NO - Check intermittent incident. Intermittent Incident.




Diagnosis Procedure
Regarding Wiring Diagram information, [1][2]Electrical Diagrams.
1.CHECK PRIMARY SPEED SENSOR





1. Start engine.
2. Check voltage between TCM connector terminals.










3. If OK, check the pulse when vehicle drive.





Is the inspection result normal?
YES - GO TO 7.
NO - 1 - Battery voltage is not supplied: GO TO 2.
NO - 2 - Battery voltage is supplied, but there is a malfunction in the frequency: GO TO 4.
2. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (SENSOR POWER AND SENSOR GROUND) (PART 1)





1. Turn ignition switch OFF.
2. Disconnect TCM connector and CVT unit connector.
3. Check continuity between TCM vehicle side harness connector terminals and CVT unit vehicle side harness connector terminals.






Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace damaged parts.
3. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (SENSOR POWER AND SENSOR GROUND) (PART 2)





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





Is the inspection result normal?
YES - GO TO 6.
NO - Repair or replace damaged parts.
4. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (PRIMARY SPEED SENSOR) (PART 1)





1. Turn ignition switch OFF.
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 5.
NO - Repair or replace damaged parts.
5. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (PRIMARY SPEED SENSOR) (PART 2)





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





Is the inspection result normal?
YES - GO TO 6.
- Repair or replace damaged parts.
6. CHECK THE TCM SHORT
1. Replace with the same type of TCM. Exploded View.
2. Connect each connectors.
3. Perform "DTC CONFIRMATION PROCEDURE". P0715.
Is the "P0715" detected again?
YES - GO TO 7.
NO - Check intermittent incident. Intermittent Incident.
7.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
