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).
1. CHECK POWER SUPPLY AND GROUND CIRCUIT

Display of DTC can be easily performed in odo/trip meter by performing the following procedures.
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/tripmeter 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/tripmeter knob four times.

- Perform the steps described in 2) and 4) within 10 seconds.
- Perform checking DTC with the Subaru Select Monitor basically because malfunction history is displayed with a meter.
- When the engine starts during diagnosis, the self-diagnosis function is not cancelled, however, once turning the ignition switch to OFF or the vehicle starts driving, DTC display mode is cancelled automatically for safety.
- When the DTC display mode operates, {ECM}, {TCM}, {ABS/VDC} is displayed cyclically in this order for every three seconds or every press of the trip knob. DTC is displayed in the following table according to type of control module, receiving DTC, DTC detected, No DTC.
