DTC Troubleshooting
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. Clear the DTC with the HDS.
2. Check that DTC P0962 recurs.
Is DTC P0962 indicated?
YES - Go to step 6.
NO - Go to step 3.
3. Choose Clutch Pressure Control (Linear) Solenoid A 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 4.
NO - Go to step 6.
4. Choose Clutch Pressure Control Solenoid Control in the Miscellaneous Test Menu, and command A/T clutch pressure control solenoid valve A at 1.0 A with the HDS.
5. Monitor the OBD STATUS for P0962 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to step 6.
NO - Intermittent failure, the system is OK at this time. Check for poor connections and 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 OFF.
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 then go to step 24.
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 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 24.
10. Turn the ignition switch ON (II).
11. Measure the voltage between A/T clutch pressure control solenoid valve A connector terminals No. 1 and No. 2.
Is there momentarily battery voltage, when the ignition switch is turned ON (II)?
YES - Go to step 19.
NO - Check for open or short in the wire between PCM connector terminal C21 and A/T clutch pressure control solenoid valve A, if the wiring is OK, go to step 12.
12. Turn the ignition switch OFF.
13. Jump the SCS line with the HDS.
14. Disconnect PCM connectors B (49P) and C (49P).
15. Turn the ignition switch ON (II).
16. Measure the voltage between PCM connector terminals B2 and B41 or C41.
Is there battery voltage?
YES - Go to step 19.
NO - Go to step 17.
17. Turn the ignition switch OFF.
18. Check for continuity between PCM connector terminals B41 and body ground, and between C41 and body ground.
Is there continuity?
YES - Check for a blown No. 18 fuse in the under-dash fuse/relay box. If the fuse is OK, repair open in the wire between PCM connector terminal B2 and the under-dash fuse/relay box, then go to step 24.
NO - Repair open in the wires between PCM connector terminals B41, C41 and ground (G101) or repair poor ground (G101) then go to step 24.
19. Reconnect all connectors.
20. Update the A/T software in the PCM if it does not have the latest software or substitute a known-good PCM.
21. Test-drive the vehicle for several minutes in the D position through all five gears.
22. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.
Is DTC P0962 indicated?
YES - If the PCM was updated, substitute a known-good PCM then recheck. If the PCM was substituted, go to step 1.
NO - Go to step 23.
23. Monitor the OBD STATUS for P0962 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result 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 on step 22, go to the indicated DTC's troubleshooting.
NO - If the HDS indicates FAILED, 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 then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 21 and recheck.
24. Clear the DTC with the HDS.
25. Test-drive the vehicle for several minutes in the D position through all five gears.
26. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu 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 27.
27. Monitor the OBD STATUS for P0962 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate PASSED?
YES - Troubleshooting is complete. If any other DTCs were indicated on step 26, go to the indicated DTC's troubleshooting.
NO - If the HDS indicates FAILED, 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 25 and recheck.
