WARNING: This page is about a different car, the 2022 Subaru Crosstrek. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- The readiness code shows self-diagnosis status of each DTC. The DTCs displayed here are either not yet self-diagnosed or self-diagnosed but not 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, 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. Perform the inspection mode again.
- For detailed operation procedures, refer to "Help" of application.
