Update-Programming Procedure

Tip:

To Update-Programming using 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.

NOTE: Prior to launching VAS-PC application and starting control module update process, confirm tester screen saver and power settings in accordance with Special Tools and Equipment - Service Information Circular # VSE-08-18. 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 6150/5051B or VAS 5052A tester in conjunction with a VAS 5054A wireless transmitter head for a flash procedure, please connect a USB cable between the transmitter head and the tester. Failure to do so may lead to errors during the flash procedure.

Update the Engine Control Module 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
EOS CC	2.0T (CBFA)	06J 906 027AA	5769 6089 6453	06J 906 027AA	965	3642
		06J 906 027CH	1121 0808 0774	06J 906 027CH	1440	3642
		06J 906 027AR	8909 8073 7488 7202	06J 906 027CH	1440	3642
		06J 906 027AC	5616 6088 6452	06J 906 027AC	9655	3642
		06J 906 027G	8072 7486 7201	06J 906 027CK	0894	3642

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

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!
