    TCCM error

    Hi All,

    I just received my IIDTool, and had to have a play with it.

    I found this error, that recurs whenever i select low range, is this normal, or is it a real fault that needs to be fixed:

    TCCM-Transfer Case

    P1806-00 (2F) Four-wheel drive high indicator - short circuit to battery

    I've just emailed GAP diagnostics, awaiting a reply, but thought i'd check the forums, i can't find anything by googling.

    cheers

    Does the high range indicator light work properly, ie on in high range and off in low range?

    Whilst the description seems to fit the code, its hard to imagine that the fault might be real considering the indicators work. There may be a different fault for which the wrong code is being reported or there may be no fault at all.

    Given all seems to be working properly, personally I would note the fault, clear it and monitor to see if it returns.

    If there is no actual evidence of a fault, personally I would ignore it until there is some actual real world fault which may never transpire. Maybe bad advice, I don't know, but I've learnt over the years with mine to treat certain computer related things with a degree of scepticism.

    4 years later and I have this error and the high range light is really dull. Not sure I can disassemble the unit and replace the failed LED or maybe it’s the LED driver. Anyhow, it’s a real error for me.

    I have a body control fault_”short circuit or open to ground”. Been there since I got my IIDTool.
    Won’t clear and the mechanic has never mentioned it being a problem. So I don’t worry about it.

    Read somewhere “ If there are no faults then you aren’t driving a Land Rover.”

    Well in my case there is a fault. The LED that indicates high range selected is faulty, however it doesn’t ACTUALLY cause a fault per say. TCCM error
