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.

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, view and erase stored DTCs in the TCM.
• Start the engine and warm it to normal operating temperature.
• Drive the vehicle up to 10 km/h or more.
• 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.
Diagnostic Procedure
1.CHECK TFT SENSOR RESISTANCE
• Turn ignition switch off.
• Disconnect A/T assembly connector E-086.
• Check TFT resistance between the TFT sensor terminals:
SENSOR CONNECTOR TERMINAL TEMPERATURE RESISTANCE
K
A/T sensor E-086 1 - 20°C
16.7 - 20.5
20°C 7.3 - 8.9
40°C 3.4 - 4.2
60°C 1.9 - 2.1
80°C 1.0 - 1.2
110°C 0.57 - 0.69
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace the TFT sensor.
