NOTE:
Check codes which are not listed may be indicated, but they cannot be
inspected.
The check codes are displayed in numerical order. (While performing the
inspection, if you want to inspect a check code with a number 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 wheels are rotated),
the input/output check mode will be cancelled.
The check codes can be fast-forwarded by pushing and holding the
odometer/tripmeter switch for 1 s or more.
