Update-Programming Procedure:

Critical Warning: : The Midtronics battery charger must be connected to the vehicle battery for the

duration of the programming, to ensure the battery state of charge remains above 12.5 volts during the

update process. If the battery drops below 12.5 volts, the programming could fail which may result in

damage to the control module. Control modules damaged by inadequate voltage will not be covered

under the warranty policy.The technician should verify the vehicle voltage prior to starting the update

process, and should monitor the voltage for the duration of the update.

The procedure may cancel itself if the hazard warning lights are not switched ON. The hazard warning

lights prevent the system from switching to bus sleep mode during the update.

ODIS-Service tester should be updated to the latest GFF technical version 10.0.0 or higher and SW

version 2.46.0 or higher.
WARNING:

Radiator Fan(s) may cycle ON high speed during the Update Process! There is a risk that personal

injury may result if contact is made with spinning fan blades.

Keep hands and all objects away from Radiator Fan(s) during Update Process!
Note:

Prior to launching the ODIS Service diagnostic applications and starting control module update process,

confirm tester screen saver and power settings in accordance with Diagnostic Device Hardware &

Windows® - VHW-20-02 Change Power Options After Windows®10 Upgrade. Failure to do so may result

in the tester entering power save mode during data transfer, and subsequent control module failure.

When using a VAS 6150/X or 6160/X tester in conjunction with a VAS 6154 wireless transmitter head for

a flash procedure, connect a USB cable between the transmitter head and the tester. Failure to do so

may lead to errors during the flash procedure.

VAS tools must only be used with their power adapters plugged in. Under no circumstances should they

be used on battery power alone during the programming procedure.
