DTC CONFIRMATION PROCEDURE
CAUTION: Always drive vehicle at a safe speed.
NOTE: Immediately after performing any "DTC CONFIRMATION PROCEDURE", always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT
VEHICLE SPEED : 40 km/h (25 MPH) or more
RANGE : "D" position
Diagnosis Procedure
1.CHECK LINE PRESSURE
Perform line pressure test. Refer to TM-162, "Inspection and Judgment".
2.CHECK SECONDARY PRESSURE SENSOR SYSTEM
Check secondary pressure sensor system. Refer to TM-85, "Description".
3.CHECK PRIMARY PRESSURE SENSOR SYSTEM
Check primary pressure sensor system. Refer to TM-90, "Description".
4.CHECK LINE PRESSURE SOLENOID VALVE
5.CHECK SECONDARY PRESSURE SOLENOID VALVE
Check secondary pressure solenoid valve. Refer to TM-89, "Component Inspection (Secondary Pressure Solenoid Valve)".
6.CHECK STEP MOTOR SYSTEM
Check step motor system. Refer to TM-109, "Description".
7.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
Component Inspection (Line Pressure Solenoid Valve)
1.CHECK LINE PRESSURE SOLENOID VALVE
Check resistance between CVT unit connector terminal and ground.
Component Inspection (Secondary Pressure Solenoid Valve)
1.CHECK SECONDARY PRESSURE SOLENOID VALVE
Check resistance between CVT unit connector terminal and ground.
