DTC Troubleshooting: P0962

DTC P0962: A/T Clutch Pressure Control Solenoid Valve A (Open)

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information. How To Troubleshoot A/T Systems

- 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 if DTC P0962 records.

Is DTC P0962 indicated?
YES - Go to step 6.

NO - Go to step 3.


3. Select Clutch Pressure Control (Linear) Solenoid A in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve A with the HDS.

Does the HDS indicate NORMAL?
YES - Go to step 4.

NO - Go to step 6.


4. In the Clutch Pressure Control Solenoid Valve Control menu, select A/T Clutch Pressure Control Solenoid Valve A at 1.0 A.

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

Does the HDS indicate FAILED?
YES - Go to step 6.

NO - 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 3 and recheck.


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

7. Disconnect the A/T clutch pressure control solenoid valve A connector.

8. 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 9.

NO - Replace A/T clutch pressure control solenoid valve A, A/T Clutch Pressure Control Solenoid Valve A and B Replacement then go to step 21.






9. 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 10.

NO - Repair an 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 21.






10. Jump the SCS line with the HDS.

11. Disconnect PCM connector C (22P).

12. Check for continuity between PCM connector terminal C7 and A/T clutch pressure control solenoid valve A connector terminal No. 1.

Is there continuity?
YES - Go to step 13.

NO - Repair an open in the wire between PCM connector terminal C7 and A/T clutch pressure control solenoid valve A, then go to step 21.






13. Check for continuity between A/T clutch pressure control solenoid valve A connector terminal No. 1 and body ground.

Is there continuity?
YES - Repair a short in the wire between PCM connector terminal C7 and A/T clutch pressure control solenoid valve A, then go to step 21.

NO - Go to step 14.






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

15. Measure the voltage between PCM connector terminal A10 and body ground.

Is there battery voltage?
YES - Turn the ignition switch to LOCK (0), then go to step 16.

NO - Check for blown No. 18 fuse in the driver's under-dash fuse/relay box. If the fuse is OK, repair an open in the wire between PCM connector terminal A10 and the driver's under-dash fuse/relay box, then go to step 21.






16. Reconnect all connectors.

17. Update the A/T software in the PCM if it does not have the latest software, PCM Update or substitute a known-good PCM. Reading and Clearing Diagnostic Trouble Codes

18. Start the engine, and wait for at least 1 second.

19. Check for Pending or Confirmed DTCs with the HDS.

Is DTC P0962 indicated?
YES - If the PCM was updated, substitute a known-good PCM, Reading and Clearing Diagnostic Trouble Codes then recheck. If the PCM was substituted, go to step 1.

NO - Go to step 20.


20. 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. Service and Repair If any other Pending or Confirmed DTCs were indicated on step 19, go to the indicated DTC's troubleshooting.

NO - Check for poor connections and loose terminals at A/T clutch pressure control solenoid valve A and the PCM. If the PCM was updated, substitute a known-good PCM, Reading and Clearing Diagnostic Trouble Codes then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 18 and recheck.


21. Clear the DTC with the HDS.

22. Start the engine, and wait for at least 1 second.

23. Check for Pending or Confirmed DTCs with the HDS.

Is DTC P0962 indicated?
YES - Check for poor connections and loose terminals at A/T clutch pressure control solenoid valve A and the PCM, then go to step 1.

NO - Go to step 24.


24. 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 Pending or Confirmed DTCs were indicated on step 23, go to the indicated DTC's troubleshooting.

NO - Check for poor connections and loose terminals at A/T clutch pressure control solenoid valve A and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 22 and recheck.
