valve A connector terminal No. 1 and PCM connector terminal B35, then go to
step 16.

16. Reconnect all connectors.
17. Turn the ignition switch to ON (II).
18. Clear the DTC with the HDS.
19. Start the engine, and wait for at least 1 second.

Is DTC P0962 indicated?

YES -Check for poor connections or loose terminals between A/T clutch
pressure control solenoid valve A and the PCM, then go to step 1.

NO -Go to step 21.

21. Monitor the OBD STATUS for P0962 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES -Troubleshooting is complete. If any other DTCs were indicated in step
20, go to the INDICATED DTC'S TROUBLESHOOTING.

NO -If the HDS indicates FAILED, check for poor connections or loose
terminals between A/T clutch pressure control solenoid valve A and the PCM,
then go to step 1. If the HDS indicates NOT COMPLETED, go to step 19.

22. Update the PCM if it does not have the latest software (see UPDATING THE

PCM ), or substitute a known-good PCM (see SUBSTITUTING THE
PCM ).

23. Start the engine, and wait for at least 1 second.
24. Check for DTCs with the HDS.

Is DTC P0962 indicated?

YES -Check for poor connections or loose terminals between A/T clutch
pressure control solenoid valve A and the PCM. If the PCM was updated,
substitute a known-good PCM (see SUBSTITUTING THE PCM ), then go to
step 23. If the PCM was substituted, go to step 1.

NO -Go to step 25.

25. Monitor the OBD STATUS for P0962 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES -If the PCM was updated, troubleshooting is complete. If the PCM was

substituted, replace the original PCM (see ECM/PCM REPLACEMENT ). If
any other DTCs were indicated in step 24, go to the INDICATED DTC'S
TROUBLESHOOTING.

NO -If the HDS indicates FAILED, check for poor connections or loose
terminals between A/T clutch pressure control solenoid valve A and the PCM.
If the PCM was updated, substitute a known-good PCM (see
SUBSTITUTING THE PCM ), then go to step 23. If the PCM was
substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step
23.

DTC P0963: Problem in A/T Clutch Pressure Control Solenoid Valve A

1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine, and wait for at least 1 second.
4. Check for DTCs with the HDS.

Is DTC P0963 indicated?

YES -Go to step 8.

NO -Go to step 5.

5. Select Clutch Pressure Control Solenoid Valve A in the Miscellaneous Test

Menu, and test A/T clutch pressure control solenoid valve A with the HDS.

Does the HDS indicate NORMAL?

NOTE:

Before you troubleshoot, record all freeze data and any
on-board snapshot with the HDS, and review General
Troubleshooting Information (see GENERAL
TROUBLESHOOTING INFORMATION ).

This code is caused by an electrical circuit problem and
cannot be caused by a mechanical problem in the
transmission.

YES -Go to step 6.

NO -Go to step 8.

6. In the Clutch Pressure Control Solenoid Valve Control menu, select A/T clutch

pressure control solenoid valve A at 0.2 A.

7. Monitor the OBD STATUS for P0963 in the DTCs MENU with the HDS.

Does the HDS indicate FAILED?

YES -Go to step 8.

NO -If the HDS indicates PASSED, intermittent failure, the system is OK at
this time. Check for poor connections or loose terminals between A/T clutch
pressure control solenoid valve A and the PCM. If the HDS indicates NOT
COMPLETED, go to step 5.

8. Turn the ignition switch to LOCK (0).
9. Disconnect the A/T clutch pressure control solenoid valve A connector.

10. Measure the resistance between A/T clutch pressure control solenoid valve A

connector terminals No. 1 and No. 2.
