DTC Troubleshooting
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. Clear the DTC with the HDS.
2. Test-drive the vehicle for several minutes in the D position through all five gears.
3. Check that DTC P0963 recurs.
Is DTC P0963 indicated?
YES - Go to step 7.
NO - Go to step 4.
4. Choose CLUTCH PRESSURE CONTROL SOLENOID A in 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 5.
NO - Go to step 7.
5. Command A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE A at 0.2 A in CLUTCH PRESSURE CONTROL SOLENOID CONTROL MENU with the HDS.
6. Monitor the OBD STATUS for P0963 in the DTCs MENU with the HDS.
Does the screen indicate FAILED?
YES - Go to step 7.
NO - If the screen indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at A/T clutch pressure control solenoid valve A and the PCM. If the HDS indicates NOT COMPLETED, return to step 4 and recheck.
7. Turn the ignition switch OFF.
8. Disconnect the A/T clutch pressure control solenoid valve A connector.
9. Measure 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 10.
NO - Replace A/T clutch pressure control solenoid valve A, then go to step 12.
10. 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 17.
NO - Repair open in the wire between A/T clutch pressure control solenoid valve A and ground (G101, G102), or repair poor ground (G101, G102), then go to step 11.
11. Reconnect all connectors.
12. Turn the ignition switch ON (II).
13. Clear the DTC with HDS.
14. Test-drive the vehicle for several minutes in the D position through all five gears.
15. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0963 indicated?
YES - Check for poor connections or loose terminals at A/T clutch pressure control solenoid valve A and the PCM, then go to step 1.
NO - Go to step 16.
16. Monitor the OBD STATUS for P0963 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - Troubleshooting is complete.
NO - Return to step 7 and recheck.
17. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
18. Test-drive the vehicle for several minutes in the D position through all five gears.
19. Check for Temporary DTCs or DTCs with the HDS. Is DTC P0963 indicated?
YES - Check for poor connections or loose terminals at 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 18. If the PCM was substituted, go to step 1.
NO - Go to step 20.
20. Monitor the OBD STATUS for P0963 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - Troubleshooting is complete.
NO - Return to step 7 and recheck.
