NOTE:
- When the engine starts during diagnosis, the self-diagnosis function is not cancelled, however, once ignition switch is turned OFF or the vehicle is driven, the DTC display mode is cancelled automatically for safety.
- When the DTC of individual control modules changes in status from current trouble to past trouble, and the trouble is fixed, the DTC will no longer appear in the combination meter if the engine is started three times or more. In this case, read the DTC using the Subaru Select Monitor.
- Because the MT model is not equipped with a TCM, only Receiving DTC is displayed.
