F-CAN System Link
F-CAN (Fast Controller Area Network) passes
i n f o r m a t i o n between processors on the network. For
example, the F-CAN network is used to pass fuel pulses
between the PCM and the navigation unit for the trip
computer function. The F-CAN network uses a
c o m m u n i c a t i o n protocol that transmits data at
500 Kbps.
• If the diagnostic screen below reads NG w i t h the
ignition switch ON (II), then diagnostic trouble codes
(DTCs) for the F-CAN can be retrieved w i t h the HDS
(Honda Diagnostic System). The data displayed in the
ID boxes is irrelevant.
• For more details on t r o u b l e s h o o t i n g the F-CAN, refer
