IF YOU CONFIRM
The MIL is ON with DTC P0776 (PC SOLENOID B – Pressure Control Solenoid “B”
Performance/Stuck OFF) stored.
NOTE:
If P0744, P0746, P0841, P0965, P2813, or P17F0 are stored this bulletin does not
apply. Refer to ASIST for diagnostic assistance.
With this incident, if it should occur, P1715 (INPUT SPEED SENSOR) may be
stored with DTC P0776. The vehicle may also hesitate and/or have reduced power.
ACTION
1. Refer to the Repair Flow Chart on page 2 for mechanical CVT repair.
2. If needed, reprogram the TCM.
Refer to step 30 in the TCM Reprogramming section (page 21) of the SERVICE
PROCEDURE to confirm if reprogramming is needed.
3. Perform Additional Service (page 19).
IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you
will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it
contains information that is essential to successfully completing this repair.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

6. Using borescope J-51951 with its mirror Pulley
attachment, inspect the entirety of the
Case
two sides of the belt that come in contact
with the pulleys (see page 7, Figure 8).
Reference the Figures on pages 9
through 12 for comparison of an OK
and NG belt condition.
NOTE:
Be sure to remove the protective film Step 6a
Step 6d
from the mirror before the first use.
Clean the camera lens and mirror
before each inspection. Use 90% Figure 3
isopropyl alcohol, and a lens swab
from Lens Swab packet J-51963
listed in the PARTS INFORMATION
on page 32.
Camera
Before inspecting, make sure the flexible tube
camera handle’s AA batteries are
Front
charged and the LCD monitor’s
battery is charged.

b. Slowly and carefully turn the front left
tire one full turn in the forward
rotation to view all of the belt.
Holding the borescope with one
hand allows for turning the tire
with the other hand
(see Figure 5).
CAUTION: If the tire is rotated in the
rearward rotation, the camera lens
may get caught between the belt and
pulley.

f. If CVT replacement is required based
on the inspection results from 6b and
6d, use borescope J-51951 to record VIN
a continuous video, 15 seconds or label
less, of the most severe evidence of
belt slip and the VIN on the
F.M.V.S.S. certification label (VIN
label). See Figure 7.
Figure 7
NOTE: This required video must be attached to the Powertrain Call Center CVT
Preauthorization Form (in ASIST) prior to calling for authorization. Failure to submit
a continuous video will cause immediate denial of request for replacement.
Before starting to record, make sure the camera handle’s AA batteries are
charged and the LCD monitor’s battery is charged.
The video will show a backward or reversed image when the mirror end is used;
this is okay.
The required video must show clear evidence of belt slippage and be 15 seconds
or less.
Do not inspect
these sides

8. Obtain authorization to replace the CVT assembly. See CVT Assembly Replacement
Approval Procedures on page 35.
9. After receiving authorization, replace the CVT assembly, then proceed to page 20 to
reprogram the TCM, and then perform Additional Service when Replacing Transaxle
Assembly. Additional information related to TCM reprogramming is found on page 19.
For CVT assembly replacement, refer to the ESM, section TRANSMISSION &
DRIVELINE > TRANSAXLE & TRANSMISSION > CVT: RE0F10D > UNIT
REMOVAL AND INSTALLATION > TRANSAXLE ASSEMBLY.
IMPORTANT: For those vehicles that have an external CVT cooler, a cooler
flush is required after a valve body or CVT assembly replacement.
o 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.
For the procedure to fill CVT with NS-3 CVT fluid or equivalent, refer to the ESM,

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.
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.

TCM Reprogramming
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.
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.
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.
