Short in 2nd Clutch Transmission

Fluid Pressure Switch Circuit, or 2nd Clutch
Transmission Fluid Pressure Switch Stuck
ON

NOTE:

• Record all freeze data and review General

Troubleshooting Information (see page 14-8) before
you troubleshoot.

• 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 2nd PRES SWITCH signal with the HDS in

the A/T data list when not in 2nd gear.

Go to step 3.

Go to step 5.

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

operating temperature (the radiator fan comes on).
Drive the vehicle in 2nd gear in the M position for
more than 5 seconds, then upshift to 4th gear, and
drive in 4th gear for more than 5 seconds. Slow
down to a stop.

4. Monitor the OBD status for P0842 in the DTCs/

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

Go to step 5.

Intermittent failure, the system is OK at this

time. Check the BLU/RED wire for an intermittent
short to ground between the 2nd clutch
transmission fluid pressure switch and PCM. If the
tester indicates NOT COMPLETED, return to step 3
and recheck.

5. Turn the ignition switch OFF.

6. Disconnect the 2nd clutch transmission fluid

pressure switch connector.

7. Turn the ignition switch ON (II).

8. Check the 2nd PRES SWITCH signal with the HDS in

the A/T data list.

Replace the 2nd clutch transmission fluid

pressure switch (see page 14-267), then go to step
13.

Go to step 9.

9. Turn the ignition switch OFF.

10. Jump the SCS line with the HDS.

11. Disconnect PCM connector C (22P).

12. Check for continuity between PCM connector

terminal C13 and body ground.

Repair short to ground in the wire between

PCM connector terminal C13 and the 2nd clutch
transmission fluid pressure switch, then go to step
13.

Update the PCM if it does not have the latest

software, or substitute a known-good PCM
(see page 14-11), then recheck. If the symptom/
indication goes away with a known-good PCM,
replace the original PCM.

OFF

NOTE:

• Record all freeze data and review General

Troubleshooting Information (see page 14-8) before
you troubleshoot.

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

operating temperature (the radiator fan comes on).
Shift into the M position 2nd gear while pressing
the brake pedal, and verify that the SHIFT MAP
NUMBER indicates 2nd with the HDS in the A/T
data list.

3. Check the 2nd PRES SWITCH signal with the HDS in

the A/T data list.

Go to step 4.

Go to step 6.

4. Drive the vehicle in 2nd gear in the M position for

more than 5 seconds, then upshift to 4th gear, and
drive in 4th gear for more than 5 seconds. Slow
down to a stop.

5. Monitor the OBD status for P0843 in the DTCs/

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

Go to step 6.

Intermittent failure, the system is OK at this

time. Check for poor connections or loose terminals
at the 2nd clutch transmission fluid pressure switch
and PCM. If the tester indicates NOT COMPLETED,
return to step 4 and recheck.

6. Turn the ignition switch OFF.

7. Disconnect the 2nd clutch transmission fluid

pressure switch connector.

8. Turn the ignition switch ON (II).

9. Measure the voltage between the 2nd clutch

transmission fluid pressure switch connector
terminal and body ground.

Replace the 2nd clutch transmission fluid

pressure switch (see page 14-267), then go to step
11.

Go to step 10.
