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.
HINT: 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.
o If there is still no change: reboot the CONSULT PC, keep ASIST closed, and then restart this
procedure from step 6 on page 5.
o If the error “STOPPED, no comm. with ECU” shows when trying to write calibration data, verify that
the vehicle is in park (P).
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.

ERASE/WRITE CALIBRATION DATA WHEN REPLACING CVT OR VALVE BODY
HINT:

Use the following steps when a CVT assembly or valve body is replaced.

Also use the following steps if the TCM was replaced with a CVT assembly or valve body.
Before starting, make sure:



All C-III plus software updates (if any) have been installed.
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.
