  • CAN B open or shorted
  • Cluster module
  • Front control module
  • PCM

Theory of Operation
The Front Control Module isn't receiving a fuel volume signal over CAN B from the Cluster Module. The FCM has to send the PCM a fuel volume signal over CAN C. The signal the FCM sends over CAN C is implausible.


Unfortunately, to properly diagnose this problem, you will need access to advanced diagnostic tools. It isn't something easily fixed by a do-it-yourself'er.
