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.
• 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).
• If using the appropriate diagnostic test tool, you can diagnose the TCM harness while the TCM is still con-
nected.
• 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.

Description
The transaxle gear train is comprised of two rows of planetary gear set, one one-way clutch and five actuators (three
composite disc clutches and two composite disc brakes.
It is controlled with adaptive electronic controls and monitors. The hydraulic system of the transaxle consists of the
transaxle fluid, fluid passages, hydraulic valves, fluid pump, and various line pressure control components.
The Transaxle Control Module (TCM) is the heart of the electronic control system and relies on information from
various direct and indirect inputs (sensors, switches, etc.) to determine driver demand and vehicle operating condi-
tions. With this information, the ECM/TCM can calculate and perform timely and quality shifts through various output
or control devices.
The TCM also performs certain self-diagnostic functions and provides comprehensive information (sensor data,
DTCs, etc.) which is helpful in proper diagnosis and repair. This information can be viewed with the X-431 scan tool.

Diagnostic Help
1. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.
2. If the DTC cannot be deleted, it is a current fault.
3. Use a digital multimeter to perform voltage readings on the transaxle electronic system.
4. The scan tool connects to the Data Link Connector (DLC) and communicates with the Transaxle Control Module(TCM) over the CAN data circuit.
5. If the failure is intermittent, perform the following: •Check for loose connectors.
• Look for any chafed, pierced, pinched, or partially broken wires.
• Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
• Look for the data to change or for the DTC to reset during the wiggle test.
• Look for broken, bent, pushed out or corroded terminals.
• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as
damage or foreign material.
6. Remove the TCM from the troubled vehicle and install in a new vehicle and test. If the DTC cannot be deleted, the TCM is malfunctioning. If the DTC can be deleted, return the TCM to the original vehicle.
Diagnostic Tools
Diagnostic Scan Tool X-431
Read the following when connecting the X-431 scan tool:
•Connect the scan tool to the Data Link Connector (DLC) for communication with the vehicle.
• The DLC is located on the driver side compartment under the steering column (it is attached to the instrument
panel and accessible from the driver seat).
• The DLC is rectangular in design and capable of accommodating up to 16 terminals.
• The electrical connector has keying features to allow easy connection.
TCM Electrical Harness Test Tool
If using a TCM electrical harness test tool, you can diagnose the TCM harness while the TCM is still connected.
•Measure sensor and solenoid resistance (always measure resistance with the power off).
• Measure the signal voltage of the TCM (always measure voltage with the power on).
NOTE :
Using the TCM electrical harness test tool will help prevent electrical connector terminal damage.
