• Check the following:
Harness connectors A-102, E-105
Body fuse and relay box H9, H8, G15
Fuse 10 (30A)
Harness 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 R/L SOLENOID CONTROL CIRCUIT
• Turn the ignition switch off.
• Disconnect TCM connector.
• Check for harness continuity between the following terminals:
A/T ASSEMBLY
TERMINAL TCM
CONNECTOR TERMINAL CONTINUITY

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

The Transaxle
Control Module
(TCM) will set this

detected an
improper voltage
drop when it tries to
operate the solenoid
valve.

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 the engine and warm it to normal operating temperature.
• Drive the vehicle.
• 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.
