Control Valve (Valve Body) Removal and CVT Belt 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.



Refer to the applicable ESM, section TM – Transaxle & Transmission / RE0F10D,
for valve body removal.

NOTE: 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’.

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.


For additional information, see video # 544: “CVT Belt Inspection”. This video is
located under the TECH TRAINING GARAGE VIDEOS tab in Virtual Academy.

2. Secure the front right tire with a suitable
strap.


This will assist in making the belt turn.

3. Mark the front left tire with a suitable
marking.


This will assure all 360° of the belt is
inspected.

Figure 5

4. Using borescope J-51951 with mirror
attachment, inspect the entirety of the two
sides of the belt that come in contact with
the pulleys (see page 10, Figure 11).
Reference the pictures on pages 10
through 14 for comparison.

NOTE:
 Be sure to remove the protective film
from the mirror before the first use.




Step 4a

Clean the camera lens and mirror
before each inspection. Use 90%
isopropyl alcohol, and a lens swab
from Lens Swab packet J-51963 listed
in PARTS INFORMATION.

Step 4c

Figure 6

Before inspecting, make sure the
camera handle’s AA batteries are
fresh and the LCD monitor’s battery
is charged.

Camera
flexible tube
Front

a. Insert the camera lens between the
CVT case and pulley where shown in
Figure 6 and 7.


Insert the lens approximately seven
(7) inches, and then view the side
of the belt that contacts the pulley.
Figure 7

NTB15-084c

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 8).
CAUTION: If the tire is rotated in the
rearward rotation, the camera lens
may get caught between the belt and
pulley.
c. If the inspection result is OK, inspect
the other side of the belt.


Figure 8

Insert the camera lens in the
second location where shown
in Figure 6 and 9, and then
perform step 4b again.

d. If the inspection result is OK 360° on
both sides of the belt, skip to step 5 on
the next page.


If any evidence of belt slippage
is found, go to step 4e, and then
step 6.



For additional information, see
video # 544: “CVT Belt Inspection”.
This video is located under the
TECH TRAINING GARAGE
VIDEOS tab in Virtual Academy.

e. Once it is determined that CVT
replacement is required, use
borescope J-51951 to record a 15
second or less continuous video of the
most severe evidence of belt slip and
the VIN on the F.M.V.S.S. certification
label (VIN label). See Figure 10.
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 belt slippage and be 15 seconds or
less.

5. If the belt inspection result is OK, replace the valve body.



There is no need for pictures or video showing “OK” belt surfaces.
For valve body replacement, go to page 15, Control Valve (Valve Body)
Installation.

6. If the belt inspection result is NG, replace the CVT assembly.




Get authorization to replace the CVT assembly (see page 23).
Make sure to perform step 4e on page 9.
For CVT assembly replacement, refer to the appropriate ESM, section TM –
Transaxle & Transmission / RE0F10D.
IMPORTANT: Perform "ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE
ASSEMBLY".
 Refer to TM – Transaxle & Transmission / RE0F10D / BASIC INSPECTION:
o Check for fluid leakage.
o Install Write IP Characteristics to the TCM; see NTB12-103.



The CVT unit requiring replacement will need to be reassembled for Nissan parts
return/collection.

7. 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.
