^
The vehicle's battery voltage is called "CHARGER INPUT".
^
This is to confirm CONSULT-II is receiving voltage from the vehicle battery.
6.
Turn the vehicle's ignition switch "OFF" and CONSULT-II "OFF".
7.
Remove the Diagnostics Card (red/white) and install the "QR25 Campaign ECM Software" reprogramming card (Orange 16MB) into slot A of
CONSULT-II (see Figure C3).
8.
Connect a battery charger (or a "known good" additional 12V battery) to the vehicle battery (see Figure C4).
^
You MUST Trickle charge the battery during the reprogramming procedure.
^
This is to make sure the battery voltage does not drop below 12.0 volts.
^
DO NOT boost charge the battery during reprogramming.
^
It is normal for the radiator fans to come on during this reprogramming procedure.
^
DO NOT DISCONNECT ANY ELECTRICAL CONNECTIONS TO THE RADIATOR FANS.
CAUTION:
Do not allow the vehicles battery voltage to drop below 12.0 volts during ECU Reprogramming. Permanent ECU damage can occur if
the battery does not maintain the minimum voltage during the ECU Reprogramming.
