DTC Troubleshooting: P0982

DTC P0982: Shift Solenoid Valve D (Short)

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, and wait for at least 1 second.

3. Check if DTC P0982 records.

Is DTC P0982 indicated?
YES - Go to step 7.

NO - Go to step 4.


4. Select Shift Solenoid D in 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, and wait for at least 1 second.

6. Monitor the OBD STATUS for P0982 in the DTCs MENU with the HDS.

Does the HDS indicate FAILED?
YES - Go to step 7.

NO - Intermittent failure, the system is OK at this time. Check the SHD wire for an intermittent short 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 connector C (22P).

10. Measure the resistance between PCM connector terminal C2 and body ground.

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

NO - Go to step 16.






11. Disconnect shift solenoid harness connector at the transmission housing.

12. Check for continuity between PCM connector terminal C2 and body ground.

Is there continuity?
YES - Repair a short in the wire between PCM connector terminal C2 and the shift solenoid harness connector, then go to step 21.

NO - Go to step 13.






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

Is shift solenoid valve D and shift solenoid harness 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 21.


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

15. Measure the voltage between PCM connector terminal D12 and body ground.

Is there battery voltage?
YES - Go to step 16.

NO - Check for blown No. 20 fuse in the driver's under-dash fuse/relay box. If the fuse is OK, repair an open in the wire between PCM connector terminal D12 and the driver's under-dash fuse/relay box, then go to step 21.






16. Reconnect all connectors.

17. Update the A/T software in the PCM if it does not have the latest software, PCM Update or substitute a known-good PCM. Reading and Clearing Diagnostic Trouble Codes

18. Start the engine in P, and wait for at least 1 second. With the brake pedal pressed, shift to N, and wait for at least 1 second.

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

Is DTC P0982 indicated?
YES - If the PCM was updated, substitute a known-good PCM, Reading and Clearing Diagnostic Trouble Codes then recheck. If the PCM was substituted, go to step 1.

NO - Go to step 20.


20. Monitor the OBD STATUS for P0982 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 on step 19, 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, Reading and Clearing Diagnostic Trouble Codes then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 18 and recheck.


21. Clear the DTC with the HDS.

22. Start the engine in P, and wait for at least 1 second. With the brake pedal pressed, shift to N, and wait for at least 1 second.

23. Check for Pending or Confirmed 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 24.


24. Monitor the OBD STATUS for P0982 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 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.
