• Actuator operation
To operate the actuator, set the start/engine stop switch from“ ” to “ ”.
8. Turn the main switch to “OFF” to cancel the diagnostic mode.
TIP
Information about each diagnostic code number is organized in this manual as follows:
• If a diagnostic code number has a corresponding fault code number, the information is shown in
“TROUBLESHOOTING DETAILS”. (Refer to “TROUBLESHOOTING DETAILS” on page 8-40.)
• If a diagnostic code number does not have a corresponding fault code number, the information is
shown in “DIAGNOSTIC CODE TABLE”. (Refer to “SELF-DIAGNOSTIC FUNCTION AND DIAG-
NOSTIC CODE TABLE” on page 9-5.)
9. Connect the wire harness coupler to the fuel pump.

YAMAHA DIAGNOSTIC TOOL
This model uses the Yamaha diagnostic tool to identify malfunctions.
For information about using the Yamaha diagnostic tool, refer to the operation manual that is
included with the tool.
Features of the Yamaha diagnostic tool
You can use the Yamaha diagnostic tool to identify malfunctions quicker than with conventional
methods.
By connecting the adapter interface, which is connected to the USB port of a computer, to a vehicle’s
ECU using the communication cable, you can display information that is necessary for identifying mal-
functions and for maintenance to display on the computer. The displayed information includes the sen-
sor output data and information recorded in the ECU.
Functions of the Yamaha diagnostic tool
However, the diagnostic tool cannot be used to freely change the basic vehicle functions, such as
adjusting the ignition timing.

Fault diagnosis mode: Fault codes recorded on the ECU are read, and the contents are
displayed.
The freeze frame data (FFD) is the operation data when a mal-
function was detected. This data can be used to identify when
the malfunction occurred and check the engine conditions and
running conditions when it occurred.
Function diagnostic mode: Check the operation of the output value of each sensor and actu-
ator.
Inspection mode: Determine whether each sensor or actuator is functioning prop-
erly.
CO adjustment mode: Adjust the concentration of CO admissions during idling.
Monitoring mode: Displays a graph of sensor output values for actual operating
conditions.
Logging mode: Records and saves the sensor output value in actual driving con-
ditions.
View log: Displays the logging data.
ECU rewrite: If necessary, the ECU is rewritten using ECU rewrite data provid-
ed by Yamaha.
Ignition timing adjustment, etc. cannot be changed from the vehi-
cle’s original state.
