This only happens in 4-low when I try to switch to manual and hold the jeep in 1st gear. Goes into limp mode which requires me to shut off the jeep and restart it to get it back into park. When it happens the SERV 4WD and Transmission fault lights will come on and stay on.
Once I stop and restart the jeep and return to 4-low 1st gear, the lights stay lit but it is driveable....sometimes for a while, sometimes I have to do this multiple times on a trail.
Once I switch back to 4 high or 2 wheel drive and drive for 20 minutes the fault lights go out.
Codes all point to a sensor problem? U0403-00, U0402-00, P1DB6-00, P215C-00, P0607-00, P1412-00, B1642-15, B1646-15, P1514-87, U1440
