DTC Confirmation Procedure

WARNING:

If you do not select a suitable route and take proper precautions when performing a road test, an accident can occur.

- Select a level road with no traffic to minimize the risk of accident.
- Perform the test extremely carefully.
- Perform the road test using 2 persons, a driver and an assistant.

NOTE:

- If other DTC than P0711 is newly detected during this "DTC Confirmation Procedure", troubleshoot the newly detected DTC in first.
- Confirm that the following conditions are met in this procedure.

- Battery voltage > 10.5 V

1) Drive vehicle at more than 50 km/h (31 mile/h) for 7 min.
2) Stop vehicle.
3) Push engine switch to change ignition mode to "OFF", and leave ignition mode in "OFF" for 10 sec.
4) Push engine switch to change ignition mode to "ON".
5) Repeat Step 1) through 2) twice.

DTC Troubleshooting

1.
Was "CVT System Check" performed?
YES -
Go to Step 2.
NO -
Go to CVT System Check CVT System Check.

2. CVT fluid temperature sensor signal circuit check

Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect "C142", "E19" and "E20" connectors.
Check for proper terminal connection to "C142", "E19" and "E20" connectors.
If connections are OK, check the following points.
- Resistance of "A1" and "A2" circuits: less than 1 ohms
- Resistance of "A1" circuit between "C142" connector and ground: infinity
- Resistance between "A1" circuit terminal and each terminal at "C142" connector: infinity
- Voltage of "A1" and "A2" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON")

Are they in good condition?
YES -
Go to Step 3.
NO -
Repair or replace defective wire harness.

3. CVT fluid temperature sensor check

Check CVT fluid temperature sensor. Testing and Inspection

Are they in good condition?
YES -
Go to Step 4.
NO -
Replace CVT fluid temperature sensor (valve body assembly). Service and Repair

4. DTC recheck

Clear DTC. DTC Clearance
Confirm that ignition mode of keyless push start system is in "OFF".
Perform DTC confirmation procedure, and check DTC.

Is DTC P0711 still detected?
YES -
Go to Step 5.
NO -
Substitute a known-good TCM and recheck DTC. Service and Repair

5. ECT sensor check

Check ECT sensor. ECT Sensor Inspection

Is it in good condition?
YES -
Replace ECM and recheck DTC. Service and Repair
NO -
Replace ECT sensor. ECT Sensor Removal and Installation
