14. Reconnect all connectors.

15. Turn the ignition switch ON (II).

16. Clear the DTC with the HDS.

17. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).

18. Drive the vehicle in 2nd gear in the D position for at least 2 seconds, then drive in 4th gear for at least 2

seconds.

19. Turn the ignition switch OFF, and repeat the test-drive in step 18.

20. Check for DTCs with the HDS.

Is DTC P0843 indicated?

YES -Check for poor connections or loose terminals between the 2nd clutch transmission fluid pressure
switch and the PCM, then go to step 1.

NO -Go to step 21.

21. Monitor the OBD STATUS for P0843 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

DTCs troubleshooting.

NO -If the screen indicates FAILED, check for poor connections or loose terminals between the 2nd
clutch transmission fluid pressure switch and the PCM, then go to step 1. If the screen indicates NOT
COMPLETED, go to step 17.

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, and warm it up to normal operating temperature (the radiator fan comes on).

24. Drive the vehicle in 2nd gear in the D position for at least 2 seconds, then drive in 4th gear for at least 2

seconds.

25. Turn the ignition switch OFF, and repeat the test-drive in step 24.

26. Check for DTCs with the HDS.

Is DTC P0843 indicated?

YES -Check for poor connections or loose terminals between the 2nd clutch transmission fluid pressure
switch 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 27.

27. Monitor the OBD STATUS for P0843 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the
original PCM (see ECM/PCM REPLACEMENT ). If any other DTCs were indicated in step 26, go to
the indicated DTCs troubleshooting.

NO -If the screen indicates FAILED, check for poor connections or loose terminals between the 2nd
clutch transmission fluid pressure switch 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. If
the screen indicates NOT COMPLETED, go to step 23.

DTC P0847: SHORT IN 3RD CLUTCH TRANSMISSION FLUID PRESSURE SWITCH CIRCUIT, OR
3RD CLUTCH TRANSMISSION FLUID PRESSURE SWITCH STUCK ON

1. Turn the ignition switch ON (II).

NOTE:



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