NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-3).
1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Make sure that the transmission is filled to the proper level, and check for fluid leaks.
3. Drain the ATF (see step 3 on page 14-232) through a strainer. Inspect the strainer for metal debris or
excessive clutch material.
Replace the transmission, then go to step 13.
Replace the ATF (see page 14-232), then go to
step 4.
4. Turn the ignition switch to ON (II).
5. Clear the DTC with the HDS.
6. Select Shift Solenoid Valve E in the Miscellaneous Test Menu, and check that shift solenoid valve E
operates with the HDS.
Go to step 7.
Replace shift solenoid valve E (see page
14-217), then go to step 11.
7. Run the engine until the ECT Sensor temperature reaches 80 °C (176 °F).
8. Select Clutch Pressure Control (Linear) Solenoid Valve A in the Miscellaneous Test Menu, and test
A/T clutch pressure control solenoid valve A with
the HDS.
Go to step 9.
Follow the instructions indicated on the HDS
accordingtothetestresult.Gotostep11ifanypart
was replaced. 9. Test-drive the vehicle on a level road with a steady
speed at 96 km/h (60 mph) for at least 20 seconds.
10. Monitor the OBD STATUS for P0741 in the DTCs MENU with the HDS.
Repair the faulty torque converter clutch
mechanism, the torque converter clutch hydraulic
circuit, the lock-up shift valve, or the lock-up control
valve, or replace the transmission, then go to step
13.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. If the HDS
indicates NOT COMPLETED, go to step 9.
11. Turn the ignition switch to ON (II).
12. Clear the DTC with the HDS.
13. Test-drive the vehicle on a level road with a steady speed at 96 km/h (60 mph) for at least 20 seconds,
or test-drive the vehicle for several minutes under
the same condition as those indicated by the freeze
data.
14. Check for Temporary DTCs or DTCs with the HDS.
Go to step 5.
Go to step 15.
15. Monitor the OBD STATUS for P0741 in the DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 14,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, go to step 5. If
the HDS indicates NOT COMPLETED, go to step 13.
