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.

NOTE:

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:
