    HDC System fault, Special programs not available

    Hi Guys,
    had to disconnect the battery today as it went flat. So disconnected it and charged it up then reconnected it.


    Car started fine but noticed it had all sorts of system faults afterwards.


    Special programs not available & cant select any.



    Transmission range change not available

    Noticed the hi range and low range lights are flashing


    Also the green mountain symbol on left guage is lit as is the orange system fault symbol under the temp guage.


    I tried resetting by lock / unlock the car 3 times. No good.


    any thoughts? Do I need to reset something?


    hope somebody has some wisdom on this one.
    cheers
    Peter

    Hi Peter
    Have you tried a hard reset. If not would be worth a try details in the Frequently Asked Questions section.
    Cheers

    As per this
    ow to Hard Reset
    Removing the key from the ignition and let the vehicle sit at least 5 minutes to lets all the ECUs go to sleep so they won't be damaged by the reset. Then, undo the battery -ve terminal, then undo the battery +ve terminal and touch the two cables together to short them (You may have to place a screwdriver to get the 2 cables to touch). This is known as a hard reset.

    **PLEASE** take care not to drop & short the cables together on the battery & create an arc as this will lead to damage. Note that this is touching the CABLES together, and does not involve the battery at all!

    If you have a dual battery system installed, you MUST remove the negative terminal off all auxiliary batteries BEFORE you touch the cranking battery terminals.

    And only after you have done the HARD RESET and reconnected both cranking battery terminals, then you can reconnect the auxiliary battery negative terminals.
    Cheers
    Tony

    That was taken from the FAQ section on the forum. Several threads on this, seems to clear a lot of battery related faults.
    Good luck

    How charged up is the battery? Voltage can be high enough to start the engine but too low to prevent the disabling of various functions to conserve the battery.

    Pressing the suspension raise button is the usual method of clearing the flashing lights unless the fault (eg low battery) is still current.

    Sorry Peter, I couldn't resist it. You are having a bad day!

    Aside from the battery perhaps being on its way out, could be a small draw on the battery like here:

    yeah mate tis the way it goes. Anyway off tto apple Store at Carindale tomorrow for a refurb iphone 5.


    As for the issue with the D3 I have no idea at all. I can still drive it ok just no off road functions. Will give MR a call on Monday and see what they have to say about it.


    Obviously when I disconnected the battery I have upset something or the other.


    cheers

    ok seems the fault has been cured. Rad that if you put it into offroad height you can then cycle though the special programs. Tried it and yes it worked!


    Could select all programs and select low range. I then lowered it to normal height and special programs all worked. All I can think is that upon putting the car into offroad height it forces an ECU load to clear any corrupted data sitting in the ECU buffers.


    Now to see how the battery goes . . . .
