5Yes
• 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.

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.
