MAINTENANCE OF THE MCU
Checking the MCU
1. Check:
• Terminals “1” of the MCU
Cracks/damages
→
Replace the MCU.
• Terminals “2” of the MCU couplers
Connection defective, contaminated, come-
off
→
Correct or clean.
NOTE:
If the MCU couplers are clogged with mud or dirt,
clean with compressed air.

MCU (motor control unit) SELF-DIAGNOSTIC FUNCTION
The MCU (motor control unit) is equipped with a self-diagnostic function in order to ensure that the
YCC-S system is operating normally. If this function detects a malfunction in the YCC-S system, it im-
mediately operates the system under substitute characteristics and lights the YCC-S indicator and
warning light to alert the rider that a malfunction has occurred in the system. Once a malfunction has
been detected, a fault code is stored in the memory of the MCU (motor control unit). After the engine
has been stopped, the lowest fault code number appears on the odometer/tripmeter/fuel reserve trip-
meter LCD. Once a fault code has been displayed, it remains stored in the memory of the MCU (motor
control unit) until it is deleted.
NOTE:
If the engine trouble indicator “1”, YCC-S indicator “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 display. 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.
1. Check the gear position sensor.
Refer to “CHECKING THE GEAR
POSITION SENSOR (FJR13AE
only)” on page 8-235 and “AD-
JUSTING THE GEAR POSITION
SENSOR (FJR13AE only)” on page
5-11.
Replace the gear position sensor.
2. Check the gear position setting.
Refer to “Diagnostic code table (Di-
agnostic code No. Sh_ _65)”.
Replace the MCU (motor control unit).
