Diagnostic Trouble Code Chart

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 the speed signal is put into the instrument cluster (the front
wheels are rotated) while a code other than DTC 00 is display, 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.
