    2017 KW t680 isx15 cm2350 460k miles
    Sitting idling with the tractor brakes set and out of nowhere the speedometer shoots up to 10-15 mph then back down. Error warning pops up on the dash that says "Warning: air brakes in engage while driving" or something along those lines and the transmission says there is a fault. It kicks me onto drive line and ruins a reset when it happens. Any ideas what it might be?

    A whole different animal but IHC 9670,s had Deutch plugs through the floor. When they got water in them the the turn signs could make other gauges sweep and such.
    Some KW's a bit older leaked water into the dash on the left side and caused some problems.
