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

I think this is fairly common with ABS module faults?  :-\

The Omega dosnt  show a fault code, but we all know what's wrong because the speedo fails.  ;) 

When the ABS light came on last year on my BMW, the fault code showed the nearside sensor was faulty. I wasted a lot of time, energy and money trying different sensors, switching them over etc, and I changed the wheel bearing with the reluctor ring.  ::)  I even got Kevin Wood involved who got his oscilloscope out!  :o but couldn't get a result!  :-X  ;D

Eventually I sent off the ABS module to BBA Reman who confirmed it was totally goosed and unrepairable!  :(

Least you had some codes, but looks like ABS unit could be sent off/replaced.

No reports of that fault here:

https://www.honestjohn.co.uk/carbycar/vauxhall/astra-j-2009/good/

Nothing here for ESP, other than no button, which is odd as there is a TC button.

https://www.honestjohn.co.uk/carbycar/vauxhall/zafira-c-2012/good/

Interestingly, numerous "odd" electrical failures are listed .. for both the Zafira and the Astra ....

Yes but it sent me off on a wild goose chase!  :(

I'd be inclined (if possible) to take the ABS module off, leaving the pump in situ. It might be easy like my Beemer or a bitch like the Omega.  :-\ Then send it off for test and hopefully repair.  ;)

But as you have it booked in at Vauxhall, you may as well follow through with that now.  :y

Although you have the weekend to look at it and scratch your head!  ;D

off side rear for mine... Ultimately sold/exported for bits because I got pissed off with it having changed the sensor twice.

When you say 'no pedal trick'...

Have you actually tried?

It looks a right pain to remove, I’m hoping dealer confirms it is ABS pump. Then either use local garage to remove old one and I/they send it off to be reconditioned and refitted.

Or I source another and take it to Serek’s for replace and fit in one go

Yes, either no worky or no codes. Given all code readers say no codes either, think it’s the latter.

The way CAN works is you want to check all ECUs on the same bus.  So go round all of them.

Plus, as its ESP, check things like steering angle live data is plausible.

Yes read that in some posts, it comes back with changing live data:



When you say same bus, what exactly do you mean? Scanned all these, under 2.0 no faults stored.

Hummm. Although, scanning through my photos I took of fault scanning.

In two separate scans the wheel position is -1.08 deg, either I parked it exactly same way or that value did not change. Will double check this shortly.

Scratch that, just tested and it’s giving various figures positive and negative. Eg bit of left hand wheel and it’s at 145.46 deg.

Breakthrough

Found inside the "Power Steering Control Module" a bunch of codes, thanks to TB for suggesting all modules, I cleared them and ABS EBCM error to clear dash error. Went for a drive, ESP came back on and went back to power steering module, had this code:

U0415: Invalid Data Received from Electronic Brake Control Module.

Off to Google....

EBCM itself had no codes...
