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.

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.

SERVICE PROCEDURE
IMPORTANT: If replacing the TCM only, skip to SAVE/WRITE CALIBRATION DATA
WHEN REPLACING THE TCM on page 14.

ERASE/WRITE CALIBRATION DATA WHEN REPLACING CVT OR VALVE BODY
HINT:


Use the following steps when a complete CVT assembly or valve body is replaced.



Also use the following steps if the TCM was replaced with a complete CVT or valve
body.

Before starting, make sure:


ASIST on the CONSULT PC has been freshly synchronized to the current date.

1. Obtain the calibration file disc (provided with the new CVT or valve body).


If a calibration file disc is available, continue to step 2, below.



If a calibration file disc is not available or was damaged, skip to OBTAINING A
CALIBRATION FILE WHEN CD IS UNAVAILABLE on page 21.

2. Match the numbers on the disc with the new CVT or new valve body and QR label.


See pages 3 and 4 for number matching examples.
