Also fact live data still says 0v to the motor pump as well. 

What does it say on a working one?  Is that the return pump? If so, that would only be activated under antilock conditions.

Oh.

I can't test a working one, unless you mean try the Omega?

Your reader might not do all ECUs.  So get a set of schematics from somewhere, and pour over them.  Pretty certain you can get a day subscription to GM's EU TIS, because we can't recommend dodgy copies of the software here, can we.


That said, does sound likely its the ABS causing a problem.  But if the ABS/ESP is working, I would defo be checking the connectors etc before condemming anything.

It's not, another weekend test was taking it on the by-pass.

I stamped on the brakes at 70mph, easily locked up the fronts, with no pedal feedback.

so 0 volts ,abs pump not working
did you find the abs relay , mentioned many posts ago

Yes, the large 60amp one in the engine bay, there was another fuse as well 25amp Micro2 fuse in the engine bay too.

The larger one had a cover to remove on top, so you could visually inspect as well.

Both tested with a multi-meter, both had number "close to one" as per research suggested it should.

Also to add, it's a new multimeter, not old POS one I had before.

relay , not fuse

I don't know what live data your reader provides, hence I was asking/suggesting if its the return pump, I suspect it would read 0 under normal conditions.


It is a different unit to the Omega ones, so the comparison is meaningless.

It allows me to pick a bunch of data, as seen in photos. So reasonable enough, speed sensor etc, must be about 25 values of live data ABS system.

Hummmm relay, book tells me about fuses, but not relays. As always with this car, technical data is low online. 

Presume it would be a relay in the engine bay fuse box?

Forums are full of ZafB owners with same lights on and me and it's all down to ABS control module, sod all on ZafC but perhaps they are only just starting to age now.

[tunnie]

So I can't find overview on ZafC, but found one for ZafB

There are no ABS relays, only fuses.

So, it’s all fixed. Turns out it was a washer inside the wheel hub, which had failed. I had seen it as a possible cause, but I could not get any codes to suggest this.

I’m £150 lighter as a result, but happy it’s all resolved.

[Sir Tigger KC]

Good news and better than a failed ABS module! 

[STEMO]

People are very quick to condemn the dealers. Diagnosed and fixed in a day, at a reasonable price.

[tunnie]

Yeah. for a main dealer it’s quite reasonable

[Viral_Jim]

Glad it was a cheap fix (although many on here would malign £150).

Was that Eden Camberley??
