Main problem is there is no communication to abs module.
Any help would be much appreciated.
Thanks

[ruffles1986]

if ABS unit not work don't have speed signal, this take speed signal from abs sensor on wheels. Have you comunication with ABS control unit?
Check terminals 1 and 14 +12V (Line 30) check fuses too
Check terminal 20 +12V (Line 15) check fuse
Check terminals 13 and 26 GND (Line 31)
Check Can Bus-Hi Voltage on terminal 23 with Key ON must be 2,5 - 2,7V
Check Can Bus-Low Voltage on terminal 21 with Key ON must be 2,2 - 2,4V
Check Impedance On Can Bus, between terminals 23 and 21 must be 55 - 65 Ohm

If wiring is OK and you can comunicate with ABS Module programming them

unplug and replug ABS pump connector

[marusca]

in many cases CIm it's problem...

Problem solved. It was a faulty speed sensor which is located on the passanger side wheel. I would of thought it would come up as a fault code, not have no communication with abs module!!

All them faults now cleared then

how did you discover that

[ZIE]

sorry for late reply, i had a second hand speed sensor, thought to try eliminate another possibility and hey presto it came to life.

[ZIE]

also all faults cleared
