    Hello VXL gang!

    I'm trying to source some info for my Dads Astra SRi... It's a 1.9 CDTi, and lately I've replaced the discs and pads front and back, the lower suspension wishbones, repaired the EGR valve and the Anti-roll bar drop links (PHEW!!)

    Next and nearly the final thing is... THE ESP LIGHT!! It continually stays on...

    I have a mate that connected into the Astra's brain via a Snap-On code reader and asked why it was all upset, and got quite a few alarms up... Two of which may explain why the ESP light is glowing nicely...

    P0650 CAN-Bus No Communication with CIM (Steering Column Module) C-003
    U2139 CAN-Bus No Communication with CIM (Steering Column Module) C-003

    Also P1614 and P1616...

    Am I right that the steering wheel angle sensor is connected to the CIM unit, so if there is no comms between either the ESP light comes on? wierd as the horn, indicators and other bits of junk work.... Any ideas anybody?

    Thanks

    Karl

    P0650 and U2139 would indicate a faulty control unit either the CIM or the ABS (complete unit) more than likely the ABS, both are security coded to the vehicle so 2nd hand isn't an option. the other 2 codes relate to immobilizer B3055 is usually stored aswell,this is a CIM software issue which can only be updated by your vauxhall dealer,usually the car would have failed to crank at some stage to store these codes.

    All fitting together!

    Hello!
    Thanks for the reply... Completley right! It has failed a couple of times to crank over (apparantly). A bit more information I managed to glem was that 6 months ago my Dad had been contacted by Vx that his car had a recall... "something about a horn not working"... Fits in nicely really! :)

    Apart with "I'd better get it to Vx" as his reply!! I did read that the units were paired (prob. to stop us from fixing the faults ourselves)

    Thanks again

    Karl

    After a year, still no further forward! Now to resurrect a thread from the dead!
    Dad (at the time) went back to Vx, had the CIM unit updated, and still no difference. Still the ESP light on, and now (of course) the law has changed about warning lights will fail the MOT.

    The original faults were...

    P0650 CAN-Bus No Communication with CIM (Steering Column Module) C-003
    U2139 CAN-Bus No Communication with CIM (Steering Column Module) C-003


    So, left to me to sort out. Since having dealings with Vx in the past I'm loathe to give them any money... I've been ripped off by them before, and at a huge expensive! The root cause was down to a £12 sensor which I found in the end!!

    Anyway, back to it...

    Can anybody shed a bit more light on this stuff? If the CIM unit was at fault, then surely the steering would be heavy as hell, and the indicators, horn et all would not work..?
    As for the ABS, then that would generate a fault code if that was upset??

    Darn this is giving me a headache!

    Any help guys would be great!!

    steering will not be heavy because of faulty CIM unit, it is just part of the vehicle computer system, doesnt actually run the PAS.
    Also, just out of interest, (and my reson for replying to this) what sensor did you change? just for future reference! ;)

    Aha... Thanks for that!
    Well, the sensor I'm referring to was on another car (sorry if I may of miss-leaded you there reading the previous replies). It was a Calibra I bought off from my Dad. It was fine to begin with, then the problems started. So, into the local Vx it went, changed all sorts of junk over a period of time, I found it was the engine temperature sensor was duff. It was a eureka moment I had in work when I was working on something similar... But each time they replaced a part, I asked for the old part to be fitted back as clearly that wasn't the fault. They assured me it was....
    So as you can imagine, them telling dear ol' Pa the ABS unit may be duff envisages an immediate knee jerk reaction of "bol***ks!"

    Of course they may be right...

    Have you tried new abs sensors on each wheel? I believe these may be a part of the whole hub, but may be worth seeing if you can buy just the sensors?

    It could be! I believe from reading up on the different types of ESP systems out there, the ABS unit handles pretty much everything! There is a separate algorithm that handles the ESP work, and another which handles the ABS work... all in one package! I believe in some versions all 4 corners are hooked up to sensors so the system knows whats going on...

    But as there is a communication issue with talking to the CIM unit.. I keep thinking that is all upset! I've found a unit on fleeBay, BUT, I don't have Tech2 to change any of the coded parameters... I don't think OP-COM can do this...Bah!!

    One unit I found is for £1900!!! Cheaper for Vx to do it, but he just doesn't have that sort of wedge!!

    OPCOM can do your CIM change quite nicely.

    Well, that's outstanding news! And now you've said that, I've just found a "How-to" guide on how to do it on this here very forum! http://www.vauxhallownersnetwork.co.uk/index.php?attachments/opcom-new-cim-programming-pdf.3704/

    I hope this thread will help anybody else who has this problem....

    Next thing is trying to wrestle the car away from him! (As 1. it's his pride and joy 2. He needs it for work!)
    As long as the P/N is the same, there shouldn't be too much hassle in buying one from eBay?

    Thanks again!!
