Symptom 2: The Engine Stop Period Is Short
NOTE:
The engine stop period due to Auto Start Stop is the maximum of 120 seconds.
Probable defective cause:
- The battery voltage dropped during Auto Start Stop (state where electrical load is large, battery capacity is low, or battery was degraded).
- Judged the vehicle status as "Auto Start Stop restart conditions are met" (air conditioning gets worse in the vehicle during A/C operation).
- Judged that "the user operates the restart procedure" (braking or steering operation, etc.).
Diagnostic procedure:
- Using the Subaru Select Monitor, perform [Engine stop control] in the active test to stop the engine. Ref. to AUTO START STOP (DIAGNOSTICS)>ACTIVE TEST .
- While stopping the engine using Auto Start Stop, check the appropriate items using the list of check items classified by symptoms. Ref. to AUTO START STOP (DIAGNOSTICS)>DIAGNOSTICS WITH PHENOMENON>INSPECTION>LIST OF CHECK ITEMS CLASSIFIED BY SYMPTOMS .
