Finding the abs sensors on a 1999 range rover

Could be that you just have a bad sensor on that side they need to be replaced I don't know if there is anybody that can check the sensor itself that is usually the cheapest place to start in that situation

First one is shorted rough road detection sensor, second one is anti theft sensor

HDC relies on the data from the ABS sensors also, so you should check the ABS sensor cables and that the sensors have not been disturbed (the cables run close to the brake wear sensors). I would bet that they have either disturbed or disconnected the ABS sensor or damaged the cable. It could also be a possibility that they disconnected the sensor, ran the vehicle then realized that it was disconnected, but the fault was triggered, and it may be a case of just having to reset the ABS or HDC system to clear the fault. To reset this fault requires Testbook/T4 or a non-oem software/hardware.

this is a fairly common problem, the most obvious cause is the electrical connection to one or more of the antilock brake sensors on the brake discs ( have you been off road?), if not you have probably had a Antilock sensor failure.

The wheels are fine ,your ABS System
needs to be diagnosed

You do have the lights on your dash-- do you not !!!

ANY dash light indicated a possible vehicle fault

the speedo drive is on this wheel the sensor is on top of the diff output driveshaft ,test the abs sensor with a multimeter for continuety and the connector plug,does the roof vibrate on this one or did the robot work ok on that shift when it was built

Hi

It sounds like the ABS pump has failed, or possibly two unrelated faults, could be the ABS sensor causing the light to come on but might be the fuse in the ABS that has gone. Its worth checking these two things first as they are cheaper.

I have a 1998 Range Rover HSE. The ABS, TC amd Brake light stay on and now I have noticed that it is becoming harder and harder to stop. It literally feels like I dont have any brakes at all. I have to pretty much push the brake petal all the eay down in order to get it to stop. I had the pads and rotors about 6 months ago and I don't know what to do! Help please

the brake will work ok but abs most likely wont most common abs fault i can think of was the abs sensor air gaps to fix gently tap sensors with a hammer while watching to see if they move once gaps are set ok light should go off after roadtest

it could be from many reasons...sometimes even the ABS system will cause this fault or even the Steering position Sensor. if it comes and goes then inspect your height sensors as the early version of the height sensors are getting weak and like melting so it gives wrong reading which cause the fault...offer more info. and you'll get your solution
