17. Reconnect all connectors.

18. Turn the ignition switch to ON (II).

19. Clear the DTC with the HDS.

20. Start the engine in P, and wait for at least 1 second.

21. Test-drive the vehicle in 1st gear in D for at least

1 second.

22. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals at shift solenoid valve C, the shift
solenoid harness, and the PCM, then go to step 1.

If Temporary DTC or DTC P0980 is not

indicated, or if any other Temporary DTCs are
indicated, go to step 23.

23. Monitor the OBD STATUS for P0980 in the DTCs

MENU with the HDS.

Troubleshooting is complete. If any other

Temporary DTC or DTCs were indicated on step 22,
go to the indicated DTCs troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at shift solenoid
valve C, the shift solenoid harness, and the PCM,
then go to step 1. If the screen indicates NOT
COMPLETED, go to step 20.

24. Update the PCM if it does not have the latest

software (see page 14-8), or substitute a known-
good PCM (see page 14-9).

25. Start the engine in P, and wait for at least 1 second.

26. Test-drive the vehicle in 1st gear in D for at least

1 second.

27. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals at shift solenoid valve C, the shift
solenoid harness, and the PCM. If the PCM was
updated, substitute a known-good PCM (see page
14-9), then go to step 25. If the PCM was substituted,
go to step 1.

If Temporary DTC or DTC P0980 is not

indicated, or if any other Temporary DTCs or DTCs
are indicated, go to step 28.

28. Monitor the OBD STATUS for P0980 in the DTCs

MENU with the HDS.

If the PCM was updated, troubleshooting is

complete. If the PCM was substitute, replace the
original PCM (see page 11-205). If any other
Temporary DTCs or DTCs were indicated on step
27, go to the indicated DTCs troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at shift solenoid
valve C, the shift solenoid harness, and the PCM. If
the PCM was updated, substitute a known-good
PCM (see page 14-9), then go to step 25. If the PCM
was substituted, go to step 1. If the screen indicates
NOT COMPLETED, go to step 25.

NOTE:

• Before you troubleshoot, record all freeze data and

any on-board snapshot, and review General
Troubleshooting Information (see page 14-4).

• This code is caused by an electrical circuit problem

and cannot be caused by a mechanical problem in the
transmission.

1. Clear the DTC with the HDS.

2. Start the engine in P, and warm it up to normal

operating temperature (the radiator fan comes on).
Test-drive the vehicle at a constant speed of
37 mph (60 km/h) in D, in 5th gear for at least
1 second.

3. Check that DTC P2769 recurs.

Go to step 7.

Go to step 4.

4. Select LOCKUP SOLENOID TEST in

MISCELLANEOUS TEST MENU, and test TORQUE
CONVERTER CLUTCH SOLENOID VALVE with the
HDS.

Go to step 5.

Go to step 7.

5. Start the engine in P, and warm it up to normal

operating temperature (the radiator fan comes on).
Test-drive the vehicle at a constant speed of
37 mph (60 km/h) in D, in 5th gear for at least
1 second.

6. Monitor the OBD STATUS for P2769 in the DTCs

MENU with the HDS.

Intermittent failure, the system is OK at this

time. Check LC (YEL) wire for an intermittent short
to ground between torque converter clutch
solenoid valve and the PCM.

If the screen indicates FAILED, go to step 7. If

the screen indicates NOT COMPLETED, return to
step 4 and recheck.

7. Turn the ignition switch to LOCK (0).

8. Jump the SCS line with the HDS.

9. Disconnect PCM connectors B (44P) and C (44P).

10. Measure the resistance between PCM connector

terminals B44 and B43 or C40.

Go to step 11.

Go to step 21.

11. Disconnect the shift solenoid harness connector.

12. Check for continuity between PCM connector

terminals B44 and B43 or C40.

Repair a short to ground in the wire between

PCM connector terminal B44 and the shift solenoid
harness connector, then go to step 15.

Go to step 13.

13. Inspect the torque converter clutch solenoid valve

and the shift solenoid harness (see page 14-188).

Go to step 21.

Go to step 14.

14. Replace the torque converter clutch solenoid valve

or the shift solenoid harness (see page 14-188).

15. Reconnect all connectors.

16. Turn the ignition switch to ON (II).

17. Clear the DTC with the HDS.

18. Start the engine in P, and warm it up to normal

operating temperature (the radiator fan comes on).
Test-drive the vehicle at a constant speed of
37 mph (60 km/h) in D, in 5th gear for at least
1 second.

19. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals at the torque converter clutch solenoid
valve, the shift solenoid harness, and the PCM,
then go to step 1.

If Temporary DTC or DTC P2769 is not

indicated, or if any other Temporary DTCs are
indicated, go to step 20.

20. Monitor the OBD STATUS for P2769 in the DTCs

MENU with the HDS.

Troubleshooting is complete. If any other

Temporary DTC or DTCs were indicated on step 19,
go to the indicated DTCs troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at the torque
converter clutch solenoid valve, the shift solenoid
harness, and the PCM, then go to step 1. If the
screen indicates NOT COMPLETED, go to step 18.
