Thread: M & S Warning lights

    M & S Warning lights

    Discovery #
    When I stop and select reverse (Automatic)the S & M lights start blicking.
    This also happens if the vehicle is idling for a short time
    I have been told that this could be a battery problem. I have checked the batteries they seem ok
    Turning the engine off and re starting clears the problem
    Any advice appreciated

    I had this - and what I could figure out it was a battery problem - I had been fiddling around to see if an old battery would be okay, - but it happened on start up and the D in the window flashed as well and the gearbox stayed in 3rd. Fortunately I was only a few k's from home.

    If you disconnect your battery - check the voltage - then leave it overnight then re check the voltage to see how much it's dropped - Or of course it might be easier to pop into a battery place and have them test it.

    If it isn't the battery then further investigation is needed - you may have to take it in to see if there are any fault codes in the computer

    Check the CDL or High-Low lever is properly engaged. Limp home mode should try and reset on startup after (I think) about 20 minutes or the time it takes for the ECU bits to discharge or what ever. Restart the vehicle and see what happens,

    Balgowlah,
    It could be a faulty battery, best to get it load tested.
    It could also be the Gear Position switch on the gearbox or what happened to mine was the wiring loom above the t/box had 2 wires cut through because of a metal "p" clip had rubbed through.

    Balgowah - dealing with S & M lights myself. They're on all the time and the car is permanently in limp home mode. Did you manage to sort out what was causing your problem? Cheers, Lloyd. PS Mine's a 2003MY Disco TD5.
