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). •

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 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:

Gear 1 Off On Off On Off
Gear 2 On Off Off On On
Gear 3 On Off Off Off On
Gear 4 On Off On Off On
Reverse gear Off On On On Off
Neutral gear/
Parking Off On On On Off
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.
Is the check result normal?
Ye s>>Go to step 7.
No
>>Go to the next step.

E-086 terminal 9 and ground in the A/T assembly
connector 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:
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?
Ye s>>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 2ND GEAR 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

6Yes
• 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 open circuit or short to power or short to ground.
