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-III
1. Turn ignition switch ON.
2. Start engine and wait at least 5 seconds.
3. Perform "Self Diagnostic Results" in "TRANSMISSION".
With GST
Follow the procedure "With CONSULT-III".
Is "P0745" detected?
YES - Go to P0745.
NO - Check intermittent incident. Intermittent Incident.




Diagnosis Procedure
Regarding Wiring Diagram information, [1][2]Electrical Diagrams.
1.CHECK LINE PRESSURE SOLENOID VALVE CIRCUIT





1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check resistance between TCM vehicle side harness connector terminal and ground.





Is the inspection result normal?
YES - GO TO 5.
NO - GO TO 2.
2.CHECK HARNESS BETWEEN TCM AND CVT UNIT (LINE PRESSURE SOLENOID VALVE) (PART 1)





1. Disconnect CVT unit connector.
2. Check continuity between TCM vehicle side harness connector terminal and CVT unit vehicle side harness connector terminal.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace damaged parts.
3.CHECK HARNESS BETWEEN TCM AND CVT UNIT (LINE PRESSURE SOLENOID VALVE) (PART 2)





Check continuity between TCM vehicle side harness connector terminal and ground.





Is the inspection result normal?
YES - GO TO 4.
NO - Repair or replace damaged parts.
4.CHECK LINE PRESSURE SOLENOID VALVE
Check line pressure solenoid valve. P0745
Is the inspection result normal?
