DTC CONFIRMATION PROCEDURE

NOTE:
If "DTC CONFIRMATION PROCEDURE" has been previously performed, 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-DIAG RESULTS" mode for "TRANSMISSION".
With GST
Follow the procedure "With CONSULT-III".
Is "P0745" detected?
YES - Go to CVT RE0F10A.
NO - Check intermittent incident. Refer to Intermittent Incident.




Diagnosis Procedure
1.CHECK LINE PRESSURE SOLENOID VALVE CIRCUIT





1. Turn ignition switch OFF.
2. Disconnect TCM harness connector.
3. Check resistance between TCM harness connector F16 terminal
40 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 harness connector.
2. Check continuity between TCM harness connector F16 (A) terminal 40 and CVT unit harness connector F46 (B) terminal 2.





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 harness connector F16 terminal 40 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. Refer to CVT RE0F10A
Is the inspection result normal?
YES - GO TO 3.
NO - Replace transaxle assembly. Refer to Exploded View.
5.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES - Replace TCM. Refer to Exploded View.
NO - Repair or replace damaged parts.




Component Inspection (Line Pressure Solenoid Valve)
1.CHECK LINE PRESSURE SOLENOID VALVE





Check resistance between CVT unit terminal 2 and ground.





Is the inspection result normal?
YES - INSPECTION END
NO - Replace transaxle assembly. Refer to Exploded View.
