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.
1. Turn the ignition switch to ON while turning the small light to OFF.
2. Turn the small light switch to ON within 3 seconds after step 1), then press the odo/trip meter 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).
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 cancelled automatically for safety.

5. CHECK VDCCM
Step 1-2:
6. CHECK ENGINE CONTROL MODULE (ECM)
Step 1-2:
7. CHECK FUEL LEVEL SENSOR
Step 1-6:
8. CHECK ENGINE COOLANT TEMPERATURE SENSOR
Step 1-2:
9. COMMUNICATION ERROR DISPLAY
When the following error code is displayed in the odo/trip meter, inspect the communication circuit since the communication failure is generated between each control module. Basic Diagnostic Procedure
10. DTC DISPLAY MODE
When DTC display mode is operated, {ECM}, {TCM}, {ABS/VDC} is displayed repeatedly in this order by pressing the trip knob. DTC is displayed in the following table according to type of control module, receiving DTC, DTC detected, No DTC. If CAN communication has some trouble, "-----" is displayed.
