DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on.
• With the scan tool, record and erase stored DTCs in the TCM.
• Start engine and warm it to normal operating temperature.
• 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 :
• If using the appropriate diagnostic test tool, you can diagnose the TCM harness while the TCM is still connected.
• Using the appropriate diagnostic test tool in this way will help prevent electrical connector terminal damage.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK DTC AND TURBINE SPEED SENSOR DATA STREAM
• With the scan tool, select view DTC and data stream for A/T.
• Start the engine.
• Monitor the value of turbine speed sensor while driving.
Is the check result normal and DTC not present?
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.

>>Repair or replace the open circuit or short to power or short to ground in harness or connectors.
If circuit is normal, replace the TCM.
3.CHECK TURBINE SPEED SENSOR RESISTANCE
• Check the resistance of the turbine speed sensor between the turbine speed sensor electrical connector pin D1
and D2, component side.
