Question about 2000 BMW 7 Series

Open Question

Where are the abs relays located on a e38 728i sport, year 2000. keep getting abs and dsc amber warning lights up above 20mph. ABS control module has been away to BBA Remans and deemed perfectly ok, all wheel sensors have been renewed with genuine bmw parts. I have broken open the looms from each sensor connection plug and checked as far as to the wires entering the inside of the vehicle and found no broken or damaged wires or corroded connection plugs. There is no excess play at all in any of the wheel bearings which may cause a to big a gap btween the sensor and hub pickup, so i am now looking to check the abs relays thats if i can eventually find them! if any one can help it would be much appreciated. Many thanks Andy

My traction & stability control warning keeps coming on, not all the time but occaisionally


You have a problem with the abs an there is a code stored in the EBCM - electronic brake control module . It could be any number of thing's from a wheel speed sensor to a wiring problem or the control module or the modulation pump . As long as the light is on the ABS is deactivated . I would take it a qualified ASE certified repair shop that knows ABS systems

Dsc warning light on , bmw e46


Dynamic Stability Control....a derivitave of ABS / Traction control. The control unit that monitors the dynamics will most likely be sensing a difference in the measured wheel speeds. Possibly defective ABS sensor, wiring, ABS exciter ring, ABS module or steering angle sensor. Can also be triggered by wheel spin.
Have a diagnostic scan done ( cost £30 - £50 approx at good local garage) to read the fault codes first. If you get a fault code relating to "ABS module pressure sensor" the module requires replacement (common issue). Used to be a £1400 job, but repair kit now available from dealer for £180 ish and 2 hours to fit.

ABS/ASC module is faulty
CLASSIC ABS FAILURE SYMPTOMS:
- Most of the time, the problem is the ABS module or one of the 4 wheel speed sensors (& sometimes the brake pressure sensor)
- In my 2002 BMW E39 DSC, three orange (warning) cluster display lights lit, ABS, Brake, & DSC
- The 3 warning lights reset when the ignition is turned off, only to repeatedly reappear within minutes of normal driving
- The fault is often intermittent leading you to falsely believe you've resolved the problem (proper diagnosis is important)
- Sometimes the fault only appears when the engine is hot; other times only at speeds over 40 mph
- Carsoft may erroneously show a rear speed sensor failure; but just replacing the speed sensor may make no difference.
- All the work is in correct diagnosis of the problem; parts replacement is trivial (from 1 to six bolts in a few minutes)
- Hence, this BMW E39 ABS 3-warning light DIY will concentrate on understanding and diagnosis of the problem

Abs light illuminated


DTC C0121 will set if the valve relay voltage is low or if the relay supply line is at 12 volts when the ABS control module is not requesting it. This DTC will also set if the ABS control module detects three or more solenoid
valve circuits are open or shorted during the self-test.
Cause(s)
A connector terminal is corroded.
The wiring harness is damaged.
The ground terminal is not conducting properly.
The EBCM is defective.
the relay is internal to ABS unit.

ABS WARNING LIGHT ON VOLVO V70 1997


ABS light comes on with ignition then should go off when you start the car.
If abs sensor does not turn off after disconnecting the battery, then there is a real problem, a faulty sensor or ABS malfunctioning.
When the ABS led comes on immediately after you start the car and stays on usually is one of the relays.
The main one is called surge arrester relay, if it is faulty usually there have been an overvoltage.
There should be two more, usually located behind the black plastic cover of the ABS.
Testing and changing the faulty relay can fix the problem.

If light turns off on startup, and comes back on when you reach some speed, usually you need to check the wheel sensors. You test them unplugging the sensor located behind the wheel and testing it for continuity with a multimeter.
Use Haynes manual to find locations and specs of relays.
Contact a qualified mechanic if you cannot fix it yourself, problems with ABS may compromise safety of the vehicle.
