terminals at A/T clutch pressure control solenoid
valve C and the PCM, then go to step 1.
If Temporary DTC or DTC P0970 is not
indicated, or if any other Temporary DTCs are
indicated, go to step 19.
19. Monitor the OBD STATUS for P0970 in the DTCs
MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTC or DTCs were indicated on step 18,
go to the indicated DTCs troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at A/T clutch
pressure control solenoid valve C and the PCM,
then go to step 1. If the screen indicates NOT
COMPLETED, go to step 17.
20. 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).
21. Start the engine, and wait for at least 1 second.
22. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at A/T clutch pressure control solenoid
valve C and the PCM. If the PCM was updated,
substitute a known-good PCM (see page 14-9), then
go to step 21. If the PCM was substituted, go to step
1.
If Temporary DTC or DTC P0970 is not
indicated, or if any other Temporary DTCs or DTCs
are indicated, go to step 23.

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
22, go to the indicated DTCs troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at A/T clutch
pressure control solenoid valve C and the PCM. If
the PCM was updated, substitute a known-good
PCM (see page 14-9), then go to step 21. If the PCM
was substituted, go to step 1. If the screen indicates

Control Solenoid Valve C
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. Start the engine, and wait for at least 1 second.
3. Check that DTC P0971 recurs.
Go to step 7.
Go to step 4.
4. Select CLUTCH PRESSURE CONTROL SOLENOID C
in MISCELLANEOUS TEST MENU, and test A/T
CLUTCH PRESSURE CONTROL SOLENOID VALVE
C with the HDS.
Go to step 5.
Go to step 7.
5. Command A/T CLUTCH PRESSURE CONTROL
SOLENOID VALVE C at 0.2 A in CLUTCH
PRESSURE CONTROL SOLENOID CONTROL
MENU with the HDS.
6. Monitor the OBD STATUS for P0971 in the DTCs
MENU with the HDS.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at A/T clutch pressure control solenoid valve C and
the PCM.
If the screen indicates FAILED, go to step 7. If
the screen indicates NOT COMPLETED, return to
step 4 and recheck.
7. Turn the ignition switch to LOCK (0).
8. Disconnect the A/T clutch pressure control solenoid
valve C connector.
9. Measure the resistance between A/T clutch
pressure control solenoid valve C connector
terminals No. 1 and No. 2.
Go to step 10.
Go to step 11.

10. Check for continuity between A/T clutch pressure
control solenoid valve C connector terminal No. 2
and body ground.
Go to step 18.
Repair open in the wire between A/T clutch
pressure control solenoid valve C and ground
(G101, G102) (see page 22-18), or repair poor
ground (G101, G102), then go to step 12.
