Note

•  In this mode, it is possible to verify the items in the following chart.

Check Code Table

Check code	Check item	Related items
08	TNS relay	•  Lights-on reminder warning alarm •  Each illumination light
12	Speedometer	Speedometer
13	Tachometer	Tachometer
14	Buzzer	Buzzer
16	Fuel-level warning light	Fuel-level warning light
22	Fuel gauge sender unit	Fuel gauge
23	Fuel gauge	Fuel gauge
25	Water temperature gauge	Water temperature gauge
26	•  Odometer/tripmeter (LCD) •  Warning and indicator light	•  Odometer/tripmeter (LCD) •  Warning and indicator light
51*	—	—
55	Panel light control switch (dimmer switch)	Panel light control switch (dimmer switch)

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.
