YCC-S (Yamaha Chip Controlled-Shift) SYSTEM (FJR1300AS
only)
8-196
*If the main switch is turned to “OFF”, the fault code number will disappear from the display and will not
be displayed again when the main switch is turned back to “ON”. Therefore, use the engine stop switch
to stop the engine, not the main switch. If the fault code number has disappeared, activate the diagnos-
tic mode and select diagnostic code No. Sh_ _61. The fault code numbers can be confirmed in the mal-
function history. Refer to “Diagnostic code table (Diagnostic code No. Sh_ _61)”.

TROUBLESHOOTING METHOD
NOTE:
If the engine trouble indicator “1”, YCC-S indica-
tor “2”, and engine trouble warning light “3” all
come on, malfunctions have been detected in
both the fuel injection system and the YCC-S
system. If this occurs, the fault codes for the fuel
injection system take priority over those for the
YCC-S system, so only the fuel injection system
fault codes will appear in the multi-function dis-
play. The fault codes for the YCC-S system will
be displayed in the multi-function display after all
of the fault codes for the fuel injection system
have been deleted using the reinstatement
method.
The YCC-S indicator and warning light come
on.
