SERVICE PROCEDURE

Reprogram the ICC/ADAS 2
IMPORTANT: Before starting, make sure:

1.



ASIST on the CONSULT PC has been synchronized (updated) to the current date.



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



During the reprogramming process, you will receive some errors. These errors are
expected. Please follow all of the steps in this procedure to successfully complete
the reprogramming process.



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 13.5V
during reprogramming, the ICC/ADAS 2 control module may be damaged.



Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load remains
ON, the ICC/ADAS 2 control module 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 ICC/ADAS 2 control
module 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 ICC/ADAS 2 control module may be damaged.

Connect the Vehicle Interface (VI) to the vehicle.


Make sure to use the correct VI for the CONSULT PC.

2.

Turn the ignition ON with the engine OFF.

3.

Turn ON the hazard warning lamps.

4.

Start C-III plus.

5.

If prompted, select USA/CANADA Dealers from the drop down menu, and then
select OK.

6.

Login using your NNAnet credentials.
IMPORTANT: If not prompted to enter your username and password, the CONSULT
PC may not be connected to Wi-Fi. Close C-III plus, confirm the CONSULT PC is
connected to Wi-Fi, and then reopen C-III plus.
