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.

3. Turn ON the CONSULT PC, and then open CONSULT III plus (C-III plus).
NOTE: Make sure all applications other than C-III plus are closed.
4. Press the ignition switch twice without depressing the brake pedal.

The meter and gauges will illuminate.

Do Not start the engine.

Make sure ALL accessories are turned OFF.
5. Wait for the plus VI to be recognized.

The serial number will display when the plus VI is recognized.
6. Go to Diagnosis (All Systems).

Control Valve (Valve Body) Removal and CVT Chain Inspection –for DTC P17F1
ONLY
1. Remove the valve body.

Before lifting the vehicle:
 Place the transmission gear selector in Neutral.
 Leave the driver door unlatched. A step further in the procedure may require it.
NOTE:
o The number ‘7’ is on the head of all bolts that need to be removed for valve
body removal. Do not remove any bolt that does not have the number ‘7’.
o Due to multiple model vehicles, pictures throughout the service procedure are
examples and may not exactly match your vehicle.
CAUTION: Never allow any chemicals or fluids other than NS-3 CVT fluid or
equivalent to enter the CVT assembly. Never allow any foreign debris, dust,
dirt, etc. to enter the CVT assembly.
NOTE: For additional information, see video # 546: “CVT Chain Inspection”. This
video is located under the TECH TRAINING GARAGE VIDEOS tab in Virtual
Academy.

2. Secure the right front tire with a suitable strap.

This will assist in making the chain turn.
3. Mark the left front tire with a suitable marking.

This will assure all 360° of the chain is
inspected.
Figure 5
4. Using borescope J-51951 with mirror attachment, visually inspect the side of the chain
that comes in contact with the pulley:
a. First inspect the entirety (360°) of the driver side of the chain that comes in contact
with the pulley (see page 10, Figure 9 and 10, and page 12, Figure 13).
b. If the inspection result is OK on all 360°, inspect all 360° of the passenger side of the
chain.
NOTE: Reference the pictures on page 13-15 for comparison.

Insert the camera lens behind the pulley between the guide rail and the pulley
where shown in Figure 6 (also see page 9-10, Figure 7-10).

Insert the lens approximately 8-9 inches, and then view the side of the chain that
contacts the pulley.

4c. Slowly and carefully turn the left front
tire one full turn in the forward rotation
to view all of the chain.

Holding the borescope with one
hand allows for turning the tire with
the other hand (see Figure 11).
CAUTION: If the tire is rotated in the
rearward rotation, the camera lens
may get caught between the chain
and pulley.
d. If the inspection result is OK on all
360° on both sides of the chain, skip
to step 5 on the next page.

If any evidence of chain slippage
is found, go to step 4e, and then
skip to step 6.

Refer to Garage Video #564 if
needed (see bottom of page 7).
Figure 11
e. Once CVT replacement is determined
as required, use borescope J-51951 to
record a 15 second or less continuous
video of the most severe evidence of
chain slip and the VIN on the
F.M.V.S.S. certification label (VIN
label). See example in Figure 12.

Example

For best picture, the camera lens
should be about 10 mm away from

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 fresh and
the LCD monitor’s battery is charged.
The whole video will show as backward, or reversed mirror image. This is okay.
The required video must show clear evidence of chain slippage and be 15 seconds
or less.

5. Flush the CVT cooler(s).
IMPORTANT: A CVT Cooler flush is required after a valve body or CVT assembly
replacement. Refer to bulletin NTB15-013 to perform CVT Cooler flush.
6. If the chain inspection result is OK, replace the valve body.


There is no need for pictures or video showing “OK” chain surfaces.
For valve body replacement, go to page 16, Control Valve (Valve Body)
Installation.
7. If the chain inspection result is NG, replace the CVT assembly.



Get authorization to replace the CVT assembly (see page 25).
Make sure to perform step 4d on page 11.
For CVT assembly replacement, refer to the appropriate ESM, section TM –
Transaxle & Transmission.
IMPORTANT: Perform "ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE
ASSEMBLY".
 Refer to TM – Transaxle & Transmission / BASIC INSPECTION:
o Check for fluid leakage.
o Install Write IP Characteristics to the TCM.
o Perform Select Learning (Drive/Reverse Learning)
o Erase CVT Fluid Degradation Level Data

The CVT unit requiring replacement will need to be reassembled for Nissan parts
return/collection.
