NOTE: Perform the inspection mode after warming up the engine except that the engine coolant temperature at engine start is specified.

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 .
With the ignition switch ON (engine stopped), read the values in [Engine Coolant Temperature] and [Intake Air Temp.]. Ref. to COMMON (diag)>DATA MONITOR .
If the values from step 3) satisfy the following conditions, idle the engine for two minutes or more.
Condition:

|Engine coolant temperature - Intake air temperature| ≤ 5°C (9°F)
NOTE:
- If the conditions are not satisfied, turn the ignition switch to OFF and wait until the parameters are satisfied.
- Hold the select lever in "P" range or "N" range at idling.
Read the temporary code using the Subaru Select Monitor or general scan tool. Ref. to COMMON (diag)>DIAGNOSTIC TROUBLE CODE (DTC) .
