DTC Troubleshooting: P0982 (60)

DTC P0982: Short in Shift Solenoid Valve D Circuit

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information. How to Troubleshoot A/T Systems

- 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.

3. Check that DTC P0982 recurs.

Is DTC P0982 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.

6. Monitor the OBD STATUS for P0982 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 - If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check the SHD wire for an intermittent short to ground between 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 (49P) and C (49P).

10. Measure the resistance between PCM connector terminals C9 and C41 or B41.

Is there less than 12 Ohms?
YES - Go to step 11.

NO - Go to step 19.






11. Disconnect the shift solenoid harness connector.

12. Check for continuity between PCM connector terminals C9 and C41 or B41.

Is there continuity?
YES - Repair short in the wire between PCM connector terminal C9 and the shift solenoid harness connector, then go to step 24.

NO - Go to step 13.






13. Inspect shift solenoid valve D. A/T Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement

Is shift solenoid valve D OK?
YES - Go to step 14.

NO - Replace shift solenoid valve D or the shift solenoid harness, A/T Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement then go to step 24.


14. Disconnect PCM connector A (49P).

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

16. Measure the voltage between PCM connector terminals A1 and B41 or C41.

Is there battery voltage?
YES - Go to step 19.

NO - Go to step 17.






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

18. Check for continuity between PCM connector terminals B41 and body ground, and between C41 and body ground.

Is there continuity?
YES - Check for a blown No. 10 fuse in the under-dash fuse/relay box. If the fuse is OK, repair open in the wire between PCM connector terminal A1 and the under-dash fuse/relay box, then go to step 24.

NO - Repair open in the wires between PCM connector terminals B41, C41 and ground (G101), or repair poor ground (G101), then go to step 24.






19. Reconnect all connectors.

20. Update the A/T software in the PCM if it does not have the latest software, PCM Update or substitute a known-good PCM. How to Troubleshoot A/T Systems

21. Start the engine in P.

22. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0982 indicated?
YES - If the PCM was updated, substitute a known-good PCM, How to Troubleshoot A/T Systems then recheck. If the PCM was substituted, go to step 1.

NO - Go to step 23.


23. Monitor the OBD STATUS for P0982 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. Service and Repair If any other DTCs were indicated on step 17, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, 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, How to Troubleshoot A/T Systems then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 21 and recheck.


24. Clear the DTC with the HDS.

25. Start the engine in P.

26. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0982 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 27.


27. Monitor the OBD STATUS for P0982 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 21, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, 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 20 and recheck.
