    Default HELP - Engine Electronics Control Lamp Problems

    As a newcomer to this owners club and having owned an 2002 Vectra C 1.8 LS for about 7 relatively trouble free months (apart from a new water pump) , I am now experiencing an engine electronic system problem that has resulted in calls to the RAC twice in the last week. I wonder if any members have experienced similar problems (apologies if covered elsewhere in previous threads) that could perhaps offer some advice. The problems first started about 2weeks ago in the following chronological sequence:

    Monday - Unable to start the car due to what appeared to be a flat battery after the car had stood overnight after being regularly driven previously. Started engine with jump leads from my other car, following all appropriate guidelines in the owner’s manual. Had battery checked, told was OK. (Green “eye” visible etc. voltage drop under start load acceptable, terminal voltage OK)

    Thursday – Having driven for over 10 miles in the afternoon (and similar distance in the morning) , the car was parked with ignition off but lights on, waiting to pick my children up from school. The car would not start again with symptoms similar to flat battery again. RAC called who immediately identified a slightly loose connection on one of the battery terminals. After tightening both battery connections the engine started first time.

    Friday – Again having driven the car to and from work, on the journey to collect the kids, my wife indicated left and then immediately right at a junction and as she was indicating the Engine Electronics control light briefly lit and then went off.

    Monday – Driving in slow moving traffic, the alternator lamp, the engine electronics lamp and the ABS lamp all lit and stayed on. All the dash board dials registered zero (i.e. tachometer, speedometer, fuel gauge and temperature gauge). The car was driven for a further few miles but after stopping to drop one of the children at school, the engine would not start again!! Every time the ignition was tried, the three warning lights were lit. After several attempts (having left several minutes between each) the ignition was turned to position 2, the warning lights were lit and then went out. Once out, the car started first time OK. RAC attended again but was unable to interrogate the OBD as their diagnostic system could not read Vectra C’s. The car was taken to a Vauxhall main dealer who said there were no errors logged in the memory and therefore could not diagnose the problem.

    Ever since that Friday, the car has now behaved identically each day. Every time I come to back it out of the drive in the mornings, the engine electronics control lamp and the ABS lamp light up briefly and then go off within about a minute of starting the car. On the journey to the schools, it occurs usually twice again and then throughout the rest of the day and often into the evening, nothing occurs until the following morning.

    I have also noticed that the heated rear window will only work for a couple of minutes before the same warning lights come on, the heated rear window switches off and the lights go off again. This morning whilst trying to evaluate all the symptoms, I experienced the loss of all dashboard dial readings again, even though I was stationary in the drive.

    Has any one experienced similar problems and if so what actions were necessary to rectify them? I have read elsewhere that it might be as a consequence of a faulty ECU, ABS bus connector, CIM failure or the Body Control Module but any advice or assistance on this problem would be gratefully received.

    Sorry for the length of this posting but I have tried to include as much detail as possible.

    Well 1st of all to the site mate, I'm sorry you're having such a bad time with your car.

    If you are having the same symptoms every morning, could you leave it overnight at the Dealers and then in the morning they will be able to put Tech2 on it and see if any fault codes are thrown up to try and diagnose the problem.

    How does the car drive when these symptoms arise?

    Does the engine run smoothly?

    It sounds like it is a multi-system problem rather than just affecting one module, perhaps a problem with the CanBus itself causing a corruption of the data and thus causing several modules to re-boot, so as to speak?

    I'm sure that there'll be others along soon with more ideas.

    Tim

    Thanks for the welcome Tim. Although I am new to this owner's club, I have owned and driven Vauxhall's for 25 years and it has only been my wife's last two Vectra's that have given us any real trouble.

    I can not argue with your logic about dropping the car off at the dealers overnight in order for them to interrogate it on the Tech 2 in the morning. I am reluctant to do this as we purchased the car with a 12 month warranty but it is with a third party warranty company rather than with the actual dealer we purchased the car from and therefore would prefer to be in a position where we can advise work to be carried out in a specific area (for example the CIM if the consensus of opinion is that this is likely to be at fault) in order to maximize the cover we have under this warranty. If we left the car at dealers, we would have to cover these initial costs ourselves, with no guarantees of getting them refunded through the warranty.

    I am hoping that a few others may advise areas to concentrate on through their own similar experience.

    If you can give any more info, that'd really help.

    When this happens, can you operate other things, ie front and rear wipers? Lights? Electric mirrors? Steering wheel radio controls?

    . On the vae-c the battery is not constantly charged only when it's told to. There is a recall on some alternators as they are faulty units and it may be worth contacting a dealer to see if your car is on the recall list with one of the affected units. HTH

    Hi Tim

    Everything works as normal with the car. It drives the same, the indicators work (although the audible click doesn't occur), the brake lights work etc. All that happens is the alternator light and ABS light come on and all the dials drop to zero (sometimes with the engine management symbol, occasionally not). Obviously if stopped, the engine won't re-start while in this mode.

    I'm taking it to a Vauxhall Diagnostics Specialist on Friday (thankfully at the request of the dealer) so I will post back when I hear more.

    I appreciate everyone's input, its been a help, thank you.

    That's worth noting too - thank you.

    You don't happen to know what error code would be reported by the Tech2?

    ...don't worry - I'm hoping to claim for all of this under warranty.
