Workshop level adjustments, general 

The workshop level is used by technicians in the workshop for reading out vehicle and service data and provides assistance with carrying out the service.

The "Workshop level" menu is activated as follows:

• Select "Trip" menu.
• Press right button of accept and end phone call button (S111s3) in right multifunction steering wheel button group (S111) and OK button (S110s6) in left multifunction steering wheel button group (S110) simultaneously for t > 3 s.

The display in the multifunction display (A1p13) changes to the workshop level. It is possible to scroll between the respective menus and submenus or through the different lists by pressing the scroll forward/back button (S110s1). Selection is then made by pressing the OK button.

The steering wheel electronics (N135) read in the control signals from the multifunction steering wheel button group directly and sends them via the steering LIN (LIN E1) to the steering column tube module control unit (N80). The steering column tube module control unit sends the control signals for the multifunction steering wheel button groups over chassis CAN 1 (CAN E1), the electronic ignition lock control unit and chassis CAN 2 to the instrument cluster.

The following menus are accessible:

• "Vehicle data" menu 
• "Dynamometer test" menu 
• "Change brake lining" menu 
• "ASSYST PLUS" menu 

"Vehicle data" menu
