DTC Troubleshooting: P0983 (60)

DTC P0983:

Open in Shift Solenoid Valve D Circuit

NOTE:

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

2. Clear the DTC with the HDS.

3. Start the engine with the shift lever in P, and wait for at least 1 second.

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

Is DTC P0983 indicated?

YES -

Go to step 8.

NO -

Go to step 5.

5. 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 6.

NO -

Go to step 8.

6. Start the engine with the shift lever in P, and wait for at least 1 second.

7. Monitor the OBD STATUS for P0983 in the DTCs MENU with the HDS.

Does the HDS indicate FAILED?

YES -

Go to step 8.

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 5.

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

9. Jump the SCS line with the HDS.

10. Disconnect PCM connector A (49P).

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

12. Measure the voltage between PCM connector terminal A1 and body ground.





Is there battery voltage?

YES -

Go to step 13.

NO -

Check for a blown No. 10 (10 A) fuse in the driver's under-dash fuse/relay box. If the fuse is blown, replace it. If the fuse blows again, repair a short in the No. 10 (10 A) fuse circuit. If the fuse is OK, repair an open in the wire between PCM connector terminal A1 and the driver's under-dash fuse/relay box, then go to step 21.

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

14. Jump the SCS line with the HDS.

15. Disconnect PCM connector B (49P).

16. Measure the resistance between PCM connector terminal B27 and body ground.





Is there 12-25 Ohms?

YES -

Go to step 27.

NO -

Go to step 17.

17. Disconnect the shift solenoid wire harness connector.

18. Check for continuity between PCM connector terminal B27 and shift solenoid wire harness connector terminal No. 8.





Is there continuity?

YES -

Go to step 19.

NO -

Repair an open in the wire between PCM connector terminal B27 and shift solenoid wire harness connector terminal No. 8, then go to step 21.

19. Remove the shift solenoid wire harness Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement (A/T).

20. Check for continuity between shift solenoid wire harness connector terminal No. 8 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 (A/T), then go to step 24.

NO -

Replace the shift solenoid wire harness Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement (A/T), then go to step 24.

21. Reconnect all connectors.

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

23. Clear the DTC with the HDS.

24. Start the engine with the shift lever in P, and wait for at least 1 second. Then test-drive the vehicle in 2nd gear with the shift lever in D for at least 1 second.

25. 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 26.

26. 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 25, 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 24.

27. Reconnect all connectors.

28. Update the PCM if it does not have the latest software ECM/PCM Update (M/T), or substitute a known-good PCM.

29. Start the engine with the shift lever in P, and wait for at least 1 second. Then test-drive the vehicle in 2nd gear with the shift lever in D for at least 1 second.

30. 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. If the PCM was updated, substitute a known-good PCM, then go to step 29. If the PCM was substituted, go to step 1.

NO -

Go to step 31.

31. 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 30, 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 29. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 29.
