Hi

I have a problem with a 94 940 Wentworth Est 2.0T - ABS light does not come on when starting (no self test?) also appears that ABS is not functioning (tested on quiet gravelly car park at 25mph+) - and as far as I can see the diagnostic tester in the engine compartment works fine for everything except ABS circuit. So far tried swapping over to a new (s/h) ABS ECU with no luck - tried checking over connections to positive terminal on battery - still no luck - any ideas anyone?

Regards

I have something simillar to your case but...my ABS is working fine.
I have a problem with a ABS system-self testing.
When turning ignition on all the lights flash on, but without ABS lamp.
I've checked a bulb and it is ok.I dont know what to do and where to look in....
Please help.

As far as I know the ABS system can be checked for codes just like the other electronic systems. IIRC, for my 1993 960 you use box 'A', spot '3'. HERE is a general guide on how you can retrieve the codes (please make a donation if you feel that website is worth supporting). As for a list of ABS codes, I don't have a website with that information at the moment. Perhaps on of you guys can 'google' around and post back a website with the ABS code descriptions. I certainly could use it when I try and help others here.

I hope that sets you guys on the right path. Let me know how things work out.

Yes I've used this IIRC diagnosing system and tried to check in socket 3 as you seed but when pushed a buton a diode looks like to "tried"to flash but have no enough power(looks like diagnosing error,or what?).???
But when testing a fuel and ignition system flashing 1-1-1,so I suppose something is wrong with a ABS computer ???
BUT ABS functioning ok when braking (I have no idea ???).
Meybe there is a kind of relay which have to do with testing process and is damaged...???
What you thing...?

Hi Mark

Yes I think you are right there should be a "Surge Protector Relay" with a fuse in the top of it - trouble is I have looked where it should be (on the back of the bracket that holds the ABS ECU ) and there's nothing there !

Anyone have any idea where it could be on a 94/5 940 Wentworth 2.0 Turbo Wagon?

Having the same issues my self, can not find the surge protection relay anywhere, no abs light on dash, abs seems not to be working, but can not find any info on this at all.
