Off Road function with Trailer?

Is it possible to reprogram the ECU to allow the Off Road Function with automatic transmission to operate when towing?

    Hi Shaker

    Would it be easier to put something in the trailer plug circuit that fools the computer into thinking there is no trailer , maybe use a relay box that has very low current draw?

    Unplug the trailer while off-road???

    I wonder if it would be as simple as running another earth? So don’t use the neutral in the plug and just run a new neutral from the chassis so you don’t close the trailer plug circuit at all, but still get full function.......?

    i only wonder as if it solely relied on current draw, how could it tell when no lights etc are on? However, if it relied on a complete circuit (continuity) it could test this without applying a load, it would be a TINY current, which a relay in line would still close the circuit as if a trailer was connected??

    IIRC two of the pins complete a circuit that tells the computer a trailer is on the back. Find thos epins and remove the link if this is true!
