IMPORTANT: Before starting, make sure:

ASIST on the CONSULT PC has been synchronized (updated) to the current
date.

All C-III plus software updates (if any) have been installed.

Connect a battery maintainer or smart charger set to reflash mode or a similar
setting. If the vehicle battery voltage drops below 12.0V or rises above 15.5V
during reprogramming, the TCM may be damaged.

Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the TCM 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 TCM 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 or VI during reprogramming, reprogramming
may be interrupted and the TCM may be damaged.
NOTE: The following steps are to be performed after the TCM has been replaced.
