Good point, well presented.

Also have you tried the pedal trick?

Also, if you can't find the abs block, you aren't looking.

Follow the brake lines from the servo and report back  :y

Engine running and taken for a drive, while live data running. Still 0 volts displayed, at all times.

No pedal trick, besides don't see how that can give anything above what code reader I have.

Still think it is the ABS pump, as it never says any positive volts, speed sensor data, everything else looks good.

You keep saying you've checked the fuse by looking at ...  since when have your eyes been electrically continuous ???  Put a meter on the fuse and check for continuity .. it is the ONLY way to correctly check a fuse ... how do you know the visible bit has not broken off one of the legs in the corner ???

 :o :o

Might not be that, but for the sake of doing a job PROPERLY... it would rule it out once and for all ...  I can see you being very pissed off if a new fuse were to fix the problem ..... :)

Tested with MultiMeter, all good for ABS fuses.  :y

I agree. I'd be pointing at the abs pump/controller unit. 2nd hand one an option?

Shouldn't be hard to change.

Live data tests, key 0v here I think  :-\



Everything else checks out ok.

ABS Module looks mega expensive to replace, DIY videos for ZafB look scary and not something I would want to do myself.

Thanks both  :y

Yeah will need to call them, as they don't list anything 2013 or newer.

Would like to get dealer to confirm my diagnosis though, perhaps visit Serek for this job.  If I could source another unit, to fit and replace at the same time.

I read the ecutesting webpage earlier today. They seem to be saying that it's a common fault due to a sensor that was external being placed internally on later units. Therefore, if the unit is replaced like for like, the fault will reoccur.
I don't buy it. I've heard nothing about it being a common fault.

I can find very little online about it, does not appear that common post Zaf-B, some say about rev counter failing (like Omega ABS pump issues) vibration/loss of power, (again Zaf-B) but everything on mine works fine.

More confusing is still lack of fault codes anywhere.  :-\

Mine's the same setup so, of course, I'll be interested in the outcome.
