• Turn the ignition switch on.
• Check the A/T fluid pressure sensor voltage supply
circuit for 5 V between connector E-037, terminal
C1 and ground.
• Check the Transaxle Fluid Temperature (TFT) sen-
sor voltage supply circuit for 5 V between connec-
tor E-037, terminal B1 and ground.
Is 5 V present at each terminal?
Ye s>>• Go to the next step.
No
>>• Repair or replace open circuit or short
to ground or short to power in harness
or connectors.
3.CHECK A/T FLUID PRESSURE SENSOR AND TFT SENSOR GROUND CIRCUIT
• Disconnect the Transaxle Control Module (TCM) electrical connector E-036 (1).
• Check the A/T fluid pressure sensor ground circuit
between the A/T connector E-037, terminal C3 and
TCM connector E-036 terminal 25 for an open,
short to ground or short to voltage.
• Check the A/T TFT sensor ground circuit between
the A/T connector E-037, terminal B4 and TCM
connector E-036 terminal 53 for an open, short to
ground or short to voltage.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair the circuit for an open or short to
ground or short to voltage in the harness or
connectors.

• Transaxle Control
Module (TCM)
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.
• 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 :
Using the appropriate diagnostic test tool, you can diagnose the TCM harness while the TCM is still connected. This
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.
