    U1411 Implausible Fuel Volume Signal ReceivedPossible Causes Setting Conditions
    CAN 'C' Bus circuit is open or shorted to ground
    Cluster module has failed
    FCM has failed
    PCM has failed
    Key on or engine running; and the PCM determined that the Fuel Volume signal it received was implausible.

    This code sets in 1 Trip(s).
    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.
