SERVICE PROCEDURE

ICC/ADAS Reprogramming

IMPORTANT: Before beginning the following procedure, 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.



The CONSULT PC is connected to the internet via a cable or Wi-Fi.
o Later in the procedure you will be required to enter your username and
password.
o If you do not know your username and password, contact your service
manager.

1.



A screen print for warranty documentation can be done from the CONSULT PC
during this SERVICE PROCEDURE while still connected to the vehicle.



No diagnostic trouble codes (DTCs) are stored.

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

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

Make sure the VI is securely connected. If the VI connection is loose during
reprogramming, the process will be interrupted and the control unit may be damaged.
2.

Connect the AC Adapter to the CONSULT PC.

Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops during
reprogramming, the process will be interrupted and the control unit may be damaged.
3.

Connect a battery maintainer or smart charger set to reflash mode or a similar setting.
To avoid damage to the control unit, ensure a battery maintainer or smart charger is
connected. The battery voltage must be between 12.0V and 13.5V during
reprogramming.

4.

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 and the VI during
reprogramming, reprogramming may be interrupted and the control unit may be
damaged.
