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 fuel pulses between the PCM and the navigation for the trip computer function. The F-CAN network uses a communication protocol that transmits data at 500 Kbps.
- If the diagnostic screen reads NG, then diagnostic trouble codes (DTCs) for the F-CAN can be retrieved with a PGM Tester or HDS (Honda Diagnostic System). The data displayed in the ID boxes is for troubleshooting at the factory.
- For more details on troubleshooting the F-CAN, refer to multiplex system.
