1. SELF-DIAGNOSIS
The self-diagnosis (checking of each meter, warning light, indicator light, illumination, LCD) of combination
meter can be performed in the following procedure.
CAUTION:
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

• Warning light, indicator light, and LCD display checks are performed when self-diagnosis is performed. Af-
ter this, every time the odo/trip meter knob is pressed, the buzzer will sound for 0.5 seconds, and operation
checks for meter operation, meter readings, and the LCD are performed in this order. Turn the ignition switch
to OFF to cancel the self-diagnosis function.
• The self-diagnosis function is not canceled if the engine is started during diagnosis. However, the self-di-
agnosis function is canceled automatically for safety when you start to drive the vehicle.
5) Go to “Check meter indicator operation”.
Check meter operation, warning light, indicator light, and LCD.
