SERVICE PROCEDURE
LBC (for HV BATTERY 2 and HV BATTERY) Reprogramming
IMPORTANT: Before continuing, make sure:



ASIST on the CONSULT PC has been synchronized (updated) to the current
date.
All CONSULT-III plus (C-III plus) software updates (if any) have been installed.
The CONSULT PC is connected to the Internet (Wi-Fi or cable).
CAUTION: Disconnect the Electric Vehicle Service Equipment (EVSE). Do not
charge the High Voltage (HV) Lithium Ion battery during reprogramming.
NOTE: Check to see if the timer for either charging or climate control is ON. If ON,
turn it OFF and make sure to turn it back on after reprogramming.
CAUTION:

Connect a battery maintainer or smart charger set to reflash mode or a similar
setting. If the vehicle’s battery voltage drops below 12.0V or rises above 15.5V
during reprogramming, the LBC may be damaged.

Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load remains
ON, the LBC 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 LBC may be
damaged.

Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within
range of the CONSULT PC and the plus VI. If Bluetooth® signal waves are within
range of the CONSULT PC and/or the plus VI during reprogramming,
reprogramming may be interrupted and the LBC may be damaged.
DO NOT CHARGE
