DTC Troubleshooting: P0983 (60-4)

DTC P0983: Open in Shift Solenoid Valve D Circuit 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. Clear the DTC with the HDS. Start the engine in the P position. Check that DTC P0983 recurs. Is DTC P0983 indicated?
YES | - | Go to Step 7 .
NO | - | Go to Step 4 .
Choose Shift Solenoid D in Miscellaneous Test Menu, and test the shift solenoid valve D with the HDS. Start the engine in the P position. 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 fail?
YES | - | Go to Step 7 .
NO | - | Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the shift solenoid valve D and PCM. If the tester indicates NOT COMPLETE, return to Step 4 and recheck.■
Turn the ignition switch OFF. Jump the SCS line with the HDS. Disconnect PCM connectors A (31P) and C (22P). Measure the resistance between PCM connector terminals C5 and A8 or A9. Is there 12−25 Ω?
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 .
Disconnect the shift solenoid harness connector at the transmission housing. |

Measure the resistance between shift solenoid harness connector terminal No. 8 and body ground. Is there 12−25 Ω?
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 .
Clear the DTC with the HDS. Start the engine in the P position. 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 pass?
YES | - | The problem has been corrected.■
NO | - | Return to Step 1 and recheck.■
