CHECK UD SOLENOID POWER SUPPLY
• Turn ignition switch on.
• Check UD solenoid power supply between E-086
terminal 9 and ground in the A/T assembly connec-
tor E-086.
• Voltage should be more than 12 V.
Is the check result normal?
Yes
>>
Go to step 6.
No
>>
Go to the next step.
5.
DETECT MALFUNCTIONING PART
• Check the following:
− Harness connectors A-102, E-105.
− Body fuse and relay box H9, H8, G15.
− Fuse 10 (30A).
− Harness for an open or short between A/T assembly connector and fuse.
Is the check result normal?
Yes
>>
Go to the next step.
No
>>
Repair or replace the open circuit or short to ground or short to power in harness or connectors.
6.
CHECK UD 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

1
Yes
• Check the harness for short to power and short to ground.
Is the check result normal?
Yes
>>
Go to the next step.
No
>>
Repair or replace the circuit for an open or short to power or short to ground.

7.
CHECK DTC
• With the X-431 scan tool, read TCM DTCs.
• Refer to ⬙DTC Confirmation Procedure⬙.
Is DTC 32 still present?
Yes
>>
Replace the TCM.
No
>>
The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.

CONDITION
POSSIBLE CAUSES
33
2nd Gear solenoid
open circuit
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.
• If the DTC was
set, then the A/T will
be locked at 3rd
gear (D gear).
• Solenoid
• Harness or
connectors (The
sensor circuit is open
or shorted)
• TCM
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 ⬙D⬙ position.
• 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.
