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.
• 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 :
• Ensure that the battery is fully charged.
• Before performing any DTC diagnostic procedures, verify the TCM power and ground circuits are properly con-
nected.
• Before performing the diagnostic procedure, repair all other TCM DTCs first.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK GROUND CONNECTION
• Turn ignition switch off.
• Loosen and retighten ground screws on the body (See Ground Inspection in Section 12 Brakes).
• Inspect the ground connection C-201 mounting position (See Vehicle Wiring Harness Layout - Main Harness in
Section 16 Wiring).
Are the ground connections OK?
Ye s>>Go to the next step.
No
>>Repair or replace the ground connections.

• Turn ignition switch on.
• With the scan tool, select view TCM DTC and data stream.
Is DTC U0001 present?
Ye s>>Go to the next step.
No
>>The condition that caused this DTC is intermittent (See Diagnostic Help in Section 08 Transaxle &
Transfer Case).
Erase all codes and test drive the vehicle to verify the repair is complete.
3.CHECK OTHER MODULE DTC
• With the scan tool X-431, attempt to enter all the other CAN communication modules such as ECM, CAN con-
verter module.
• Read the CAN DTCs.
Were other modules DTCs found?
Ye s>>If all of the other modules have the same DTC CAN Communication, go to the next step.
If all of the other modules have the DTC Lost communication with TCM, and do not have the CAN
Communication, replace and program the TCM module.
No
>>Go to step 8.
4.CHECK CAN-BUS LINE TERMINAL RESISTANCE IN TCM
• Turn the ignition switch off.
• Disconnect the negative battery cable.
• Disconnect TCM connector.
• Check resistance between TCM connector 38 and 39.

• Connect the negative battery cable.
• Connect TCM and ECM connectors.
• Turn the ignition switch on.
• Check CAN-Bus voltage between the following terminals:
CAN-H 0.025 V should exist with bus communication inactive.
0.65 V should exist with bus communication active.
CAN-L 11 V should exist with bus communication inactive.
4.65 V should exist with bus communication active.
• Check CAN-Bus voltage between the following terminals:

No
>>Go to the next step.
7.CHECK CAN-BUS LINE
• Turn ignition switch off.
• Connect CAN converter.
• Disconnect ECM connectors.
• Turn ignition switch on.
• Check CAN-Bus voltage as the standard value.

•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.
