    Hi guys,

     

     

    Family members ve senator ls3 auto my08. It has died and come up safety mode enabled power reduced came up. Pulled a code PO601 Internal Control Module memory check sum error.

     

    Clear the code, disconnect the battery. Starts for few seconds, minutes then dies.

     

    Does anyone have the genuine holden diagnosis procedure for this code what to check etc. Apparently could mean a few things.

     

    Im getting told a lot of mixed things from dead computer, to corrupt file to engine loom etc.

     

    The internal holden documents are quite indepth on what to check step by step anyone have access to this would be greatly appreciated

    Yea, a mate has a VE, have to say does seem they are a definite change to a less “user serviceable” platform.

    Sometimes when they throw heaps of random codes it means the battery os on it’s way out. My dad’s omega did that and one of the work cars (Ford Fiesta) did it recently.

    Seems that is a common things with newer cars these days. If you know someone with a VE swap the battery out to try. No point buying a new one if it isn’t dead.

    This, E38’s are a whiny bitch at the best of times, takes very little for them to chuck a wobbly!

    I’ve heard the same about the E38 ecu glad the VZ LS2 HSV’s used the slightly bigger and been told better E40 ecu.

    Funny how the LS2 in the VE used the E38 same as all other VE’s

    actually I’ve found the E40 to be way more picky than the E38. E55 which is the small Alloytec ECU fitted on the cal head is by far the worst. Whoever thought it was a good idea to mount an ECU filled with tiny hairsized wires to the head and subject it to all the vibrations of each running engine really needs a recalibration…

    some E38’s end up with random corruption of the Flash chip, no one that I know of can say exactly why it happens but could be anything from a bad flash program or voltage spike during cranking with weak battery etc.

    Btw the E40 was a cross over between LS1 pcm and the E38 ECM (has same processor as the LS1 but rest of the architecture is more like an E38) from memory the E40 talks on the VPW bus where as E38 is CAN which is why the VE would use a E38 as they are all CAN bus.
