DTC P0962: Problem in A/T Clutch Pressure Control Solenoid Valve A CircuitNOTE:
^ 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 ON (II).
2. Clear the DTC with the HDS.
3. Start the engine, and wait far at least 1 second.
4. Check for DTCs with the HDS.
Is DTC P0962 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.
Is the result NORMAL?
YES - Go to step 6.
NO - Go to step 8.
6. Command A/T clutch pressure control solenoid valve A at 1.0 A in Clutch Pressure Control Solenoid Control menu.
7. Monitor the OBD STATUS for P0962 in the DTCs MENU with the HDS.
Does the screen indicate FAILED?
YES - Go to step 5.
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 4.
8. Turn the ignition switch OFF.
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 19.
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 12.
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 19.
12. Turn the ignition switch ON (II).
13. Measure the voltage between A/T clutch pressure control solenoid valve A connector terminals No. 1 and No. 2.
Is there battery voltage?
YES - Go to step 14.
NO - Repair open or short in the wire between PCM connector terminal C19 and A/T clutch pressure control solenoid valve A, then go to step 19.
14. Turn the ignition switch OFF.
15. Jump the SCS line with the HDS.
16. Disconnect PCM connectors B (44P) and C (44P).
17. Turn the ignition switch ON (II).
18. Measure the voltage between PCM connector terminals B2 and C40.
Is there battery voltage?
YES - Go to step 25.
NO - Check for a blown No. 6 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 B2 and the driver's under-dash fuse/relay box, then go to step 19.
19. Reconnect all connectors.
20. Turn the ignition switch ON (II).
21. Clear the DTC with the HDS.
22. Start the engine, and wait for at least 1 second.
23. 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, 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 screen indicate PASSED?
YES - Troubleshooting is complete. If any other DTCs were indicated in step 23, 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 22.
25. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
26. Start the engine, and wait for at least 1 second.
27. 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, then go to step 26. If the PCM was substituted, go to step 1.
NO - Go to step 28.
28. Monitor the OBD STATUS for P0962 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 27, 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 26. If the PCM was substituted, go to step 1. If the screen indicates NOT COMPLETED, go to step 26.
