INTRODUCTION
Infiniti is conducting this voluntary service campaign on certain specific 2013 JX35 and 2014 QX60 vehicles to
reprogram the TCM and, if needed, inspect and replace the CVT or CVT control valve. This service will be
performed at no charge to the customer for parts or labor.
IDENTIFICATION NUMBER
Infiniti has assigned identification number PC501 to this campaign. This number must appear on all
communications and documentation of any nature dealing with this campaign.
DEALER RESPONSIBILITY
Dealers are to repair vehicles falling within range of this campaign that enter the service department. This
includes vehicles purchased from private parties, vehicles presented by transient (tourists) owners, and
vehicles in a dealer’s inventory.
Infiniti 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 Infiniti retailer to determine if this
applies to your vehicle.

TCM REPROGRAMMING
NOTE: If DTC P17F0 or P17F1 was stored, reprogramming is not needed.
IMPORTANT: Before starting, make sure:

ASIST on the CONSULT PC has been synchronized to the current date.

All CONSULT related software updates (if any) have been installed.
NOTE:

Some vehicles affected by this campaign may already have the specified reprogramming. In step 6
of the reprograming procedure you will determine if reprograming is needed.

Most instructions for reprogramming with CONSULT-III plus (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 Reprogramming" general procedure.
CAUTION:

Connect the GR8 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.

CVT CHAIN INSPECTION / CONTROL VALVE (VALVE BODY) REMOVAL
IMPORTANT: This part of the Service Procedure is performed only if both of the following apply:

The customer answers Yes to the Service Advisor Interview (see page 3), and

DTC P07F1 is stored.
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 Electronic Service Manual (ESM), section TM-Transmission, for valve body removal.
NOTE:
o The CVT unit harness connector may be left in place when removing the valve body assembly.
o The number “7” is on the head of all valve body bolts that need to be removed. 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.
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 1C
16/53
ITB16-048
4. Using borescope J-51951 with mirror attachment, visually inspect the side of the CVT chain that comes in
contact with the pulley:
NOTE: It is recommended that you review the instructions and Figures on pages 17 through 23 before
continuing with the procedure.
a. Insert the borescope into the correct area of the CVT (see Figures 4C - 7C).
b. Slowly and carefully turn the left front tire one full turn in the forward rotation to view all of the chain.
CAUTION: If the tire is rotated in the rearward rotation, the camera lens may get caught between
the chain and pulley.

Holding the borescope with one hand allows for turning the tire with the other hand (see Figure
2C).
Figure 2C
NOTE: Reference the photos on pages 22 – 24 for examples of chain slippage and for
comparison to the vehicle you are working on.

First inspect the entirety (360°) of the driver side of the chain that comes in contact with the pulley
(see pages 19 – 20).

If the inspection result is OK on all 360° of driver side of the chain; inspect all 360° of the
passenger side of the chain.
17/53
ITB16-048
 If no evidence of chain slippage is found on both sides of the chain; go to VALVE BODY
REPLACEMENT on page 26.
 If any evidence of chain slippage is found, go to step 5 below.
5. Evidence of chain slippage was found:
a. Create video of the chain slip/damage and the VIN for PCC (Powertrain Call Center) CVT replacement
authorization.


Use borescope J-51951 to record a 15
second or less continuous video of the
most severe evidence of chain
slip/damage and the VIN on the
F.M.V.S.S. certification label (VIN label).
Example
of VIN label
location
For best picture, the camera lens should
be about 10 mm away from the object
being recorded.
Figure 3C
b. The CVT unit requiring replacement will need to be reassembled (valve body reinstalled) for Infiniti
parts return/collection.
c. Go to CVT ASSEMBLY REPLACEMENT on page 25.
NOTE:

The 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.

Refer to Figures 4C to 8C for camera lens (borescope) insertion instructions:

Insert the camera lens behind the pulley between the guide rail and the pulley where shown in
Figure 4C (see also Figure 5C – 8C).

Insert approximately 8-9 inches, and then view the side of the chain that contacts the pulley.

POWERTRAIN CALL CENTER (PCC) AUTHORIZATION
CVT Assembly Replacement Approval Procedures

If P17F0 is stored for CVT replacement:
a. Complete the Powertrain Call Center (PCC) CVT Preauthorization Form in ASIST.
b. Attach the C-III plus screen printouts showing the VIN and DTC to the Preauthorization Form.
c. Call the PCC for authorization at 800-973-9992 (opt 2).

If P17F1 is stored and CVT chain inspection indicates CVT assembly replacement is required:
a. Complete the PCC CVT Preauthorization Form in ASIST.
b. Attach the C-III plus screen printouts showing the VIN and DTC to the Preauthorization Form.
c. Attach the required video (15 seconds or less) to the CVT Preauthorization Form.

Failure to submit a continuous video showing evidence of chain slip and the VIN will cause
immediate denial of request for CVT unit replacement.
d. Call the PCC for authorization at 800-973-9992 (opt 2).
IMPORTANT: Make sure the video has a clear image of the VIN on the F.M.V.S.S. certification label
(VIN label).
