95 e36 328 ABS Light on

[chris2005]

Hi all,

I have a 95 328 with the abs light on,
I have got all the information off autodata and have checked all the resistances and voltages, Relays, modulater,brake pedal switch,speed sensors,and power at the ecu everything is as it says it should be,

The only thing that is not right is when I spin the wheels at 60 rpm approx there is no voltage coming from any of the wheel sensors but the ohms readings are fine,Autodata say i should be getting 0.3v with the meter on alternating current setting but there is nothing happening.

thanks chris.

The ABS light will likely come on if the brake fluid needs changing.

check the ABS sensors in all tires side its 80% form there .either they need clean or unplugged or damaged
or the motor of ABS system not responding ?

Hi .

I have had the pump motor running manually for less than 2 secs it seems fine.
The abs is still working on the car its just the light is on,
Is there any way of clearing the fault codes or does it have to be put on a computer once i have cleaned and checked all the sensors,

Thanks chris.

so maybe you need to reset the system i had air bag light on and a mechanic reset it for 10$ only, so you first check the break oil level and its sensor if not working try to reset the sys. (reset need's computer or reset device)

Turn the ignition switch to position two (2). Connect the pin 7 with 19 (or ground) after the appropriate time (10 sec), Replace the data link connector cap and turn off the ignition switch. Check to see if the reset worked by starting the car and seeing if the lights go out. If they do,

I'd check the fault codes with the five stomp method, found on pelicanparts.com under technical crap, before you go and try and clear them. You might actually have a real problem.

I had the ABS light on my car for a few months now, just got it fixed, turned out to be the two relays in the fuse box, got the dealer to sort if for me, wish I hadn't now, such an easy fix, the relays only cost a few quid each and are dead easy to swam over, if it ain't the relays or the sensors, there is a computer module then the actual pump itself (which costs £800), I've heard that the wiring can go on the actual pump ribbon cable, there is a vid on youtube where the guy rewires it, you've still got the major hassle of removing the pump though
No matter what you try, the ABS system "self tests" whenever you start the car, so if you get the problem sorted, the light should go out right away.

Since you are not reading voltage from any of the wheel sensors, and the resistance is proper, I would assume that the voltmeter is loading them too much to read them. It seems unlikely that all of them have failed.
