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. Clear the DTC with the HDS.
2. Start the engine in P. Wait at least 1 second.
3. Check that DTC P0983 recurs.
Is DTC P0983 indicated?
Yes - Go to step 7.
No - Go to step 4.
4. Select Shift Solenoid 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. Wait at least 1 second.
6. Monitor the OBD STATUS for P0983 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate FAILED?
Yes - Go to step 7.
No - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at shift solenoid valve D and the PCM. If the HDS indicates NOT COMPLETED, return to step 4 and recheck.
7. Turn the ignition switch to LOCK (0).
8. Jump the SCS line with the HDS.
9. Disconnect PCM connectors B (44P) and C (44P).
10. Measure the resistance between PCM connector terminals B26 and C40.
Is there 12-25 Ohms?
Yes - Go to step 15.
No - Go to step 11.
11. Disconnect the shift solenoid harness connector.
12. Check for continuity between PCM connector terminal B26 and shift solenoid harness connector terminal No. 8.
Is there continuity?
Yes - Go to step 13.
No - Repair open in the wire between PCM connector terminal B26 and the shift solenoid harness connector, then go to step 20.
13. Remove the shift solenoid harness.
14. Check for continuity between shift solenoid harness connector terminal No. 8 and the shift solenoid valve D connector terminal.
Is there continuity?
Yes - Replace shift solenoid valve D, then go to step 20.
No - Replace the shift solenoid harness, then go to step 20.
15. Connect PCM connectors B (44P) and C (44P).
16. Update the A/T software in the PCM if it does not have the latest software, or substitute a known-good PCM.
17. Turn the ignition switch to ON (II), and wait for at least 1 second. Test-drive the vehicle in 2nd gear in D for at least 1 second, then slow down to a stop.
18. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.
Is DTC P0983 indicated?
Yes - If the PCM was updated, substitute a known-good PCM, then recheck. If the PCM was substituted, reinstall the original PCM, then go to step 1.
No - Go to step 19.
19. Monitor the OBD STATUS for P0983 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS 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 18, go to the indicated DTC's troubleshooting.
No - Check for poor connections and loose terminals at shift solenoid valve D and the PCM. If the PCM was updated, substitute a known-good PCM, then recheck. If the PCM was substituted, reinstall the original PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 17 and recheck.
20. Reconnect all connectors.
21. Clear the DTC with the HDS.
22. Turn the ignition switch to ON (II), and wait for at least 1 second. Test-drive the vehicle in 2nd gear in D for at least 1 second, then slow down to a stop.
23. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.
Is DTC P0983 indicated?
Yes - Check for poor connections and loose terminals at shift solenoid valve D and the PCM, then go to step 1.
No - Go to step 24.
24. Monitor the OBD STATUS for P0983 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate PASSED?
Yes - Troubleshooting is complete. If any other DTCs were indicated on step 23, go to the indicated DTC's troubleshooting.
No - Check for poor connections and loose terminals at shift solenoid valve D and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 22 and recheck.
