INSPECTION

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 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.
- Warning light, indicator light, and LCD display checks are performed when self-diagnosis is performed. After 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 cancelled if the engine is started during diagnosis. However, the self-diagnosis function is cancelled 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.

NOTE:
- All warning and indicator lights go off.
- The meter indication remains at the same level as "Meter Indicator Needle Indication Check".
- ILL illumination level illuminates at ILL6 level (max. brightness).







2. SYMPTOM CHART

CAUTION: When measuring the voltage and resistance of each control module or sensor, use a tapered pin with a diameter of less than 0.64 mm (0.025 in) in order to avoid poor contact. Do not insert the pin more than 2 mm (0.08 in).

Step 1-6:

9. DTC DISPLAY MODE
The combination meter DTC can be displayed according to the following procedure.

CAUTION: Perform the steps described in 2) through 4) within 10 seconds.

4. Set the lighting switch to tail light or headlight position again, and press the odo/trip meter knob four times.
5. Go to "DTC display mode".
When the DTC display mode operates, the display is changed every 3 seconds or {ECM}, {TCM}, {ABS/VDC} is displayed cyclically in this order for every press of the trip knob. DTC is displayed in the following table according to type of control module, receiving DTC, DTC detected or No DTC.







NOTE:
- When the engine starts during diagnosis, the self-diagnosis function is not cancelled, however, once ignition switch is turned OFF or the vehicle is driven, the DTC display mode is cancelled automatically for safety.
- 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. In this case, read the DTC using the Subaru Select Monitor.
- Because the MT model is not equipped with a TCM, only "Receiving DTC" is displayed.
