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.
Connecting the Yamaha diagnostic tool
Remove the protective cap, and then connect the Yamaha diagnostic tool to the coupler “1”.

TIP

When the Yamaha diagnostic tool is connected to the vehicle, the operation of the multi-function meter 
and indicators will be different from the normal operation.

 

Yamaha diagnostic tool (US)

90890-03216

Fault diagnosis mode:

Fault codes recorded on the ECU are read, and the contents are 
displayed.

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.

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.
