Abs and traction control lamps coming on on dash intermitantly can also feel a very slight vibration through the brake pedal when the ignition switched on have had the car put on diagnostic scanner and it faulted rear right sensor which was replaced but fault still the same the car is a mitsubishi shogun 3.2 did 2004 model year

You need to have your brakes inspected by a professional. The lights indicate that ABS and traction control are not working...although brakes will work without these features, a humming noise can indicate more problems to come.

Hi First I suggest that you get a diagonostic check on ABS system. and then a visual inspection of the brakes. Warped brake rotors do not make noice, but the steering will start to judder when brakes applied at around speeds from 40 up . Possible cause that the vehile picked up something from road such as nylon/ plastic/stone Mike

a quick test is to disconnect the sensor connector hook up and ohm meter to the sensor connector on the hub side not the engine side and spin the hub if the resistance rises and falls you're most likely ok if the resistance reads 0 or infinite you have found the bad sensor..this won't always be the case but it's a good start in the right direction

Number of possibilities. Most likely culprit is wheel bearings. Have these checked. Big heavy car and wheel bearings do take a hammering on XK and XJ's. Once they go, the wheel speed sensors are out of line with the tracking ring and a fault code is thrown. As the TCS uses the same sensor, this also throws a fault. Next in line is the ABS unit (it's hardly ever the main block, but ECU itself, companies on the net offer rebuilt units. Finally it can be the ABS pump unit - but the fault codes will show if this is the case - or you can pull the pump unit plug out of the ABS unit and see if it has continuity with a multimeter - should be a low number of ohms. 8 times out of 10, it is wheel bearing.
