DIAGNOSIS DISPLAY METHOD
1. Diagnosis display method
The diagnosis is displayed by means of an error code as
shown in the illustration to the left, and by the lights turning on.
When the ignition key switch is turned ON, the lamp lights
once to allow checking for the bulb, and then turns off again if
the status is normal.
With the ignition key switch ON, if an abnormality is detected
when the vehicle is stopped, travelling or performing meterials
handling operations, an error code is displayed and the lamps
turn on as a warning.
When this happens, stop the vehicle immediately and check
the error code.
2. Diagnosis memory display method
To display the diagnosis memory display, there are a method using the hour meter and tilt lever, a method using
the optional display, and a method using a plug-in analyzer.
Here the display method using the hour meter and tilt lever is described.
(1) From the main menu, display the diagnosis memory menu. For how to display the main menu, refer to page
18-30.
(2) A diagnosis No. and error code are displayed each time the knob switch is pressed and released. Each
error code and the time at which it occurred are displayed alternately at 2 second intervals.
Note:
• The maximum number of error codes that can be stored is 10. The smaller the diagnosis No., the more
recent the error is.
• The stored time of an error code appearing just when the ignition key switch is turned ON may be stored
as 0.0.
(3) Connect the matching connector and turn the ignition key switch OFF.
