DTC U0100: F-CAN Malfunction (Powertrain Control Module (PCM)-Motor Control Module (MCM))

NOTE:
  • To verify this is the appropriate troubleshooting procedure, jump the SCS with the HDS and read the flash code, or change the HDS setup to show Honda codes, and read the Honda code.
  • If DTC U0100 is indicated on the HDS, intermittent failure, this system is OK at this time.
  • If the DTC cannot be cleared, do the troubleshooting for DTC U1204.

Check for poor connections or loose terminals at the ECM/PCM and the MCM.
