1. SELF-DIAGNOSIS
The self-diagnosis (checking of each meter, warn-
ing light, indicator, illumination, LCD, buzzer
sound) of combination meter can be performed in
the following procedure.
1) Turn the ignition switch to ON while turning the
small light to OFF.
2) Step 1) Turn the small light switch to ON within 3
seconds after step 1), then press the odo/tripmeter
knob three times.
3) Turn the small light switch to OFF, and press the
odo/trip knob three times.
4) Turn the small light switch to ON, and press the
odo/trip knob three times.
NOTE:
•Perform the steps described in 2) and 4) within
10 seconds after the ignition switch is turned to ON.
•When pressing the odo/trip meter knob four
times, the display changes to DTC display mode
(ECM, TCM).
tem.>When the self-diagnosis function operates,
the warning light, indicator, and LCD display are
checked, then every press of the odo/trip meter
knob will initiate the operation checks in the order
of meter, illumination and buzzer.
INSPECTION, Combination Meter System.> Turn
the ignition switch to OFF to cancel the self-diagno-
sis function.
•When the engine starts during diagnosis, the
self-diagnosis function is not cancelled, however,
once the vehicle starts driving, the self-diagnosis
function is cancelled automatically for safety.
