This code will turn on the MIL (Malfunction Indicator Lamp) Vehicle Application: 2005 Jeep Grand Cherokee Laredo 4.7L, Vin N, Eng Cfg V8
Customer Concern: Has 11 codes. U0101, U110C, U0121, P0480, U1120, U0103, U1411, U110E, P000B, U0100, U0002. At this time there is a no crank condition.
Tests/Procedures: 1. Clear the codes and see what comes back. These are all communication codes.
2. Disconnect the modules one at a time when it is acting up and see when the communication comes back.
Potential Causes: Controller Area Network (CAN) C Module
Tech Tips: On this vehicle it turned out the Occupant Restraint Controller (ORC) which is on the Controller Area Network (CAN) B bus was actually causing the problem. It was also taking down the Controller Area Network (CAN) C bus at times.
I hope this helps.
