DTC Troubleshooting: P0983 (60)
DTC P0983:
Shift Solenoid Valve D (Open)
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information How to Troubleshoot the A/T System.
- 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. Start the engine in P. With the brake pedal pressed, shift to N, and wait for at least 1 second.
3. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0983 indicated?
YES -
Go to step 7.
NO -
Go to step 4.
4. Select Shift Solenoid Valve D in the Miscellaneous Test Menu, and test shift solenoid valve D with the HDS.
Is a clicking sound heard?
YES -
Go to step 5.
NO -
Go to step 7.
5. Start the engine in P. With the brake pedal pressed, shift to N, and wait for at least 1 second.
6. Monitor the OBD STATUS for P0983 in the DTCs MENU with the HDS.
Does the HDS indicate FAILED?
YES -
Go to step 7.
NO -
If the HDS indicates PASSED, 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 HDS indicates NOT COMPLETED, go to step 4.
7. Turn the ignition switch to LOCK (0).
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector B (44P).
10. Measure the resistance between PCM connector terminal B24 and body ground.
Is there 12-25 Ohms?
YES -
Connect PCM connector B (44P), then go to step 15.
NO -
Go to step 11.
11. Disconnect the shift solenoid wire harness connector.
12. Check for continuity between PCM connector terminal B24 and shift solenoid wire harness connector terminal No. 1.
Is there continuity?
YES -
Go to step 13.
NO -
Repair an open in the wire between PCM connector terminal B24 and the shift solenoid wire harness connector, then go to step 19.
13. Remove the shift solenoid wire harness Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement.
14. Check for continuity between shift solenoid wire harness connector terminal No. 1 and the shift solenoid valve D connector terminal.
Is there continuity?
YES -
Replace shift solenoid valve D Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement, then go to step 19.
NO -
Replace the shift solenoid wire harness Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement, then go to step 19.
15. Update the A/T software in the PCM if it does not have the latest software PCM Update, or substitute a known-good PCM.
16. Start the engine in P and wait for at least 1 second. With the brake pedal pressed, shift to N, and wait for at least 1 second.
17. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0983 indicated?
YES -
If the PCM was updated, substitute a known-good PCM, then go to step 16. If the PCM was substituted, go to step 1.
NO -
Go to step 18.
18. Monitor the OBD STATUS for P0983 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 in step 17, go to the indicated DTC's troubleshooting.
NO -
If the HDS 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 16. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 16.
19. Reconnect all connectors.
20. Clear the DTC with the HDS.
21. Start the engine in P and wait for at least 1 second. With the brake pedal pressed, shift to N, and wait for at least 1 second.
22. Check for Pending or Confirmed 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 23.
23. Monitor the OBD STATUS for P0983 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 in step 22, go to the indicated DTC's troubleshooting.
NO -
If the HDS indicates FAILED, check for poor connections or loose terminals between shift solenoid valve D and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 21.
