Model with normal meter 

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

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 four times.
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 according to type of control module, receiving DTC, DTC detected or No DTC.

   Control module	Condition	Display
   ECM	Receiving DTC	Trip "A" + "P (Blink)"
   	DTC detected	Trip "A" + "P xxxx"
   	No DTC	Trip "A" + "P --"
   TCM	Receiving DTC	Trip "B" + "P (Blink)"
   	DTC detected	Trip "B" + "P xxxx"
   	No DTC	Trip "B" + "P --"
   VDC CM	Receiving DTC	Trip "A" + "C (Blink)"
   	DTC detected	Trip "A" + "C xxxx"
   	No DTC	Trip "A" + "C --"
   When CAN communication error is occurred	-	"---"

   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.

   2. If the diagnostic trouble code (DTC) is stored, ODO value at occurrence of trouble is displayed.
      NOTE:

      • Diagnostic trouble code (DTC) is stored for up to four cases. If diagnostic trouble code (DTC) is input exceeding four cases, the code is deleted in order starting with the oldest one.
      • When there are more than one diagnostic trouble code (DTC), the code is displayed according to the following conditions and switches every time when the trip meter knob is pressed.
      1. Displayed in the descending order of ODO value.
      2. If the ODO value is the same, displayed in the ascending order of diagnostic trouble code (DTC) value.
