DTC Troubleshooting: P0985 (61-3)

DTC P0985: Short in Shift Solenoid Valve E 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.

1. Clear the DTC with the HDS.

1. Start the engine in the P position.

1. Check that DTC P0985 recurs.

Is DTC P0985 indicated?

YES | - | Go to Step 7 .
NO | - | Go to Step 4 .

1. Choose Shift Solenoid E in Miscellaneous Test Menu, and test the shift solenoid valve E with the HDS.

1. Start the engine in the P position.

1. Monitor the OBD status for P0985 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 the YEL wire for an intermittent short to ground between the shift solenoid valve E and PCM. If the tester indicates NOT COMPLETE, return to Step 4 and recheck.■

1. Turn the ignition switch OFF.

1. Jump the SCS line with the HDS.

1. Disconnect PCM connectors A (31P) and C (22P).

1. Measure the resistance between PCM connector terminals C3 and A8 or A9.

Is there less than 12 Ω?

YES | - | Go to Step 11 .
NO | - | 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 .■

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

1. Check for continuity between PCM connector terminals C3 and A8 or A9.

Is there continuity?

YES | - | Repair short to ground in the wire between PCM connector terminal C3 and the shift solenoid harness connector, then go to Step 13 .
NO | - | Check shift solenoid valve E, and check for a short in the shift solenoid harness in the transmission. Replace shift solenoid valve E and/or shift solenoid harness, then go to Step 13 .

1. Clear the DTC with the HDS.

1. Start the engine in the P position.

1. Monitor the OBD status for P0985 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.■
