DTC CONFIRMATION PROCEDURE
NOTE: 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
ATF TEMP SEN : 1.0 - 2.0 V
If it is out of range, drive the vehicle to decrease the voltage (warm up the fluid) or stop engine to increase the voltage (cool down the fluid)
4. Start engine and wait for at least 5 consecutive seconds.
With GST
Follow the procedure "With CONSULT".
Diagnosis Procedure
Regarding Wiring Diagram information, refer to TM-126, "Wiring Diagram".
1.CHECK INPUT SIGNAL
2.CHECK POWER AND SENSOR GROUND
Check voltage between TCM terminals.
3.CHECK HARNESS BETWEEN TCM AND CVT UNIT (SECONDARY PRESSURE SENSOR) (PART 1)
4.CHECK HARNESS BETWEEN TCM AND CVT UNIT (SECONDARY PRESSURE SENSOR) (PART 2)
Check continuity between TCM vehicle side harness connector terminal and ground.
5.CHECK HARNESS BETWEEN TCM AND CVT UNIT (SENSOR POWER AND SENSOR GROUND) (PART 1)
6.CHECK HARNESS BETWEEN TCM AND CVT UNIT (SENSOR POWER AND SENSOR GROUND) (PART 2)
Check continuity between TCM vehicle side harness connector terminals and ground.
7.CHECK TCM
8.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
