All warning lights come up

    I have the problem with my Commodore Acclaim 1998.
    Actually, it started a few weeks ago. While driving, a few warning lights (ABS, Traction Control, Batteries, Engine and Oil), come on and stay up for some time.
    After it was going for few days, air-conditioner stopped working. I went to AC master, he told me that AC fluid and some small detail needs to be replaced. He done it and I got my car back. However, problem with lighting was still there and I found that when Oil light comes on (together with all other lights I have listed above) – air-conditioner does not work, when only other lights come on but Oil stays off AC is working normally.
    I went to Holden Dealer service.
    First, I’ve been told that my key-reader and remote control needs to be replaced and it will fix all this problem. They did it - problem was still there. They told me that now ABS module needs to be replaced and may be, also, wiring hub (?). Just another few hundreds bucks and they cannot guarantee that will fix initial problem. So, I’ve decided to go to another place (as approach of replacing every car detail until the problem go, looks to me as a quite expensive option). In another place, I’ve been told that problem is very simple to fix - just alternator needs to be replaced (as it gives 11-12V and it should give 13-14V). They replaced alternator and… problem still there. Now they telling me that problem appear to be huge… So far, I’ve paid $500 just for R&D (research & development).
    Is any one had such problem before?
    It appears that lights go on when engine warms up and off when it cools down. On hot days, they may come on straight away after engine starts and they never go off. AC doesn’t work occasionally.

    Thank You for help!

    I always thought it was quite common for all new cars dash lights to illuminate on startup for 10 seconds or so. Not all, but alot of stuff came up on all the cars i remember.

    Just don't pay anymore money unless they can guarantee their work. Try heaps of different places and don't let them rip you off.

    This is a common failure in commodore. The ABS Module is faulty, when the module faults it causes exactly the symptoms you describe.
    When the fault is present the vehicle serial data bus is grounded, this causes all the warning lights to come on, & will stop the AC working as the pressure etc cannot be read because the serial data is down.
    replacing the module will fix it. a new module retail is about $650
    plus half an hour to fit.

    Cheers Rob

    I have same problem

    After experiencing an almost identical problem with all warning lamps coming on - (even had the aircon regassed because initially I thought it might be an aircon problem) - I have just had my Caprice WH V8 2000 to the auto electrician (after two failed tries at Holden Dealer) where he diagnosed the ABS module to be faulty and needing replacement at a cost of approximately $850.00. I was disappointed as the car has only done 100,000 kays and I thought it would only be a "loose" wire or something and I consider this to be quite a major repair. The weird thing was that Holden couldn't find out the problem after two "looks" at it. Is it possible that they don't know about these sort of "common" problems at the dealer/service level?

    depends on the level of expertise in the workshop.
    its a very common thing & shouldnt be too hard to pick up
    depending of course on the fault being present when they saw the car, its very hard to fix something if its not broken.
    another point would be if the fault isnt there at the time of inspection how much time can they spend checking it?
    still in saying that there should have been enough exposure to the problem at all dealers by now to recognise it,
    no offense intended to any other dealer staff.

    Cheers Rob

    Same problem as well...

    :mad: Yup, very frustrating!! Its happening to my VT S Series II as well. Warning lights come up (ABS, oil, Air bag, Engine) and the Air-Con stops working, although the Air-con sometimes continues to work when the problem is there. The problem started ocurring at 125,000 k's.
    Holden believe it is an ABS module fault. Sound like they are correct from this forum... They advised the cost to replace it is about $800.
    Is it possible to buy this part from Holden spare parts or a wrecker and then install it myself or is something that only Holden can do? (i.e. do you need some sort of software/terminal to set it up or do you need to disconnect and bleed ABS lines...etc?)

    Its a Holden job, They need to bleed breaks and a few other things plus you get warrenty if they do it. Worth the monies. This is why I never ticked the ABS box when I brought mine.

    VX Gen3 All panel lights on engine stalls

    Hi Dr Bob

    I am having a similar problem ,engine stalls , wont start for 5 mins , then everything is fine. Also hard to start when cold and low rough idle ,power light goes off ,then fine
    after warmup. No codes logged at the ECU except " no data communication
    with the body control module".

    Have cleaned the IAC valve , cleaned all sensor connectors etc.

    A very fustrating and sometimes dangerous problem. Only 58,000 on the clock.

    Does this sound like the ABS control module.???

    I own a 1998 VT Acclaim and I have had the ABS and Trac Off lights coming on about 70% of trips. I have just had this problem fixed by a mechanic who simply cleaned the point contacts at the wheels and made sure they were a firm tight fit. Apparently these points set off both lights if they are not a good contact. I had previously had the ABS module replaced and this did not solve the problem.

    Now Much !

    My VT Calais has just been diagnosed with exactly the same problem, the only difference is that I was quoted $1600 NZ for the replacement part from a Holden dealer in Auckland. Is this the normal price or is there somewhere where I can purchase the ABS computer module at a cheaper price.

    Hi all,

    Also have similar problem (but no ABS).

    Get the Engine Management System light flikkering most of the time, and very rarely the temparture light (even on cold starts).

    Twice when I washed the car got almost all lights flashing, though fixed itself up.

    Also climate control doesnt seem to be working (no heat).

    Will get auto electrician to have a look at.

    Any suggestions greatly appreciated

    Cheers

    Similar Problem

    My ABS light comes on now and then, but after turning the car off for a few seconds and then turning it back on the problem stops. My aircon has also stopped working. Could it be a smaller version of this bigger problem???

    VT Calais
    I have a 1998 VT Calais 111kkm's with same problem. The ABS light alone comes on for a sec and then Traction Control, followed by Power Trans and sometimes by the engine light and aircon. This usually happens while driving and lasts between 1-5minutes and then everything goes back to normal. Engine completely shut down on one occasion (luckly not on freeway).

    I took out both ABS fuses and now the ABS light and Traction Control stay on all the time. The engine, power trans and aircon warnings still come on very briefly while driving but only stay on for about 1 second. Could it be that other serial bus problems cause ABS to crash and take down the whole bus down for 5minutes?

    Went to holden dealer and paid $55 for them to tell me that the ABS needs replacing at the cost of $900. Wouldn't listen when I explained to them that the problem persisted even without the ABS... Don't tell us how to suck eggs and all such crap. They told me they performed a diagnostic on the ABS module. But I now wonder if they have the tools, the knowledge or the expertise to do that properly or if they just read the error code from the BCM and decide that the ABS is stuffed.

    Ironically, I used to work at the testing department at Robert Bosch (the makers of the ABS module). Too bad I never considered sneaking away with the schematics and test plans for the ABS module.

    VT Calais Warning Lights

    I have the same problem, all lights come on,ABS, air con, cruise control, traction, and others stop working, did any one finally come up with a fix on this problem, as I cannot afford to go down the pay, as the dealer experiments with your car fault finding technique.
