SERVICE PROCEDURE
Confirm the ICC/ADAS 2 Part Number
IMPORTANT: Before starting, make sure:

1.



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



All C-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 15.5V during reprogramming, the ICC/ADAS 2 control unit may be
damaged.



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

Connect the Vehicle Interface (VI) to the vehicle.
