ON

NOTE:

• Before you troubleshoot, record all freeze data and

any on-board snapshot, and review General
Troubleshooting Information (see page 14-4).

• 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.

2. Check the 3RD PRESSURE SWITCH SIGNAL with

the HDS in the A/T data list when not in 3rd gear.

Go to step 3.

Go to step 6.

3. Start the engine, and warm it up to normal

operating temperature (the radiator fan comes on).

4. Drive the vehicle in 3rd gear in D in the D3 driving

mode for at least 2 seconds, then release the D3
driving mode by pressing the D3 switch, and drive
in 4th gear for at least 2 seconds. Slow down and
stop the wheels.

5. Monitor the OBD STATUS for P0847 in the DTCs

MENU with the HDS.

Intermittent failure, the system is OK at this

time. Check the OP3SW (BLU/WHT) wire for an
intermittent short to ground between the 3rd clutch
transmission fluid pressure switch and the PCM.

If the screen indicates FAILED, go to step 6. If

the screen indicates NOT COMPLETED, return to
step 3 and recheck.

6. Turn the ignition switch to LOCK (0).

7. Disconnect the 3rd clutch transmission fluid

pressure switch connector.

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

9. Check the 3RD PRESSURE SWITCH SIGNAL with

the HDS in the A/T data list.

Go to step 14.

Go to step 10.

10. Turn the ignition switch to LOCK (0).

11. Jump the SCS line with the HDS.

12. Disconnect PCM connector C (44P).

13. Check for continuity between PCM connector

terminal C15 and body ground.

Repair a short to ground in the wire between

PCM connector terminal C15 and the 3rd clutch
transmission fluid pressure switch, then go to
step 15.

Go to step 22.

DTC Troubleshooting (cont’d)

14. Replace the 3rd clutch transmission fluid pressure

switch (see page 14-206).

15. Reconnect all connectors.

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

17. Clear the DTC with the HDS.

18. Start the engine, and warm it up to normal

operating temperature (the radiator fan comes on).

19. Drive the vehicle in 3rd gear in D in the D3 driving

mode for at least 2 seconds, then release the D3
driving mode by pressing the D3 switch, and drive
in 4th gear for at least 2 seconds. Slow down and
stop the wheels.

20. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals at the 3rd clutch transmission fluid
pressure switch and the PCM, then go to step 1.

If Temporary DTC or DTC P0847 is not

indicated, or if any other Temporary DTCs are
indicated, go to step 21.

21. Monitor the OBD STATUS for P0847 in the DTCs

MENU with the HDS.

Troubleshooting is complete. If any other

Temporary DTC or DTC s were indicated on step 20,
go to the indicated DTCs troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at the 3rd clutch
transmission fluid pressure switch and the PCM,
then go to step 1. If the screen indicates NOT
COMPLETED, go to step 18.

22. Update the PCM if it does not have the latest

software (see page 14-8), or substitute a known-
good PCM (see page 14-9).

23. Start the engine, and warm it up to normal

operating temperature (the radiator fan comes on).

24. Drive the vehicle in 3rd gear in D in the D3 driving

mode for at least 2 seconds, then release the D3
driving mode by pressing the D3 switch, and drive
in 4th gear for at least 2 seconds. Slow down and
stop the wheels.

25. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals at the 3rd clutch transmission fluid
pressure switch and the PCM. If the PCM was
updated, substitute a known-good PCM (see page
14-9), then go to step 23. If the PCM was substituted,
go to step 1.

If Temporary DTC or DTC P0847 is not

indicated, or if any other Temporary DTCs or DTCs
are indicated, go to step 26.

26. Monitor the OBD STATUS for P0847 in the DTCs

MENU with the HDS.

If the PCM was updated, troubleshooting is

complete. If the PCM was substituted, replace the
original PCM (see page 11-205). If any other
Temporary DTCs or DTCs were indicated on step
25, go to the indicated DTCs troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at the 3rd clutch
transmission fluid pressure switch and the PCM. If
the PCM was updated, substitute a known-good
PCM (see page 14-9), then go to step 23. If the PCM
was substituted, go to step 1. If the screen indicates
NOT COMPLETED, go to step 23.
