    Help automatic gear faults

    Hello everyone.

    Normal driving in town suddenly came on two lamps M and S , after a few meters the engine stopped working . I checked fuses and f24 - burned (Responsible for power supply to the computer gear and engine computer) After examination by Nanokom i saw
    P0743 Solenoid valve lockup clutch monitoring (S/C to Ground or O/C)

    What does it mean? and Where to look for problem?

    Thanks in advance

    Short circuit to ground or open circuit on the lock up clutch solenoid.


    First thing I would do is check the harness where it runs beside the gearbox for any signs of rubbing and damage. From there you'll need to check with a multimeter to see if you can isolate the cause of the short.

    I've attached the LR diagnostic information for the fault. The "&!" should be an Ohm symbol. C193/32 refers to a connector and pin number which can be identified using the Connector Views section of the Electrical Library pdf from the RAVE CD. If you don't have a copy of RAVE - you can support the forum by getting a CD from here

    cheers

    Check the loom where it passes trough the steel clamp on top of the transfer case. They rub through and short to ground, many hour to find it.

    Good result, can you tell how you found that, did you remove the centre section?

    Cheers, Jerry
