1. SELF-DIAGNOSIS

The self-diagnosis (checking of each meter, warning light, indicator, illumination, LCD, buzzer sound) of com-
bination meter can be performed in the following procedure.

NOTE:
Perform the steps described in 2) through 4) within 10 seconds.
1) Within 3 seconds after turning the ignition switch to ON, set the lighting switch to tail light or headlight po-
sition.
2) Press the odo/trip meter knob three times.
3) Turn the lighting switch to OFF, and press the odo/trip meter knob three times.
4) Set the lighting switch to tail light or headlight position again, and press the odo/trip meter knob three
times.

NOTE:
• When pressing the odo/trip meter knob four times, the display changes to DTC display mode. <Ref. to IDI-
18, DTC DISPLAY MODE, INSPECTION, Combination Meter System.>
• When the self-diagnosis function operates, the warning light, indicator, and LCD display checks are per-
formed. After this, operation checks are performed in the order of meter, illumination, and buzzer for each
press of the odo/trip meter knob button. <Ref. to IDI-6, LIST OF SELF-DIAGNOSIS MODE OPERATION, IN-
SPECTION, Combination Meter System.> Turn the ignition switch to OFF to cancel the self-diagnosis func-
tion.
• When the engine starts during diagnosis, the self-diagnosis function is not cancelled, however, once the
vehicle starts driving, the self-diagnosis function is deactivated automatically for safety.
