WARNING: When performing inspection mode AJ 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 (DIAGNOSTICS)>CLEAR MEMORY .

Drive 4 times according to the drive pattern described below.
