12. Replace the metal bracket of the fluid temperature sensor as follows:

NOTE: The new bracket will be oriented the same way the old bracket was.
a. Cut the old plastic zip tie with an appropriate tool to remove the fluid temperature

sensor’s metal bracket from the terminal harness assembly (Figure 23 and
Figure 24).

CAUTION: Cut the plastic zip tie over the metal bracket to avoid damage to the
fluid temperature sensor.

b. Discard the removed metal bracket and plastic zip tie.

c. Use the new plastic zip tie from the PARTS INFORMATION on page 32 to attach

the fluid temperature sensor of the terminal connector harness to the fluid
temperature sensor’s new metal bracket.
IMPORTANT:


Locate the plastic zip tie at the center notch of three notches on the fluid
temperature sensor (Figure 24).



Tighten the plastic zip tie so that it is oriented as shown in Figure 23.

d. Cut off the plastic zip tie excess.



For the procedure to fill CVT with NS-3 CVT fluid or equivalent, refer to the ESM,
section TRANSMISSION & DRIVELINE > TRANSAXLE & TRANSMISSION > CVT:
RE0F10D > BASIC INSPECTION > CVT FLUID.
IMPORTANT: For those vehicles that have an external CVT cooler, a cooler flush is
required after a valve body or CVT assembly replacement.
 For the procedure to flush the CVT cooler, refer to the ESM, section
TRANSMISSION & DRIVELINE > TRANSAXLE & TRANSMISSION > CVT:
RE0F10D > BASIC INSPECTION > CVT FLUID COOLER SYSTEM.

TCM Reprogram and Additional Service

The steps starting on the next page must be completed in the following order:

A. TCM Reprogram, if needed.

B. Perform Additional Service
For Transaxle Assembly Replacement


Perform ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE
ASSEMBLY.
 Refer to the ESM, section TRANSMISSION & DRIVELINE - TRANSAXLE &
TRANSMISSION - CVT: RE0F10D - BASIC INSPECTION - ADDITIONAL
SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY.

For Valve Body Replacement:


Perform ADDITIONAL SERVICE WHEN REPLACING CONTROL VALVE.
 Refer to the ESM, section TRANSMISSION & DRIVELINE > TRANSAXLE &
TRANSMISSION > CVT: RE0F10D > BASIC INSPECTION > ADDITIONAL
SERVICE WHEN REPLACING CONTROL VALVE.

C. Confirm DTCs are erased.

D. Confirm that there are no fluid leaks.

TCM Reprogramming
A.

IMPORTANT: Repairs performed for this bulletin require CONSULT-III plus (C-III plus)
Diagnostic result reporting function-Setting to be turned ON and Diagnosis (All Systems) to
be selected. If not done, it may result in a repair being non-warrantable.
IMPORTANT: Before starting, make sure:
 ASIST on the CONSULT PC has been synchronized (updated) to the current date.
 All C-III plus software updates (if any) have been installed.
 The CONSULT PC is connected to the Internet (Wi-Fi or cable).
NOTE:



Most instructions for reprogramming with C-III plus are displayed on the CONSULT
PC screen.
If you are not familiar with the reprogramming procedure, click here. This will link
you to the "CONSULT- III plus (C-III plus) Reprogramming" general procedure.

CAUTION:


Connect a battery maintainer or smart charger set to reflash mode or a similar
setting. If the vehicle battery voltage drops below 12.0V or rises above 15.5V
during reprogramming, the TCM may be damaged.



Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the TCM may be damaged.



Be sure to connect the AC Adapter.
If the CONSULT PC battery voltage drops during reprogramming, the process
will be interrupted and the TCM may be damaged.



Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.)
within range of the CONSULT PC and the VI. If Bluetooth® signal waves are
within range of the CONSULT PC during reprogramming, reprogramming may
be interrupted and the TCM may be damaged.

25. Connect the CONSULT PC to the vehicle to begin the reprogramming procedure.

26. Start C-III plus.

27. Wait for the plus VI to be recognized.


The serial number will display when the plus VI is recognized.

28. Select Re/programming, Configuration.

29. Follow the on-screen instructions and navigate C-III plus to the screen shown in
Figure 33 on the next page.

30. When you get to the screen shown in Figure 33, confirm reprogramming applies as
follows:
A. Find the TCM Part Number and write it on the repair order.
NOTE: This is the current TCM Part Number (P/N).

In some cases, more than one new P/N for reprogramming is available.
 If more than one new P/N is available, the screen in Figure 34 displays.
 Select and use the reprogramming option that does not have the message
“Caution! Use ONLY with NTBXX-XXX”.



If you get this screen and it is blank (no reprogramming listed), it means there is no
reprogramming available for this vehicle.
