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 diagnostic connector, press the POWER key to start the X-431.
• 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.
Diagnostic Procedure
1.CHECK A/T SOLENOID SIGNAL
• With the scan tool, select view DTC and data stream for A/T.
• Start the engine.
• Monitor the value of the gear position as indicated in the following table while driving:

Ye s>>The condition that caused this DTC is intermittent (See Diagnostic Help in Section 08 Transaxle &
Transfer Case).
No
>>Go to the next step.
2.ACTUATE TEST
• With X-431, perform the solenoid actuate test.
• The solenoid should be heard.
Is the check result normal?
Ye s>>Go to step 6.
No

Ye s>>Replace the valve with a known good one.
With X-431, perform the solenoid actuate test.
If the solenoid can be heard, go to step 6.
If the solenoid can’t be heard, go to the next step.
No
>>Replace the damaged solenoid valve.
4.CHECK SHIFT SOLENOID VALVE 6 (SSV6) POWER SUPPLY
• Turn the ignition switch on.
• Check power supply between SSV6 E-037 terminal
B2 and ground in the A/T assembly connector
E-037.
• Battery voltage should exist.
• Or using the appropriate diagnostic test tool and a digital multimeter perform the following:
• Check the EVS6 solenoid supply voltage between TCM pin 1 and TCM pin 14 when activating the EVS6 sole-
noid and deactivating the EVS6 solenoid.
• Check the shift solenoid control signal. Check the voltage of the shift solenoid in each shift position.
• Check the voltage of the EVS6 solenoid supply circuit between the transaxle assembly electrical connector pin
B3 and pin B2.
