Landrover got away with the design is beyond me however, the ABS system arms itself once the vehicle starts to move, and voltage is detected from the sensors, if at any point after that voltage drops after wheel spin up then the ABS believes that the vehicle is in a skid condition and actives the ABS once brake pressure is applied, you then get next to no braking. So we have a fail hazardous condition. You need to find where the signals are being lost, the paper clip test is the first stop. I am toying with making up a little wire harness to monitor the output voltages but at the moment I have stop using the car because of this condition.If anyone is expert on the system further isolation of the fault could be provided in that the systems doesn't record the problem as the system failure that is actually was. That's about a far as I have got with my investigation. Good luck Neil hi i'm having some trouble with the abs system. it's a disco 1 300tdi. so sometimes when i'm driving the abs light comes on but its kind of a very fade lights and turn off after a few seconds. also sometimes the abs over-react specially if im turning at very low speed (like getting in the drive way) i read some articles that if the abs is not working properly it could disable the whole braking system! and also there's a code reading method thingy that we can do to know which one is the faulty ones. anyone know about this? or could it be a loose sensor or dirty one. thanks thierry Quote Link to comment Share on other sites More sharing options...
Range Rover Blues Posted March 22, 2011 Share Posted March 22, 2011 I'm told that Testbook/Rovacom will also report different codes in some conditions to the blink test (paperclip). I've had some codes come up that weren't listed at all. Quote Link to comment Share on other sites More sharing options...
Off Road Toad Posted March 24, 2011 Share Posted March 24, 2011 I had this problem on my 96 disco 300 tdi. very scary, the ABS would cut in at the slightest touch and actually prevent me from stopping the car! So the ABS doesn't always default to a safe mode. I just unplugged mine temporarily while i sorted the problem so as not to kill myself or anyone else. The problem turned out to be a very poorly cv joint and needle roller bearing, new cv and bearing and its good as gold now. Steve Quote Link to comment Share on other sites More sharing options...
Tibout Posted March 24, 2011 Author Share Posted March 24, 2011 Hi guys i still have the issue. i've remove the abs fuse for now and i'm going to rebuild my front hub both side in the near future. but even with no fuse the abs light does'nt come on and the bulb is fine. sometimes it comes on while driving and turn off. i try the paper clip but the warning light did'nt even light up. so i'm not sure what's wrong here Quote Link to comment Share on other sites More sharing options...
Range Rover Blues Posted March 24, 2011 Share Posted March 24, 2011 ECU fault perhaps, I've had one like that. Quote Link to comment Share on other sites More sharing options...
