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.
