  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. Using the Subaru Select Monitor, perform the clear memory of [Engine Control System]. Ref. to COMMON (DIAGNOSTICS)>CLEAR MEMORY .
  3. With the ignition switch ON (engine stopped), read the values in [Engine Coolant Temperature 1] and [Intake Air Temp.]. Ref. to COMMON (DIAGNOSTICS)>DATA MONITOR .
  4. If the values from step 3) satisfy the following conditions, idle the engine for two minutes or more.
    CAUTION: 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.
  5. Drive according to the drive pattern described below.

    (A) Vehicle speed
    (B) Elapsed time
    (1) Idle the engine for 2 minutes or more.
    (2) Drive for a total period of 15 minutes or more at a speed of 80 km/h (50 MPH) or more.
    (3) Stop the vehicle and idle for 30 seconds or more.
    (4) Drive for 30 seconds or more at a constant speed of 80 km/h (50 MPH) or more.
    (5) Stop the vehicle and idle for 30 seconds or more.
    (6) Drive for 30 seconds or more at a constant speed of 80 km/h (50 MPH) or more.
    (7) Stop the vehicle and idle for 30 seconds.
    NOTE:
    • In pattern (2), it is acceptable to decelerate to less than 80 km/h (50 MPH) or to stop the vehicle depending on the traffic conditions. Drive the vehicle at 80 km/h (50 MPH) or more until the total driving time reaches or exceeds 15 minutes.
    • 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.
    • If the ignition switch is turned to OFF during inspection mode F, perform this driving cycle again after satisfying the conditions listed in the table.
  6. Read the readiness code of [Engine Control System] using Subaru Select Monitor and check that the concerned self-diagnosis is completed. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>ALL READINESS DIAGNOSTIC CODE(S) .
  7. Read the pending code using the Subaru Select Monitor or general scan tool. Ref. to COMMON (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
