P0983
DTC P0983: Open in Shift Solenoid Valve D Circuit2005-2006 Models
NOTE:
^ Record all freeze data and review General Troubleshooting Information before you troubleshoot.
^ 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 the P position.
3. Check that DTC P0983 recurs.
Is DTC P0983 indicated?
YES - Go to step 7.
NO - Go to step 4.
4. Choose Shift Solenoid D in Miscellaneous Test Menu, and test the shift solenoid valve D with the HDS.
5. Start the engine in the P position.
6. Monitor the OBD status for P0983 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate a 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 PCM. If the tester indicates NOT COMPLETED, return to step 4 and recheck.
7. Turn the ignition switch OFF.
8. Jump the SCS line with the HDS.
9. Disconnect PCM connectors A (31P) and C (22P).
10. Measure the resistance between PCM connector terminals C5 and A9.
Is there 12 - 25 ohms?
YES - Check for loose or poor connections at PCM connector terminal C5. If the connection is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
NO - Go to step 11.
11. Disconnect the shift solenoid harness connector at the transmission housing.
12. Measure the resistance between shift solenoid harness connector terminal No. 8 and body ground.
Is there 12 - 25 ohms?
YES - Repair open in the wire between PCM connector terminal C5 and the shift solenoid harness connector, then go to step 13.
NO - Check shift solenoid valve D, and check for an open in the shift solenoid harness in the transmission. Replace shift solenoid valve D and/or shift solenoid harness, then go to step 13.
13. Clear the DTC with the HDS.
14. Start the engine in the P position.
15. Monitor the OBD status for P0983 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate a passed?
YES - Troubleshooting is completed.
NO - Return to step 7 and recheck.
