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.

column in Table A below.


If there is a match, continue with the reprogramming procedure.



If there is no match, this bulletin does not apply. Close C-III plus and refer to
ASIST for further diagnostic information.

 Select and use the reprogramming option that does not have the message
“Caution! Use ONLY with NTBXX-XXX”.



If you get this screen and it is blank (no reprogramming listed), it means there is no
