DTC CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

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 (PART 1)

1.  Start the engine.
2.  Maintain the following condition for 5 seconds or more.
3.  Stop the vehicle.
4.  Check the first trip DTC.

2.CHECK DTC DETECTION (PART 2)

With CONSULT

1.  Turn ignition switch OFF and cool the engine.
2.  Turn ignition switch ON.

   CAUTION: Never start the engine.

3.  Select "Data Monitor" in "TRANSMISSION".
4.  Select "FLUID TEMP".
5.  Record CVT fluid temperature.
6.  Start the engine and wait for at least 2 minutes.
7.  Drive the vehicle for the total minutes specified in the Driving time column below with the following conditions satisfied.

8. Stop the vehicle.

9. Check the first trip DTC.

With GST

1.  Turn ignition switch OFF and cool the engine.
2.  Start the engine and wait for at least 2 minutes.
3.  Drive the vehicle and maintain the following conditions for 17 minutes or more.
4.  Stop the vehicle.
5.  Check the first trip DTC.

3.CHECK CVT FLUID TEMPERATURE SENSOR

1.  Turn ignition switch OFF.
2.  Disconnect CVT unit connector.
3.  Check resistance between CVT unit connector terminals.

Diagnosis Procedure

Regarding Wiring Diagram information, refer to TM-126, "Wiring Diagram".

1.CHECK CVT FLUID TEMPERATURE SENSOR CIRCUIT

1.  Turn ignition switch OFF.
2.  Disconnect TCM connector.
3.  Check resistance between TCM vehicle side harness connector terminals.

2.CHECK HARNESS BETWEEN TCM AND CVT UNIT (CVT TEMPERATURE SENSOR) (PART 1)

1.  Disconnect CVT unit connector.
2.  Check continuity between TCM vehicle side harness connector terminals and CVT unit vehicle side harness connector terminals.

3.CHECK HARNESS BETWEEN TCM AND CVT UNIT (CVT TEMPERATURE SENSOR) (PART 2)

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

4.CHECK CVT FLUID TEMPERATURE SENSOR

Check CVT fluid temperature sensor. Refer to TM-56, "Component Inspection (CVT Fluid Temperature Sensor)".

5.DETECT MALFUNCTIONING ITEMS

Check TCM connector pin terminals for damage or loose connection with harness connector.
