Diagnostic procedure
- 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)].
- Using the Subaru Select Monitor, clear the memory of [Engine Control System].
- Execute the inspection mode. Ref. to ENGINE (DIAGNOSTICS) >Inspection Mode .NOTE: Perform the inspection mode after warming up the engine except when the engine coolant temperature at engine start is specified.
- 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 "Data Monitor". Ref. to ENGINE (DIAGNOSTICS) >Data Monitor .
- General scan tool
For detailed operation procedures, refer to the general scan tool operation manual.

- While the conditions in the list are satisfied, race the engine at the speed of approx. 2, 500 RPM for 40 seconds or more.
- Start to move the vehicle, then accelerate the vehicle to 50 km/h (31.1 MPH) or more.
- When the speed reaches 50 km/h (31.1 MPH) or more, release the accelerator pedal, the brake pedal and the clutch pedal (MT model) to decelerate the vehicle without shifting the gear. At this time, select an appropriate gear beforehand so that the engine speed falls within the range from 2500 RPM to 1900 RPM for 5 seconds or more.NOTE:
- The vehicle speed does not matter so long as the engine speed can maintain from 2500 RPM to 1900 RPM for 5 seconds or more.
Example: On a downhill grade, it can be performed with a low speed gear and at a low vehicle speed.
- When it is performed with the electrical load such as the air conditioner, etc. turned OFF or the vehicle driven on a downhill grade, the engine speed decreases slowly.
Therefore, the continuous time can be maintained easily.
- The vehicle speed does not matter so long as the engine speed can maintain from 2500 RPM to 1900 RPM for 5 seconds or more.
- Bring the vehicle to a stop in a safe place, and idle it for 5 minutes or more.NOTE: Driving method while vehicle is driven to a stop at safe place is not restricted.
- Read the readiness code of [Engine Control System] using Subaru Select Monitor and check that the concerned DTC is completed. Ref. to ENGINE (DIAGNOSTICS) >All Readiness Diagnostic Code(s) .
- Read the DTC of [Engine Control System] using the Subaru Select Monitor. Ref. to ENGINE (DIAGNOSTICS) >Diagnostic Trouble Code (DTC) .
- With the vehicle idling, read the temporary diagnostic code of DTC using Subaru Select Monitor or general scan tool.NOTE:
- For detailed operation procedures, refer to "Data Monitor". Ref. to ENGINE (DIAGNOSTICS) >Data Monitor .
- In the step 6), if the DTC is not displayed on the Subaru Select Monitor or general scan tool display screen, the trouble is resolved.
