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 signals between the PCM and the navigation unit for the trip computer cooling fan function. 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), then you can use the HDS (Honda Diagnostic System) to retrieve the diagnostic trouble codes (DTC) from the F-CAN. The data displayed in the ID boxes is irrelevant.
