DTC P0963: Problem in A/T Clutch Pressure Control Solenoid Valve ANOTE:
^ Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information.
^ This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
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 Control in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve A with the HDS.
Does the screen indicate NORMAL?
YES - Go to step 6.
NO - Go to step 8.
6. Command A/T clutch pressure control solenoid valve A at 0.2 A in Clutch Pressure Control Solenoid Control menu.
7. Monitor the OBD STATUS for P0963 in the DTCs MENU with the HDS.
Does the screen indicate FAILED?
YES - Go to step 8.
NO - If the screen 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 screen 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.
Is there 3 - 10 ohms ?
YES - Go to step 11.
NO - Replace A/T clutch pressure control solenoid valve A, then go to step 12.
11. Check for continuity between A/T clutch pressure control solenoid valve A connector terminal No. 2 and body ground.
Is there continuity?
YES - Go to step 18.
NO - Repair open in the wire between A/T clutch pressure control solenoid valve A and ground (G101), or repair poor ground (G101), then go to step 12.
12. Reconnect all connectors.
13. Turn the ignition switch to ON (II).
14. Clear the DTC with the HDS.
15. Start the engine, and wait for at least 1 second.
16. Check for DTCs with the HDS.
Is DTC P0963 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 17.
17. Monitor the OBD STATUS for P0963 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - Troubleshooting is complete. If any other DTCs were indicated in step 16, go to the indicated DTC's troubleshooting.
NO - If the screen 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 screen indicates NOT COMPLETED, go to step 15.
18. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
19. Start the engine, and wait for at least 1 second.
20. Check for DTCs with the HDS.
Is DTC P0963 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, then go to step 19. If the PCM was substituted, go to step 1.
NO - Go to step 21.
21. Monitor the OBD STATUS for P0963 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. If any other DTCs were indicated in step 20, go to the indicated DTC's troubleshooting.
NO - If the screen 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, then go to step 19. If the PCM was substituted, go to step 1. If the screen indicates NOT COMPLETED, go to step 19.
