CVT / TCM CALIBRATION DATA “WRITE” PROCEDURE
This bulletin has been amended. APPLIED VEHICLES has been updated. SERVICE INFORMATION
has been amended. A REPAIR TABLE has been added. Procedural steps have been added to
SERVICE PROCEDURE. Discard all previous versions of this bulletin.

APPLIED VEHICLES: 2013 – 2017 Altima Sedan (L33)
2013 – 2017 Pathfinder (R52)
2015 – 2017 Murano (Z52)
2015 – 2017 Quest (E52)
2014 – 2017 Rogue (T32)
2016 – 2017 Maxima (A36)
2015 – 2017 Juke (F15)
NOTE: Does not apply to Pathfinder Hybrid, Murano Hybrid, or Rogue Hybrid.

SERVICE INFORMATION
The Service Procedure (starting on page 2) in this bulletin contains the steps to perform
TCM Calibration Data “Write” Procedures. These procedures are used when a complete
CVT assembly is replaced, a CVT control valve (valve body) is replaced, or a Transmission
Control Module (TCM) is replaced.


Refer to REPAIR OVERVIEW on page 2. This is a quick reference to determine
which procedures need to be performed.

NOTE: The following information may be helpful when performing the TCM Calibration
Data “Write” Procedures:
 When starting the calibration “write” procedure in CONSULT-III (C-III) plus, and after
selecting START under Work Support, the C-III plus screen may only blink.
If this occurs, close ASIST (if open), and then select Start again.
 If there is still no change: reboot the CONSULT PC, keep ASIST closed, and
then restart this procedure from step 1.
 If error “STOPPED, no comm. with ECU” shows when trying to write calibration
data, verify that the vehicle is in Park (P).

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.
