Is the check result normal?
Yes
>>
Go to the next step.
No
>>
Repair or replace short to power supply in harness or connectors.
6.
CHECK DTC
• With the X-431 scan tool, read TCM DTCs.
• Refer to ⬙DTC Confirmation Procedure⬙.
Is DTC P0773 present?
Yes
>>
Replace the TCM.
No
>>
The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.

The Transaxle Control Module
(TCM) will set this DTC when the
TCM detected an improper voltage
drop when it tries to operate the
solenoid valve.

DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• After connection, press [POWER] key to start X-431.
• 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 in 1st, 2nd, 3rd and 4th gears.
• 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.
