Diagnosis Procedure
Regarding Wiring Diagram information, refer to TM-126, "Wiring Diagram".
1.CHECK LOCK-UP SELECT SOLENOID VALVE CIRCUIT
Turn ignition switch OFF.
Disconnect TCM connector.
Check resistance between TCM vehicle side harness connector terminal and ground.
2.CHECK HARNESS BETWEEN TCM AND CVT UNIT (LOCK-UP SELECT SOLENOID VALVE) (PART 1)
Disconnect CVT unit connector.
Check continuity between TCM vehicle side harness connector terminal and CVT unit vehicle side harness connector terminal.
3.CHECK HARNESS BETWEEN TCM AND CVT UNIT (LOCK-UP SELECT SOLENOID VALVE) (PART 2)
Check continuity between TCM vehicle side harness connector terminal and ground.
4.CHECK LOCK-UP SELECT SOLENOID VALVE
