  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. Perform the Clear Memory Mode. < Ref. to CLEAR MEMORY MODE . >
  3. Read the diagnostic trouble code (DTC) and check that no DTC is displayed. < Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) . >
    NOTE: If the DTC is displayed on the screen, the trouble is still present. Perform the diagnosis using "Diagnostic Procedure with Diagnostic Trouble Code (DTC)". < Ref. to DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC) . > After solving the DTC, repeat from step  2).
  4. Start the engine, and run the engine at idle for 10 seconds or more.
  5. Read the readiness code using Subaru Select Monitor and check that the concerned DTC is not displayed. For detailed operation procedures, refer to "PC application help for Subaru Select Monitor".
    NOTE:
    • The readiness code shows self-diagnosis status of each DTC. If any DTC is displayed when you select the readiness code, the self-diagnosis of the DTC is not executed or completed. After the self-diagnosis is complete, DTC will no longer be displayed regardless of the diagnostic result.
    • Self-diagnosis is executed every time when the ignition switch is turned to ON. Therefore, even after the self-diagnosis is complete and nothing is displayed on the readiness code display, if you turn the ignition switch to ON again after turning it OFF, some DTCs may be displayed on the readiness code display.
    • After you repair a DTC and perform the Inspection Mode or the drive cycle, use the readiness code to check if the self-diagnosis of the DTC is completed. If the concerned DTC is displayed, the self-diagnosis of the DTC is not complete. Repeat from step  4).
  6. Read the diagnostic trouble code (DTC) and check the DTC. < Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) . >
    NOTE: If the DTC is displayed on the screen, the trouble is still present. Perform the diagnosis using "Diagnostic Procedure with Diagnostic Trouble Code (DTC)". < Ref. to DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC) . > After solving the DTC, repeat from step  2).
