Note:
Do not flash a vehicle while it is on the lift. The vehicle must be on the ground, on a level surface.
1. Check the software part number and software level in the level control system control module (J197).
2. Prior to beginning the SVM process, insert a USB memory stick into the VAS 5051B or 5052 tester to capture
the diagnostic log electronically. In case TAC support is required, attach the diagnostic log to the ticket. TAC
will need this log to assist you.
3. Record the coding of the level control system control module (J197).
4. Update the level control system control module (J197) using the SVM action code as listed in the table
below, if necessary.
Note:
Do not use a 6017 or 6017A while flashing. Doing so may result in complete control module failure.
Tip: The SVM Process must be completed in its entirety so that the database receives the update
confirmation response. A warranty claim may not be reimbursed if there is no confirmation response to
support the claim.
For further SVM update instructions and troubleshooting, please refer to TSB 2011732: 00 Software Version
Management (SVM), operating instructions.
