Instrument Panel, Gauges and Warning Indicators: Testing and Inspection
Combination Meter SystemINSPECTION
1. SELF-DIAGNOSIS
The self-diagnosis (checking of each meter, warning light, indicator, illumination, LCD, buzzer sound) of combination 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 position.
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.
- When the self-diagnosis function operates, the warning light, indicator, and LCD display checks are performed. After this, operation checks are performed in the order of meter, illumination, and buzzer for each press of the odo/trip meter knob button. Turn the ignition switch to OFF to cancel the self-diagnosis 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 deactivated automatically for safety.

3. Turn the lighting switch to OFF, and press the odo/trip meter knob four times.
4. Set the lighting switch to tail light or headlight position again, and press the odo/tripmeter knob four times.
NOTE:
- Perform the steps described in 2) and 4) within 10 seconds.
- When the engine starts during diagnosis, the self-diagnosis function is not cancelled, however, once turning the ignition switch to OFF or the vehicle starts driving, DTC display mode is cancelled automatically for safety.
- When the DTC display mode operates, {ECM}, {TCM}, {ABS/VDC} is displayed cyclically in this order for every three seconds or every press of the trip knob. DTC is displayed in the following table according to type of control module, receiving DTC, DTC detected, No DTC.
- Past problems are displayed on the DTC display. When the DTC of individual control modules changes in status from current trouble to past trouble, and the trouble is fixed, the DTC will no longer appear in the combination meter if the engine is started three times or more.
