X5 abs trac controle and stabilety controle

First check to see if all the wheel speed sensors are reading. If one fails, it will deactivate several of these systems.

ANY TIME ABS LIGHT OR TRAC LIGHT COMING ON THAT MEANS EITHER ONE IS NOT WORKING NOT GETTING NO OR ENOUGH POWER.CHECK ABS FUSE AND RELAYS. IF RELAY AND FUSE OKAY.MAKE SURE YOUR ALTERNATOR VOLTAGE OUT PUT AT BATTERY SHOULD BE 13.5 TO 14.5 VOLTS IF 11.0 VOLTS DUE TO VOLTAGE REGULATOR FAILURE. THAT WILL CAUSE ABS AND TRAC LIGHT TO COME ON.IF ALTERNATOR CHECKS OUT OKAY.TAKE VECHICLE TO GARAGE OR DEALERSHIP THEY HAVE TO SCAN THE ABS BRAKE SYSTEM.

MOST OF THE TIME WHEN TRAC LIGHT AND ABS BRAKE LIGHT COMES ON YOU A HAVE A PROBLEM IN THE ABS AND TRAC SYSTEM.THIS IS A DEALERSHIP FIX. YOU CAN CHECK ABS BRAKE FUSES MAKE SURE IT IS IN TIGHT.AND CHECK FOR FAULTY ABS RELAYS.TO CHECK RELAY LOOK AT RELAY TERMINALS YOU HAVE TERMINAL 86 AND TERMINAL 85.YOU CONNECT TERMINAL 85 TO GROUND AND TERMINAL 86 TO BATTERY POSITIVE TERMINAL.IF RELAY CLICKS WHEN BATTERY VOLTAGE IS APPLIED.RELAY IS WORKING IF YOU HEAR NO CLICK RELAY NO GOOD NEEDS REPLACING.

it could be a bad relay or a blown fuse. check the abs and traction control fuses. There is no way to test a relay but you can replace the abs relay just to be sure. the abs and traction control should share the same relay but you may want to double check. All the fuse and relay locations can be found in your owners manual

Those lights indicate an issue with ABS or traction control systems. In order to properly diagnose the problem the vehicle's codes will need to be read with a scanner.

Generally speaking there is no danger in driving the vehicle but be aware you may not have functioning traction control and/or ABS while those lights are present.

chek power steering reservoir

dont think its computer,but you have one for engine and another for abs/trac and then body computer, scan engine codes and go from there,hope this helps.

change the abs relay in the fuse box under the hood

If you are using an obd2 reader, make sure it has all the updates. If the check engine light is on, is should show up on reader. There is also a ABS light tester as well. It sounds like an error in the ABS/Trac cirucuits. It could be a bad pump or faulty module.

1.Intake air vacuum leak. Check all hoses and bolts for tightness. With the engine running, wiggle all hoses around and listen for a hiss. 2. Change fuel filter, check fuel pressure. 3. Faulty idle control system/sensor.
