F-CAN System Link

F-CAN System Link

F-CAN (Fast Controller Area Network) passes information between processors on the network. For example, the F-CAN network is used to pass charging system or "illumination cancel" signals. The F-CAN network uses a communication protocol that transmits data at 500 Kbps.

- If the diagnostic screen below reads NG with the ignition switch ON (II), you can use the HDS (HONDA Diagnostic System) to retrieve the diagnostic trouble codes (DTCs) from the F-CAN. The data displayed in the ID boxes is irrelevant.
- For more details on troubleshooting the F-CAN, refer to the multiplex system.

NOTE: If this is red "IF4", then the F-CAN link to the gauge control module may be malfunctioning.
