Control Valve (Valve Body) Strainer and Pan Installation

IMPORTANT: This section may contain different style parts than what were originally installed in the CVT. Pay
careful attention, REASSEMBLY MAY NOT BE IDENTICAL TO DISASSEMBLY.
Confirm that the QR label, control valve and CD part numbers all match before installing the control
valve.
CAUTION: Handle the valve body carefully.

1. Discard the oil strainer bracket (Figure 25).

terminal harness assembly. (Figure 30).

CAUTION: Cut the plastic zip tie over the metal bracket to avoid damage to the temperature sensor.
b. Discard the removed bracket and plastic zip tie.
c. Use the plastic zip tie from Parts Information to attach the new temperature sensor bracket to the

temperature sensor of the terminal connector harness.

Refer to the ESM, section TM – Transaxle & Transmission for CVT fluid filling.

15. IMPORTANT: Install Write IP Characteristics to the TCM; see ITB13-055.


Refer to TM – Transaxle & Transmission / BASIC INSPECTION, and perform ADDITIONAL
SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY.
 Check for fluid leakage.
 Attach the QR label with the new calibration data onto the transmission range switch (inhibitor
switch).

TCM Reprogramming
IMPORTANT: Before starting, make sure:


ASIST on the CONSULT PC has been synchronized (updated) to the current date.



All CONSULT-III plus (C-III plus) software updates (if any) have been installed.

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 to the vehicle battery, set to “power supply” mode.
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.

1. Connect the CONSULT PC to the vehicle to begin the reprogramming procedure.
2. Start C-III plus.
3. Wait for the plus VI to be recognized.


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

4. Select Re/programming, Configuration.

Plus VI is
recognized

5. Follow the on-screen instructions and navigate the C-III plus to the screen shown in Figure 39.
6. When you get to the screen shown in Figure 39, 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).

B. Compare the P/N you wrote down to the numbers in the Current TCM Part Number column in
Table A below.
 If there is a match, continue with the reprogramming procedure; step 7.
 If there is not a match, reprogramming is not needed; skip to step 16 on page 28, Perform
ADDITIONAL SERVICE WHEN REPLACING CONTROL VALVE.

7. Follow the on-screen instructions to navigate C-III plus and reprogram the TCM.
NOTE:


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 40 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. Close C-III plus and refer back to ASIST for further diagnosis.



Before reprogramming will start, you will be required to enter your User Name and Password.
 The CONSULT PC must be connected to the Internet (Wi-Fi or cable).
 If you do not know your User Name and Password, contact your Service Manager.

8. When the screen in Figure 42 displays, reprogramming is complete.
NOTE: If the screen in Figure 42 does not display (indicating that reprogramming did
not complete), refer to the information on the next page.
9. Disconnect the battery charger from the vehicle.

10. Select Next.

NOTE:


In the next step (page 27) you will perform Erase All DTCs.
