terminal 10 and ground in the A/T assembly con-
nector E-086.
• Voltage should be more than 12 V.
Is the check result normal?
Ye s>>Go to step 6.
No
>>Go to the next step.
5.DETECT MALFUNCTIONING PART
• Check the following:
Fuse 10 (30A).
Harness connectors A-102, E-105.
Body fuse and relay box H9, H8, G15.
Harness for an open or short between A/T assembly connector and fuse.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace the circuit for an open or short to ground or short to power in harness or connec-
tors.
6.CHECK OD SOLENOID CONTROL CIRCUIT
• Turn ignition switch off.
• Disconnect TCM connector.
• Check for harness continuity between the following terminals:
A/T ASSEMBLY
TERMINAL TCM
CONNECTOR TERMINAL CONTINUITY
65
4Yes
• Check the harness for short to power and short to ground.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace the circuit for an open or short to power or short to ground.

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.
• If the DTC 36 was set, then the
A/T will be locked in 3rd gear (D
gear). •

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.

1.CHECK A/T SOLENOID SIGNAL
• 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:

Is the check result normal?
Ye s>>The condition that caused this DTC is intermittent (See Diagnostic Help in Section 08 Transaxle &
Transfer Case).
No
>>Go to the next step.
2.ACTUATE TEST
• With X-431, perform the solenoid actuate test.
• The solenoid should be heard.
