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

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.

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/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 ac-
cording 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 igni-
tion 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.
