It is necessary to perform the drive cycle listed below if DTC is not found in the Inspection Mode. It is possible to complete diagnosis of the DTC by performing the indicated drive cycle. After the repair for the DTC, perform a necessary drive cycle and make sure the function recovers and the DTC is recorded.
1. PREPARATION FOR DRIVE CYCLE
1. Check that the battery voltage is 12 V or more and fuel remains approx. half [20 — 40 L (5.3 — 10.6 US gal, 4.4 — 8.8 Imp gal)].
2. After performing the diagnostics and Clear Memory Mode, check that no DTC remains. 
3. Check the delivery (test) mode connector is disconnected.
NOTE:
Perform the diagnosis twice if the DTC marked with *. After completing the first diagnosis, stop the engine and perform second diagnosis in same condition.

WARNING:
When performing the drive cycle A on the public road, be very careful of the traffic condition and the safe driving must be the high priority.
1. Check the data in condition column of table by using the Subaru Select Monitor or general scan tool.
NOTE:
• Subaru Select Monitor
For detailed operation procedures, refer to “READ CURRENT DATA FOR ENGINE”.
• General scan tool

3. When the speed reaches to 60 km/h (37 MPH), release accelerator pedal to decrease the speed to 43 km/h (27 MPH) with the gear remained in third. Do not operate the accelerator pedal, brake pedal and clutch pedal at this time.
4. When the speed reaches to 43 km/h (27 MPH), depress accelerator pedal to increase the speed to 60 km/h (37 MPH) with the gear remained in third.
5. When the speed reaches to 60 km/h (37 MPH), release accelerator pedal to decrease the speed to 43 km/h (27 MPH) with the gear remained in third. Do not operate the accelerator pedal, brake pedal and clutch pedal at this time.
6. When the speed reaches to 43 km/h (27 MPH), bring the vehicle to a stop at safe place, then idle.
NOTE:

1. Lift up the vehicle using a garage jack and place it on rigid racks, or drive the vehicle onto free rollers.
WARNING:
• Before lifting up the vehicle, ensure parking brake is applied.
• Do not use a pantograph jack in place of a rigid rack.
• Secure a rope or wire to the front or rear towing hooks to prevent the lateral runout of front wheels.
• Before rotating the wheels, make sure that there is no one in front of the vehicle. Besides while the wheels are rotating, make sure that no one approaches the vehicle front side.
• Make sure that there is nothing around the wheels. For AWD model, pay special attention to all four wheels.
• While servicing, do not depress or release the clutch pedal or accelerator pedal quickly regardless of the engine speed. Quick operation may cause the vehicle to drop off the free roller.
• To prevent the vehicle from slipping due to vibration, do not place anything between rigid rack and the vehicle.

7. Perform the procedures shown on the display screen. If the DTC is not displayed on the display screen, the trouble is resolved.
NOTE:
• For detailed operation procedures, refer to “PC application help for Subaru Select Monitor”.
• Release the parking brake.
• The speed difference between front and rear wheels may light the ABS warning light, but this indicates no malfunctions. When engine control system diagnosis is finished, perform the VDC memory clearance procedure of self-diagnosis function.
