    Hi everyone,

    First post here. I registered basically because my dad's currently stuck in Arizona with a broken down truck and we're trying to figure out what is going on. Can anybody offer some advice? The computer is showing 4 messages:

    Check vehicle ECU next stop
    Check brake ECu next top
    Check light control module next stop
    Check climate unit next stop

    All the lights inside the truck are on. When he turns the key, it sounds like the truck is trying to start but cannot. It basically shut down as he was driving.

    I don't know if this piece of information can help but, a few weeks earlier there was a problem with the same truck where all the headlights would go out sometimes when a truck hit a bump in the road. It is actually fixed now and I don't know if this is related to anything but I thought I'd throw it out there.

    Thanks everyone in advance for any help I can get.

    And the truck wasn't hit by lightning?

    * Disconnect the batteries and wait 30 seconds before hooking them back.
    * Check the fuses.
    * Hope it comes back alive.

    Because it's basically all ECUs you might have a communication bus problem which is a bear to diagnose without the shop computer.

    check the ground wire. for all the ecu's to be faulty, they are not grounding correctly. or so it appears to be..

    check your battery connections.also check your pos./neg.connections at alternator.more than likely the ground connections.good luck.

    Does the starter crank? If not, check the battery cable at the starter.

    I have an 05' volvo currently. At one point in time the battery cable that goes directly to the starter had a bad connection. It would shut off EVERYTHING electrical in the truck. Probably not what your up against, but it only takes a second to check.

    Yes it cranks, just doesn't start. Thank you everyone for suggestions I will keep them all in mind so we can figure the problem out.

    I was having the same kind of trouble. The dealership replaced countles parts to no avail. Of course, each time they had the truck, they'd taken care of the problem. They, along with many other dealers/techs/whoever I asked would say check your grounds. Check your battery connections. They, as well as I knew it had to be something with the ground, somewhere. Not likely that all those faults happen all at once, then for a while, everything is ok. I fought this for about four months, not knowing when, or where this thing would finally quit for good. Then, I came across a good ole country dumb hillbilly in Tennessee. He said, "Brang it own in hyer! We-uh seef we cain't figgert ayout fer ye!" Two hours later, and the cost of a couple pieces of jumper wire, and butt-conectors later. My truck is purring like a sewing machine. There is a harness, located against the firewall, and near your brake valve dist. block/hydraulic clutch assist. Within that harness is a plug with about twelve, maybe sixteen wires going into each side. Disconect your battery cables. ALL of them. Get to this plug, and unplug it. The brass pin barrels inside the female side are likely not making connection. Or, in my case, making intermittent connection. Particularly, the larger two of the set. This was showing up as all the codes you'd mentioned. If you have the ability to get deeper into your fault diagnostics on your dash, you might find something along the way that says "J1738datalink/ data transfer erratic", or "J19**datalink/ >>>>>" Cut out the plug, for those two larger wires ONLY, and straight wire them. But, be sure to use the correct guage wiring/butt connectors. And, make absolutely certain that the new connections are sealed up real good. It took me about $4,000 dollars to learn that my problem had a two dollar fix. I asked my country dumb friend (by the way, I'm a red-neck myself. So, don't be gittn' all dignified own me, hyer.) why not replace the plug? He said I could do that if I want to pay to replace the entire wiring harness. And, at that point, "You'd jes be a tradin' a turd fer a turd." The man can't read a stop sign, or spell his own name. But, as you can see, it doesn't make him dumb. Hope this saves you some time, and money.
    edit:
    I'd have posted this sooner, but I wanted to make sure I wouldn't have any more trouble. This took place about seven months ago. In fact, I'd actually forgotten about it until I read this S.O.S. I paid him fifty bucks. He didn't want to take that. He said he hated to see someone pay more money for something that coulda been fixed long before then. I said, if he hadn't have fixed it, it might have cost me another four thousand. So, he took the fifty. And, that was only because it was all I had at the time.

    I was wondering if you could explain to me where the wire is? I can't seem to understand where the wire is. Is it inside the fusebox or ?Its a 2006 volvo, and has the same problems

    Thanks

    Gentelmen! You start all the wrong way

    first of all you've got problems in:VECU, ABS, LCM, Climate unit

    it is so easy to read all active codes in these units with bord computer. Read all codes and post a list of codes here.

    I sugest there is wiring problem of Engine ECU and all the units got J1939 no responce from MID 128 code.

    It is a usuall problrm of battery wiring (thin wire with fuse) under dr.side steps.

    But start with codes first.

    Agree with Pablo.
    Open the driver side step and examine all battery connections - there are 3 thin wires protected by fuses - check those thoroughly. Those power your ecms. Then check the thicker wires where they start and where they end up.

    Also - check connections on the starter. Both ground and positive. There is a wire connected to the starter solenoid that goes to your main fuse box. If that solenoid connection is corroded you may have problems similar to what you describe.
    Hope this helps.
