Driving to work today, both the service 4wd and traction control lights on the dash came on and the light for the 4wd selector switch is off. I shut the engine off and restarted, the dash indicators were off and the 4wd switch light was on. I checked for codes with my Tech2 abd found these: U1026- loss of class 2 communication with ATC, C0244- PCM delivered torque malfunction, U1064- loss of BCM/DIM/SBM communication. Any ideas where to start looking? This is the second time in 400 miles that the U codes were in memory, the first for the C0244 code.
