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 .
- 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)].
- Using the Subaru Select Monitor, perform the clear memory of [Engine]. Ref. to COMMON (DIAG)>CLEAR MEMORY .
- Turn to READY ON.
- Press the hybrid mode switch to switch to the hybrid battery save mode.
- Wait until the engine stalls during idling. (Engine coolant temperature is 80°C (176°F) or more)
- Drive for 20 minutes or more at a constant speed of 80 km/h (50 MPH) or more.
- Stop the vehicle.
- 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) .
- Read the temporary code using the Subaru Select Monitor or general scan tool. Ref. to COMMON (DIAG)>DIAGNOSTIC TROUBLE CODE (DTC) .
