^ Record all freeze data and review the General Troubleshooting Information before you troubleshoot.
^ 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. Check that DTC P0963 recurs.
Is DTC P0963 indicated?
YES-Go to step 6.
NO-Go to step 3.
3. Choose Clutch Pressure Control Solenoid Control in Miscellaneous Test Menu, and test the A/T clutch pressure control solenoid valve A with the HDS.
4. Drive with the A/T clutch pressure control solenoid valve A at 0.2 A in Clutch Pressure Control Solenoid Control menu.
5. Check the OBD status in DTC Monitor Tool from DTCs/Freeze Data in A/T Mode Menu for a pass/fail test of code P0963.
Did the result indicate a fail?
YES-Go to step 6.
NO-Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETE, return to step 3 and recheck.
6. Turn the ignition switch OFF.
7. Disconnect the A/T clutch pressure control solenoid valve A connector.
8. Measure A/T clutch pressure control solenoid valve A resistance at the solenoid connector.
Terminal side of male terminals
Is there less than 3 Ohms?
YES-Go to step 9.
NO-Replace the A/T clutch pressure control solenoid valve A, then go to step 12.
9. Jump the SCS line with the HDS.
10. Disconnect PCM connectors B (44P) and C (44P).
11. Check for continuity between PCM connector terminals B1 and body ground, between B36 and body ground, between B43 and body ground, and between C40 and body ground.
Is there continuity?
YES--Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
NO-Repair open in the wires between PCM connector terminals B1, B36, B43, C40, and ground (G101), or repair poor ground (G101), then go to step 12.
12. Clear the DTC with the HDS.
13. Test-drive the vehicle for several minutes in the D position in all five gears.
14. Check the OBD status in DTC Monitor Tool from DTCs/Freeze Data in A/T Mode Menu for a pass/fail test of code P0963.
Did the result indicate a pass?
YES-The problem has been corrected.
NO-Return to step 1 and recheck.
