So, MrsT had to stop abruptly at a round about this morning, straight after this 'Service ESP' came up on the dash.
I'll pop the code reader in tonight, but googling other forums is a bit rubbish, no real detail on what the problem is.
Generally suggests ABS sensor, with mostly like cause washer broken. :-\
This is about best thread I've found.

Anyone else seen this before?
-
Apparently it's fixed itself, wonder if this connector is a bit loose:

Will investigate tonight.

Did you disturb it when you were doing the oil change?

Was in the area, but not directly near it. Had to take wheel off and drop service flap.

I doubt a super computer could do it, so anything we could get ahold of would be insignificant.
-
generally the abs ring is dirty/rusty or swollen with rust underneth it and or cracked,
poss a sensor but it wouldnt clear itself
-
It’s 2014 plate, it’s generally rust free all over. Don’t ideally want to strip down to be Hub, hoping it’s a sensor.
-
Those washer always break up and cause problems.
-
Looks like that could be the issue, had a frustrating evening investigating. Popped off both front wheels, inspected ABS wiring, all looks good, nice condition, no corrosion or kinks/breakers. Popped off the internal cover a bit and checked the connector inside engine area, as linked above, all good.
No fault codes stored, according to my code reader. :(
(Autel 319)
Although live data all worked ok, but I could find nothing relating to ABS data.
So I've ordered the software that cannot be named here, to see if that gets me more data.
Also need to google how to change said washer.... @andyc - Is Insignia the same? As many more videos for that available.
-
Stops well enough and goes well enough, it's not in limp mode.
-
I doubt that a modern vehicle will have abs rings,most are active sensor bearings nowadays,hopefully some live data will help. Generally speaking if the light goes off at start up it means self test on sensors was good,if it comes on once underway it points to the bearing/abs ring or whatever its taking its readings from

It complains as soon as ignition is on, before engine running/wheels rolling.

Distinct lack of decent resources online, really puts me off older more modern cars. :(
Software that cannot be named, should arrive Friday. If no joy with that, might have to go to the dealer. :o :(

Hope better software will give me fault, most common online aspect suggests sensor going to wheel hub.

The fact that the light is on from start up does point to a sensor fault, what are you trying to rear codes with ?

Tried my Autel 319, which has done 3.2 fine. It also reads live data from Zaf fine.
Also tried ScanMyOpel, via an Android phone and bluetooth adaptor.

Or buy a code reader that can read all codes on all cars. :y
I have one of these (https://www.amazon.co.uk/Launch-Creader-Transmission-Service-Function/dp/B01M9AXSMK/ref=pd_lpo_vtph_263_lp_t_2/257-9014665-0778824?_encoding=UTF8&psc=1&refRID=G78NHG0YSGAMGQ05QRJN) bought secondhand on ebay for £60 and it clearly was hardly used. :y

Trouble with generics that claim "can do xyz" is that they can usually only do it on a subset of vehicles they list once you get beyond drivetrain. Some are better than others. I suspect tunnie needs a recommendation for something that has been tested against a Zaf-C ABS unit....
...or bung a local garage a £20 note, no receipt, for a read.
-
Today I’ll order one I linked to, garages around here want £70 just for a diag. So money well spent, plus Insignia is strong contender for 3.2 replacement.
As even if I get a diag done here, would need another one to clear coders after I’ve changed the sensor.
-

You need to learn how to drop a bung. Can't do that surfing the net ;)

Ordered. Should pay for itself quickly I think.
-
So, the saga continues. :(
Code reader received and updated, once i tracked down a windows laptop capable. I can read all modules correctly and see live data. This is the issue:
ESP on the dash, car runs and drives fine, not in limp mode all instruments working.
(http://i264.photobucket.com/albums/ii177/tunnie_84/ZafiraTourer/Image%20from%20iOS%209.jpg)
Looking in ECBM which I understand is where ABS module is....
(http://i264.photobucket.com/albums/ii177/tunnie_84/ZafiraTourer/Image%20from%20iOS%207.jpg)
There are no codes. :( :-\
(http://i264.photobucket.com/albums/ii177/tunnie_84/ZafiraTourer/Image%20from%20iOS%205.jpg)
But if I clear the ECBM
(http://i264.photobucket.com/albums/ii177/tunnie_84/ZafiraTourer/Image%20from%20iOS%204_1.jpg)
(http://i264.photobucket.com/albums/ii177/tunnie_84/ZafiraTourer/Image%20from%20iOS%202.jpg)
The ABS/Traction lights go out and all is well, until you drive for 15 seconds and its back on. >:(
In Live data, I can see kph of sensors if I roll forwards back, both sides, so the sensors appear fine. I did see this about ABS Pump motor at 0v, so I checked fuse in engine bay, all good. :-\
(http://i264.photobucket.com/albums/ii177/tunnie_84/ZafiraTourer/Image%20from%20iOS%203.jpg)
So I'm at a bit of a loss to the cause, and may have to go to the dealer. :( :-\
-
ABS ECU. Do you get any 'feedback' through the brake pedal when the light comes back on?
-
Try chassis control module ::)
-

No feedback through pedal when light comes on, braking behaves normally.
Try chassis control module ::)
Nothing brake related in there, no codes, no live data relating to braking.
All ABS sensor info is in Electronic Brake Control module, along with ABS pump voltage.
-
The issue isn't necessarily in that module.
Did you reset all the service memories when you changed the oil?
-
Just the oil life, via the dash controls.

