ABS light is on, no fault codes

[pklepac]

After coming from MOT (it is called differently in my country though), I have constantly ABS light on.
I have already exchanged both front sensors but the light is still on. Has anyone experienced this strange failure?
Scanning for fault codes brought nothing, testing brakes on gravel road showed that ABS is probably still functional.
Thanks for help.

What did you scan it with - not all scanners can read the ABS modules

On a 90 series there's a way of getting the codes without a reader , shorting out some contacts in the diagnostic plug .Can this be done on a 120 ?

I have scanned it with Techstream and there was nothing, also I saw that all wheel sensors are giving that same speed while driving....

But I assumed it started when guy at MOT did a brake test - as there was no equipment to do it on a roller brake machine, he did it just by hard braking...

Is the light always on now? Does your traction control work?

 

[pklepac]

yes the light is always on, I have not yet tested the traction control...

As a start, have you checked your fuses? It looks like ABS uses two, both in the engine compartment.

61 ABS MTR (40A)

63 ABS SOL (either 30A or 50A depending if your car has VSC - which have you got?)

Could you Techstream contact the ABS module when you did the scan?

I have checked the fuses they looked OK, but I will check them again, the Tecjstream showed me the screens as you can see above...

Now I am trying to figure out what tests I could do with the Techstream...
