NOTE:

There is no given transition time between idling and cruising.
Driving at constant speed only on a downhill causes smaller engine load and may result in failure to obtain a right diagnostic result.
When the engine stops while performing drive cycle F, perform it again from the state of procedure 1).

Perform the Clear Memory Mode. Refer to CLEAR MEMORY MODE
With the ignition switch ON (engine stopped), read the value in «Coolant Temp.» and «Intake Air Temp.». Refer to READ CURRENT DATA FOR ENGINE (NORMAL MODE) , OPERATION, Subaru Select Monitor
If the values from step 2) satisfy the following conditions, idle the engine for one minute.
Condition:

|Engine coolant temperature - Intake air temperature| ≤ 5°C (9°F)
NOTE:
- If the conditions are not satisfied, turn the ignition switch to OFF and wait until the parameters are satisfied.
- Hold the select lever in "P" range or "N" range at idling.

- The Subaru Select Monitor screen does not change after the evaporative system leak test is complete or when the test is aborted by turning off the ignition switch.
- If «Test conditions are not correct» display appears, check that the values in «Coolant Temp.» and «Intake Air Temp.» are within the specified range using Subaru Select Monitor. If the conditions are satisfied, make the necessary preparation for the drive cycle again. Refer to PREPARATION FOR DRIVE CYCLE , PROCEDURE, Drive Cycle
After 30 minutes passed from the start of step 14), click the [OK] button to return to the «Evaporative System Leak Test» display.
Click buttons until the «OBD Menu» display appears, then select {Result of on-board monitor test}.

In the {Result of on-board monitor test}, check TID $C1 - $CA of MID $3C.

RESULT OF ON-BOARD MONITOR TEST

Display	Details	Remarks
$0000 is stored in all Val.	During the evaporative system leak test, the test conditions were not met and the test was canceled.	Once the test conditions are met, perform the test again.
All Val. are stored with values and OK is set to all the results.	Evaporative system leak test is completed correctly.	While the ignition switch is ON, read the pending code using the Subaru Select Monitor.
Some results were no good.	The evaporative system leak test completed successfully but the results were faulty.	While the ignition switch is ON, read the pending code using the Subaru Select Monitor.

When the evaporative system leak test is completed correctly, read the pending code with the ignition switch turned to ON position. If the DTC is recorded, check the appropriate DTC. Refer to OPERATION , Read Diagnostic Trouble Code (DTC)
NOTE: The pending code will be cleared by turning ignition switch to OFF.

Idle the engine for 15 minutes or more.
Turn the ignition switch to OFF.
After 10 hours passed from the start of step 2), read the pending code using the Subaru Select Monitor. Refer to OPERATION , Read Diagnostic Trouble Code (DTC)
