What is wrong if the ABS TC and Down Hill warning lights are all on but the vehicle runs just fine?

Answer 1

I had the same problem - the LR dealer changed the sensor on the front left wheel and reset the computer: it was the sensor on wheel

AnswerYou will find that your traction contol has failed or your abs system has a failure, probably a sensor on your wheel or the abs module ,regardless ,it needs attention.my disco is in for same problem at the moment ill keep you posted on the exact findings. Rob... Answerit was the sensor on wheel AnswerRob here again .....back to dealer 4 times ,excuse after excuse,water on sensor, loose sensor ,oh you have a problem....modulator faulty. we will and did replace .three months down the track. the three amigos. abs tc down hill assist lights back on. my opinion? Do not buy any disco that that has those lights on,it seems to me that it is a very common problem with landrover vehicles it costs heaps to fix .2000 odd dollars and landrover pretend its not a problem. Oh i never heard of it before they will say.freelanders also have this problem or one similar.Get real Landrover! A recall is needed, its your brakes that are playing up,iwould love to see or here how many people are having this problem.

AnswerI have a 99 dico II and same problem. No one seems to know what it is or how to fix it. Everyone just wants to charge you to do a diagnose and tell to take it to the dealer. Next time ill buy a cheap SUV. AnswerGenerally when this happens you will need to replace your front pads and rotors with LandRover parts, also for assurance if the code is for a certain sensor it will need to be repalced with the newer style that eleminates the abs sensor connector. The other cause of these lights can be the shuttle valve in the abs modulator. your scan tool schould tell you what is going on. Answertake the vehicle to a Land Rover specialist. not the dealer. have it checked to see the problem. alot of chain part stores have the obdII scanners and they will scan the system for you. most don't charge to do it. they want you to buy the parts there. the common factor of all three lights is the sensor. the next step up is the CPU. One thing to check on all rovers is the electrical grounds. Mine has four different ones. They can loose the ground on one and can cause similar problems. You may also want to check on landroverforums.com. lots of good info. lots of people that are smarter than me. hope it helps. duboff

ANSWER

If you don't use your Traction control, Down hill, you can also turn the damn lights off. I think that I put 2000 bucks into this before I gave up. I simply unscrewed the dash, pulled the plastic cover and put fire resistance fabric in the holes where the lights are. Guess what? No problem.

The real answer

the three amogos are usually caused by the rusted or damaged reluctor ring on one of the wheel hubs, the speed sensor cannot determine the correct wheel speed, it sees 1 wheel going 60 mph and because the sensor thinks the other wheel is going 65 mph, so the computer sends a fault code.....so the warning lights come on..........your abs and traction control are at odds with each other......thinking the wheel is loosing traction or skidding ? So you get the lights.....the hub or speed sensor must be replaced.........the trick is to find out which wheel or hub has the problem, the tolerance is critical with the sensor because it "sees" the wheel speed by a frequency of the wheel spinning by the sensor and reluctor ring........not a job for an amateur repairman.......it's your brakes ....do it right, is it worth risking an accident ? ............ it could cause an accident that is much more expensive than leaving it go, .......and blocking the lights out of the dash module is just plain ignorant the problem still exists that's how someone gets screwed...that rover will be sold to an unsuspecting family that does not know better.......can you say LAWSUIT?
