Lower the vehicle, and pull ST, which were set in step 4), into the vehicle.
Connect the Subaru Select Monitor to the data link connector and read the current data. Refer to READ CURRENT DATA .

Perform the transfer clutch pressure test in the same manner as the line pressure test.

NOTE:

Do not perform the transfer clutch pressure test for 5 seconds or more at a time. Doing so will make the engine oil and ATF deteriorate and the clutch and brake to be adversely affected.
After performing the transfer clutch pressure test, be sure to cool down the engine for at least one minute with the select lever set in the "P" or "N" range, and at an idle speed of 1, 200 RPM or less.
Adjust the accelerator pedal opening angle in order to obtain the "T/F solenoid target pressure" displayed on the Subaru Select Monitor.
