ACTION
1. Save Computer Data with CONSULT-III plus (C-III plus).
2. At step 6 of the ECM Reprogramming procedure, confirm this bulletin applies to the
vehicle you are working on (see page 7).
3. If this bulletin applies, continue with ECM Reprogramming procedure.
4. Write Saved Data with CONSULT-III plus.
5. Perform DTC Confirmation procedure.
NOTE: The vehicle will need to sit for 70 minutes with the ignition ON during this
procedure.
IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you
will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it
contains information that is essential to successfully completing this repair.
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.

ECM Reprogramming

NOTE:


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 (C-III plus) Reprogramming" general procedure.



For the Titan XD Diesel, the GR8 set to ECM power supply mode can be attached to
either 12 volt battery.

CAUTION:


Connect the GR8 to the 12V battery and set to ECM power supply mode.
If the vehicle battery voltage goes below 12.0V or above 15.5V during
reprogramming, the ECM may be damaged.



Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the ECM 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 ECM may be damaged.



Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.)
within range of the CONSULT PC and the plus VI. If Bluetooth® signal waves
are within range of the CONSULT PC during reprogramming, reprogramming
may be interrupted and the ECM may be damaged.
