DTC Troubleshooting
DTC P0983: Open in Shift Solenoid Valve D 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. Test-drive the vehicle for several minutes in the D position through all five gears.
4. Check for DTCs with the HDS.
Is DTC P0983 indicated?
YES - Go to step 8.
NO - Go to step 5.
5. Choose Shift Solenoid D in Miscellaneous Test Menu, and test shift solenoid valve D with the HDS.
Is a clicking sound heard?
YES - Go to step 6.
NO - Go to step 8.
6. Test-drive the vehicle for several minutes in the D position through all five gears.
7. Monitor the OBD STATUS for P0983 in the DTCs MENU with the HDS.
Does the screen indicate FAILED?
YES - Go to step 8.
NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between shift solenoid valve D and the PCM. If the screen indicates NOT COMPLETED, go to step 5.
8. Turn the ignition switch OFF.
9. Jump the SCS line with the HDS.
10. Disconnect PCM connectors A (31P) and C (22P).
11. Measure the resistance between PCM connector terminals C2 and A3.
Is there 12-25 Ohms?
YES - Go to step 22.
NO - Go to step 12.
12. Disconnect the shift solenoid harness connector at the transmission housing.
13. Check for continuity between PCM connector terminal C2 and shift solenoid harness connector terminal No. 1.
Is there continuity?
YES -Go to step 14.
NO - Repair open in the wire between PCM connector terminal C2 and the shift solenoid harness connector, then go to step 16.
14. Remove the shift solenoid harness.
15. Check for continuity between shift solenoid harness connector terminal No. 1 and the shift solenoid valve D connector terminal.
Is there continuity?
YES - Replace shift solenoid valve D, then go to step 16.
NO - Replace the shift solenoid harness, then go to step 16.
16. Reconnect all connectors.
17. Turn the ignition switch ON (II).
18. Clear the DTC with the HDS.
19. Test-drive the vehicle for several minutes in the D position through all five gears.
20. Check for DTCs with the HDS.
Is DTC P0983 indicated?
YES - Check for poor connections or loose terminals between shift solenoid valve D and the PCM, then go to step 1.
NO - Go to step 21.
21. Monitor the OBD STATUS for P0983 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - Troubleshooting is complete. If any other DTCs were indicated in step 20, go to the indicated DTC's troubleshooting.
NO - If the screen indicates FAILED, check for poor connections or loose terminals between shift solenoid valve D and the PCM, then go to step 1. If the screen indicates NOT COMPLETED, go to step 19.
22. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
23. Test-drive the vehicle for several minutes in the D position through all five gears.
24. Check for DTCs with the HDS.
Is DTC P0983 indicated?
YES - Check for poor connections or loose terminals between shift solenoid valve D and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 23. If the PCM was substituted, go to step 1.
NO - Go to step 25.
25. Monitor the OBD STATUS for P0983 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 24, go to the indicated DTC's troubleshooting.
NO - If the screen indicates FAILED, check for poor connections or loose terminals between shift solenoid valve D and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 23. If the PCM was substituted, go to step 1. If the screen indicates NOT COMPLETED, go to step 23.
