With CONSULT
With GST
Follow the procedure "With CONSULT".
Diagnosis Procedure
Regarding Wiring Diagram information, refer to TM-126, "Wiring Diagram".
1.CHECK PRIMARY SPEED SENSOR
3. If OK, check the pulse when vehicle drive.
2. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (SENSOR POWER AND SENSOR GROUND) (PART 1)
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.
