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 in the step, the display changes to DTC display mode.

• When the self-diagnosis function operates, the warning light, indicator light, and LCD display checks are performed. After this, the buzzer will sound for 0.5 seconds every time the odo/trip meter knob is pressed, and operation checks are performed in the order of meter indicator needle operation, meter indicator needle indication, and LCD. 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.

5. Move on to the “Meter Indicator Needle Operation Check”.

Check meter operation, warning light, indicator light, and LCD.

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 Subaru Select Monitor.

• Only receiving DTC is displayed because MT model is not equipped with TCM.
