Truck is shutting down intermittently. Using tech tool, the truck is coding U010000, U02A200, U114600. Terminals on ACM appear clean. Have not found any break in wiring as of yet. Going to perform a wiggle test. Just wondering if anyone else has experienced something similar.

Found loose pin going into ACM. It looks like when you plugged harness in the pin was getting pushed back and not making good contact. Repaired pin and the truck has running good. No ACM codes.
