2. Disconnect the CVT unit connector.

3. Check the line pressure solenoid valve. Refer to TM-423, "Component Inspection (Line Pressure Solenoid Valve)" Is the inspection result normal? YES >> GO TO 2.

NO >> Repair or replace the malfunctioning parts.

2.CHECK LINE PRESSURE

Perform the line pressure test. Refer to TM-382, "Work Procedure".

Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
