    U1403-IMPLAUSIBLE FUEL LEVEL SIGNAL
    The fuel level message that the PCM is receiving is implausible. The circuit is continuously monitored.
    Possible Causes
    CAN B OPEN OR SHORTED
    CLUSTER MODULE
    FRONT CONTROL MODULE
    PCM
    Theory of Operation
    The Front Control Module receives a fuel level signal over CAN B from the Cluster Module. Once the message is received from the FCM, it passages the fuel level message via CAN C to the PCM.
    U1411-IMPLAUSIBLE FUEL VOLUME SIGNAL RECEIVED
    The fuel volume message that the PCM is receiving is implausible. The circuit is continuously monitored.
    Possible Causes
    CAN B OPEN OR SHORTED
    CLUSTER MODULE
    FRONT CONTROL MODULE
    PCM
    Theory of Operation
    The Front Control Module receives a fuel volume signal over CAN B from the Cluster Module. Once the message is received from the FCM, it passages the fuel level message via CAN C to the PCM.
    pull fuse 11 in IPM (underhood fuse box) for 30 seconds to clear codes.
