5. After the software update has been performed, confirm the "Abort (cancel) documentation" selection. The MMI 3G system will restart. Then
perform the feedback documentation.
Perform feedback documentation using SVM:
1. Follow all instructions in the attached TSB 2011732 00 Software Version Management (SVM), operating instructions.
2. Confirm any proposed parameter settings and coding.
3. Perform test program "5F - Information electronics, resetting fault memory" to clear any faults in the system.
Tip: No control unit is flashed as part of the feedback documentation to the SVM. Do not perform any updates of control units. Do not replace any
control units.
