13. Clear the DTC with the HDS.

14. Start the engine, and shift the transmission in 2nd gear in the M position.

15. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0982.

Did the result indicate a pass?

YES: The problem has been corrected.

NO: Return to step 1 and recheck.

DTC P0983: OPEN IN SHIFT SOLENOID VALVE D CIRCUIT

1. Clear the DTC with the HDS.

2. Start the engine in the P position.

3. Check that DTC P0983 recurs.

NOTE:

Record all freeze data and review General Troubleshooting Information
(see 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.

Is DTC P0983 indicated?

YES: Go to step 7 .

NO: Go to step 4.

4. Select SHIFT SOL TEST in MISC. TEST MENU, then carry out A/T SHIFT SOL D test in SHIFT SOL

TEST MENU with the HDS.

5. Start the engine in the P position.

6. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0983.

Did 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.

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 A8 or A9.

Is there 12-25 ohm?

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 (see PCM UPDATING & SUBSTITUTION FOR TESTING ), 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 ohm?

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 (see SHIFT SOLENOID VALVE TEST ). 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. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0983.

Did the result indicate a pass?

YES: The problem has been corrected.

NO: Return to step 1 and recheck.
