connectors (The
sensor circuit is open
or shorted)
• 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.

• Turn ignition switch off.
• Disconnect the A/T assembly electrical connector
E-037 (1).
• Disconnect the TCM electrical connector E-036.
• Inspect the electrical connectors for damage.
Is the electrical connector OK?
Ye s>>Go to the next step.
No
>>Repair or replace the electrical connector
as necessary.
4.CHECK SOLENOID POWER SUPPLY
• Check the solenoid power circuit for battery voltage
between the A/T assembly electrical connector
E-037 terminal B3 and ground.
Is battery voltage present?
Ye s>>Repair the circuit for a short to voltage in
the harness or connectors.
No
>>Go to the next step.
5.CHECK DTC
• Reconnect all previously disconnected electrical connectors.
• Start and operate the vehicle.
• With the X-431 scan tool, read TCM DTCs.
• Refer to DTC Confirmation Procedure.
Did DTC P0657 reset?
Ye s>>Replace the TCM.
No
>>The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.
