WARNING: When performing inspection mode AI on a public road, pay sufficient attention to the traffic condition and give the highest priority to safe driving.
NOTE:
  • Perform the inspection mode after warming up the engine except that the engine coolant temperature at engine start is specified  .
  • Even if switched to the hybrid battery save mode under the following conditions, the engine may not start  .
  • Power from HV battery is low and reduction in SOC is slight  .
  • SOC is recovering due to regeneration, etc  .
  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. Using the Subaru Select Monitor, perform the clear memory of [Engine]. Ref. to COMMON (DIAG)>CLEAR MEMORY .
  3. Turn to READY ON.
  4. Press the hybrid mode switch to switch to the hybrid battery save mode.
  5. Wait until the engine stalls during idling. (Engine coolant temperature is 80°C (176°F) or more)
  6. Drive for 20 minutes or more at a constant speed of 80 km/h (50 MPH) or more.
  7. Stop the vehicle.
  8. Read the readiness code of [Engine] using Subaru Select Monitor and check that the concerned self-diagnosis is completed. Ref. to ENGINE (DIAGNOSTICS) (H4DO(HEV))>ALL READINESS DIAGNOSTIC CODE(S) .
  9. Read the temporary code using the Subaru Select Monitor or general scan tool. Ref. to COMMON (DIAG)>DIAGNOSTIC TROUBLE CODE (DTC) .
