NOTE:

Diagnostic trouble codes which are not listed may be indicated, but they cannot be inspected.
The diagnostic trouble codes are displayed in numerical order. (While performing the inspection, if you want to inspect a diagnostic trouble code of which the number is smaller than the code number you are currently inspecting, terminate the check mode then repeat the inspection from the beginning.)
If a speed signal is input to the instrument cluster (the front wheels are rotated) the input/output check mode will be cancelled.
The diagnostic trouble codes can be fast-forwarded by pushing and holding the odometer/tripmeter switch for 1 second or more.
