Honda Civic. Manual — part 230

Is DTC P0983 indicated?

YES -Go to step 8.

NO -Go to step 5.

5. Select Shift Solenoid Valve D in the Miscellaneous Test Menu, and test shift

solenoid valve D with the HDS.

Is a clicking sound heard?

YES -Go to step 6.

NO -Go to step 8.

6. Start the engine, then shift to N while pressing the brake pedal, and wait for at

least 1 second.

7. Monitor the OBD STATUS for P0983 in the DTCs MENU with the HDS.

Does the HDS indicate FAILED?

YES -Go to step 8.

NO -If the HDS indicates PASSED, intermittent failure, the system is OK at
this time. Check for poor connections or loose terminals between shift solenoid
valve D and the PCM. If the HDS indicates NOT COMPLETED, go to step 5.

8. Turn the ignition switch to LOCK (0).
9. Jump the SCS line with the HDS.

10. Disconnect PCM connectors B (44P) and C (44P).
11. Measure the resistance between PCM connector terminals B11 and C40.

Is there 12-25 ohms?

YES -Go to step 22.

NO -Go to step 12.

12. Disconnect the shift solenoid harness connector.
13. Check for continuity between PCM connector terminal B11 and shift solenoid

harness connector terminal No. 8.

NO -Repair open in the wire between PCM connector terminal B11 and the
shift solenoid harness connector, then go to step 16.

14. Remove the shift solenoid harness (see SHIFT SOLENOID VALVE AND

SHIFT SOLENOID WIRE HARNESS REPLACEMENT ).

15. Check for continuity between shift solenoid harness connector terminal No. 8

and the shift solenoid valve D connector terminal.

Is there continuity?

YES -Replace shift solenoid valve D (see SHIFT SOLENOID VALVE AND
SHIFT SOLENOID WIRE HARNESS REPLACEMENT ), then go to step
16.

NO -Replace the shift solenoid harness (see SHIFT SOLENOID VALVE
AND SHIFT SOLENOID WIRE HARNESS REPLACEMENT ), then go
to step 16.

16. Reconnect all connectors.
17. Turn the ignition switch to ON (II).
18. Clear the DTC with the HDS.
19. Start the engine, then shift to N while pressing the brake pedal, and wait for at

least 1 second.

20. Check for DTCs with the HDS.

Is DTC P0983 indicated?

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

NO -Go to step 21.

21. Monitor the OBD STATUS for P0983 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES -Troubleshooting is complete. If any other DTCs were indicated in step
20, go to the INDICATED DTC'S TROUBLESHOOTING.

NO -If the HDS indicates FAILED, check for poor connections or loose
terminals between shift solenoid valve D and the PCM, then go to step 1. If the
HDS indicates NOT COMPLETED, go to step 19.

22. Update the PCM if it does not have the latest software (see UPDATING THE

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

23. Start the engine, then shift to N while pressing the brake pedal, and wait for at

least 1 second.

24. Check for DTCs with the HDS.

Is DTC P0983 indicated?

YES -Check for poor connections or loose terminals between shift solenoid
valve D and the PCM. If the PCM was updated, substitute a known-good PCM
(see SUBSTITUTING THE PCM ), then go to step 23. If the PCM was
substituted, go to step 1.

NO -Go to step 25.

25. Monitor the OBD STATUS for P0983 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?
