Acura RL. Manual - part 268

YES - Go to step 13.

NO - Repair open in the wire between PCM connector terminal C16 and the shift solenoid harness
connector, then go to step 20.

13. Remove the shift solenoid harness connector (see SHIFT SOLENOID VALVE TEST AND

REPLACEMENT ).

14. Check for continuity between shift solenoid harness connector terminal No. 2 and the shift solenoid valve

C connector terminal.

Is there continuity?

YES - Replace shift solenoid valve C (see SHIFT SOLENOID VALVE TEST AND
REPLACEMENT ), then go to step 20.

NO - Replace the shift solenoid harness (see SHIFT SOLENOID VALVE TEST AND
REPLACEMENT ), then go to step 20.

15. Connect PCM connectors A (31P), B(24P), and C (22P).

16. Update the A/T software in the PCM if it does not have the latest software (see UPDATING THE

PCM ), or substitute a known-good PCM (see SUBSTITUTING THE PCM ).

17. Start the engine in P, wait for at least 1 second, then test-drive the vehicle in D. Run the vehicle in 1st

gear at least 1 second, then slow down to a stop. Put the shift lever into N or P.

18. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.

Is DTC P0980 indicated?

YES - If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ),
then recheck. If the PCM was substituted, go to step 1.

NO - Go to step 19.

19. Monitor the OBD STATUS for P0980 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 (see PCM REPLACEMENT ). If any other DTCs were indicated on step 18, go to the
INDICATED DTCS TROUBLESHOOTING.

NO - Check for poor connections and loose terminals at shift solenoid valve C and the PCM. If the PCM
was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then recheck. If the
PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 17 and
recheck.

20. Clear the DTC with the HDS.

21. Start the engine in P, wait for at least 1 second, then test-drive the vehicle in D. Run the vehicle in 1st

gear at least 1 second, then slow down to a stop. Put the shift lever into N or P.

22. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.

Is DTC P0980 indicated?

YES - Check for poor connections and loose terminals at shift solenoid valve C and the PCM, then go to
step 1.

NO - Go to step 23.

23. Monitor the OBD STATUS for P0980 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 22, go to the INDICATED
DTCS TROUBLESHOOTING.

NO - Check for poor connections and loose terminals at shift solenoid valve C and the PCM, then go to
step 1. If the HDS indicates NOT COMPLETED, return to step

and recheck.

DTC P0982: Short in Shift Solenoid Valve D Circuit

1. Clear the DTC with the HDS.

2. Start the engine in P, and wait for at least 1 second.

NOTE:



Before you troubleshoot, record all freeze data and any on-board
snapshot, and review General Troubleshooting Information (see GENERAL
TROUBLESHOOTING INFORMATION ).



This code is caused by an electrical circuit problem and cannot be caused
by a mechanical problem in the transmission.

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 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/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate FAILED?

YES - Go to step 7.

NO - Intermittent failure, the system is OK at this time. Check the SH D 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 connectors A (31P), B (24P), and C (22P).

10. Measure the resistance between PCM connector terminals C2 and A3 or B15.

Is there less than 12 ohms?

YES - Go to step 11.

NO - Go to step 19.

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

12. Check for continuity between PCM connector terminals C2 and A3 or B15.

Is there continuity?

YES - Repair short in the wire between PCM connector terminal C2 and the shift solenoid harness
connector, then go to step 24.

NO - Go to step 13.

13. Inspect shift solenoid valve D (see SHIFT SOLENOID VALVE TEST AND REPLACEMENT ).

Is shift solenoid valve D OK?

YES - Go to step 14.

NO - Replace shift solenoid valve D or the shift solenoid harness (see SHIFT SOLENOID VALVE
TEST AND REPLACEMENT ), then go to step 16.

14. Disconnect PCM connector D (17P).

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

16. Measure the voltage between PCM connector terminals D12 and A3 or B15.