The garage didn't reset mine after the oil change, so I did it via the menu on the dash. No problems so I can't see you've done anything that would bring a code up.

Same. Just standard oil reset.
Fact I reset codes for brake module turns light off, suggests fault here.
Also came on couple weeks and few hundred miles after Service.
Shall be admitting defeat and booking it into dealer tomorrow. :(

/me has flashback to Lizzie's wishbone thread

I've troubleshooted it as far as I can go, so have no other option. :(
-
Pedal trick?
-
I assume the dealer will replace various modules and looms etc over several visits and have your pants down ,
Sorry for your loss :'(
(of time and money )
-
As its showing 0v @ the ABS pump, did you pull the multiplug on and see if its getting voltage in, using multimeter? if its getting power, then surely the pump is Donald? If not then can you not chase the wiring back?
As the light's coming on immediately, probably means its not "seeing" a component, rather than that component failing a test of some kind.
Also, have you replaced any relevant fuses (as opposed to just checking them)? I've had a fuse go on the ovlov recently that visually seemed fine, but didn't function.
-
Thanks.
I've just checked the ABS fuse, looked fully intact not even any brown marks to suggest a burn or anything.
Lack of technical info on the Zaf, no idea where the pump even is... let along where looms/plugs run to. I would not be surprised if it's the pump, seen a few go on Insignia forums. :-\
-
is it fitted with a shed dragging hook on the back ?
i had abs problems due to one (not zafira)
very sensitive system , even a blown brake lamp/bulb or dash indicator lamp can throw a spanner in the works
abs pump will be attached to brake lines ,follow them from reservoir
abs pump would have relays and runs when engine is running, constantly
does esp module get data from steering angle sensor ?
-
No burger van towing hook, all other lights working correctly.
Braking works as per normal, so guessing pump is working correctly. :-\

have you tested the abs though ? as in braked hard to check it modulates ,wheels don't lock :-\
the brakes still work,even with a duff pump
-
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 ..... :)
-
The fuse is completely transparent, it’s not like normal ones in Omega internal box.
Half the size, plastic all clear. I’ll pop meter on it tonight to be sure.
-
you did have the engine running when you read the module ? :-\
or the abs pump would read 0 volts ;D

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.

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 :-\

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.

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.

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

Looks easy enough! ::) ;D

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:
(http://i264.photobucket.com/albums/ii177/tunnie_84/ZafiraTourer/Image%20from%20iOS%2010.jpg)
When you say same bus, what exactly do you mean? Scanned all these, under 2.0 no faults stored.
(http://i264.photobucket.com/albums/ii177/tunnie_84/ZafiraTourer/Image%20from%20iOS%207.jpg)
-
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...

I read something about this yesterday and I'm buggered if I can find it again. Turned out to be chafed wiring under the battery tray.

In steering ECU?
Looks like a CAN issue, and be checking the wiring between all these ECUs.
In power steering, yes. But after clearing and then driving only 415 returned.
-
Before condemming any component, just check wiring integrity between them. Also, be aware, with CANBUS, there may not be a direct cable between those, and it might pass through other ECUs on the way, any of which could potentially upset the signal (though unlikely, unless they are in some poorly tested error routine themselves).
Of all the many advantages of CAN, this is the biggest downside.
Hence, the suggestion to go through everything on the same CANBUS (no idea how many the Astra-J/Zaf-C have, previous models had 3 - high speed, medium speed and slow speed). I would imagine ABS would be on high or med speed, but you need to check.
-
So technical knowledge on the Zaf-C is thin on the ground, this thread is better than Zaf forums. So no idea which CANBUS would be which in terms of speed, but....
Yesterday I went through every single module I could under "Zafira-C" - From the park distance module, to radio, transmission, everything. Only area which had codes were power steering module, listed the above.

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.
-
Also fact live data still says 0v to the motor pump as well. :-\
-
OK, still check the connectors though. It probably wont take long, and if its a free fix, you'll be pleased. But sounds like you'll be swapping the part out.
Check if part replacement needs programming in, or if its simply plug and pray. If it does need programming in, those repair services look a lot more appealing ;)

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

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

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.

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

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.
-
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.
-
Good news and better than a failed ABS module! :y
-
People are very quick to condemn the dealers. Diagnosed and fixed in a day, at a reasonable price.
-
Yeah. for a main dealer it’s quite reasonable
-
Glad it was a cheap fix (although many on here would malign £150). :y

Was that Eden Camberley??

Goes to show how good that shitty diags kit is ;)

They have been pretty good over the years on the Astra and Insignia.

Yeah so far in my dealings they have been good, I popped in once for an O-ring. Mechanic came out with a box of ransoms, compared mine and chose right one. No charge.
MOT cost same as local independent, but they also give it a proper wash and health check.
I’m definitely considering an Insignia as 3.2 replacement, even more so now this issue was resolved quite well.
-
What age and mileage are you looking for??
-
He held you to ransom over an 'O' ring? That's not good.
-

Well, it will be when my 3.2 rusts out to be honest. Once that front chassis section goes, I’ll be hunting for one.
But I would have to be Elite spec, with HIDs for starters. :)
