If you are not familiar with the reprogramming procedure, click here. This will link you
to the "CONSULT- III plus (C-III plus) ECM Reprogramming" general procedure.

CAUTION:


Connect a battery maintainer or smart charger to the 12V battery.
If the vehicle battery voltage drops 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 VI. If Bluetooth® signal waves are
within range of the CONSULT PC during reprogramming, reprogramming may
be interrupted and the ECM may be damaged.
