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.

• 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.

•Refill the transaxle fluid through the fill hole (1)
shown in the figure.
• To avoid fluid spills, make sure to use a funnel.
• Add 3.5 L of new automatic transaxle fluid into the transaxle.
• Start the engine and maintain an idle.
• Connect the X-431 scan tool and establish a connection with the TCM and monitor the transaxle fluid tempera-
ture.
• Open the drain plug (2) when the fluid temperature reaches 60 ± 1°. Loosen the fluid limiting duct (1) if neces-
sary.
• Catch any fluid that drains out with a measuring cup.
• If no fluid drains out, or the drained fluid is less than 0.1 liter perform the following:
1. Turn off the ignition switch.
2. Add 0.5 liter fluid to the transaxle.
3. Allow the transaxle fluid to cool down to 50°C.
4. Start the engine and maintain an idle.
5. Open the drain plug when the fluid temperature reaches 60 ± 1°C.
6. Catch any fluid that drains out with a measuring cup.
7. Repeat the above steps, until the drained fluid exceeds 0.1 liter.
8. Tighten the drain plug to 33 N·m.
