(DCC) solenoid malfunction Vehicle is driving •
The Transaxle Control Module
(TCM) will set this DTC when the
TCM detected an improper voltage
drop when it tries to operate the
solenoid valve.
• The Transaxle Control Module
(TCM) will set this DTC when the
TCM detected that the duty cycle of
damper clutch system control
solenoid is 100 % for 4 seconds,
and the TCM determines the
damper clutch system control
solenoid is not normal.

DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• After connection, press POWER key to start X-431.
• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the TCM.
• Start engine and warm it to normal operating temperature, then select Dposition.
• Drive the vehicle in 1st, 2nd, 3rd and 4th gears.
• With the scan tool, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 08 Transaxle & Transfer Case for more information).
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.

NOTE :
Checking the automatic transaxle fluid quality and fluid level is the most basic check of the automatic transaxle. The
fluid check is also an important inspection to determine if the transaxle will need to be disassembled.
CAUTION:
The burnt scent of ATF fluid indicates that the transaxle fluid is contaminated. The tiny particles in
the fluid pan indicate that the transaxle is worn out and it will be necessary to overhaul the trans-
axle.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK FLUID QUALITY AND FLUID LEVEL AND DTC
• Drive the vehicle, until the ATF reaches operating temperature (70° - 80°C).
• Park the vehicle on level ground.
• Shift the gear selector lever to all gear positions once, then shift to gear “N”.
• Clean and check the outside of the dipstick and remove the dipstick to check the fluid level.
• With the scan tool, select view DTC and data stream for A/T.
• Start the engine.
• Monitor the value of the gear position as indicated in the following table while driving:
