Service

Update Programming Procedure:

Critical Warning: TheMidtronics battery chargermustbe 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 24.3.2 or higher and SW version 2.52.9 or higher.

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.

To Update-Programming using Software Version Management (SVM), review and follow instructions in Technical Bulletin Instance 2014603 “Software Version Management”.

The SVM process must be completed in its entirety, so the database receives the update confirmation response. A warranty claim may not be reimbursed if there is no confirmation response to support the claim or action is carried out that is not explicitly stated in the Technical Bulletin

Update the 00A5 - Front Sensor for Driver Assistant Systems (MFK) -R242- using the SVM Unit code as listed in the table below:

Model	Engine	Old Software Part No.	Old Software Version	New Software Part No.	New Software Version (or higher)	SVM Unit Code
Atlas	All	5WA980653D	v3403/3405	5WA980653G	v3408	4F79
Atlas Cross Sport	All	5WA980653D	v3403/3405	5WA980653G	v3408	4F79

The procedure can be found in GFF under Functions/ Component Selection, Software Version Management, Adapting Software.

Reactivatethe Lane Assist function in the MFI/MIB menu and road test the vehicle to validate system operation.
