5.CHECK CURRENT DATA.

1) Clear the memory using the Subaru Select Monitor or general scan tool. Clear Memory Mode > OPERATION">

2) Start the engine and warm up completely.

3) Using the Subaru Select Monitor, read the values of «VVT Initial Position Learning Value #2» and «VVT Adv. Ang. Amount L» while the vehicle is in stable condition for 30 seconds or more with the engine idling.

NOTE:

For detailed operation procedures, refer to “Current Data Display For Engine”. Subaru Select Monitor">

4) Calculate the values using the following formula. Ignore the unit at this time.

||«VVT Initial Position Learning Value #2» − (60 + «VVT Adv. Ang. Amount L»)|

Is the calculation result less than 10?
