Workshop level adjustments, general

The workshop level is used by the technician 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 and hold right button of accept and end phone call button (S111s3) in right multifunction steering wheel button group (S111) press OK button (S110s6) in left multifunction steering wheel button group (S110) within t = 1 s. Then keep both buttons pressed 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) directly reads in the control signals from the multifunction steering wheel button group and sends these via the steering LIN (LIN E1) to the steering column tube module control unit (N80). The steering column tube module control unit sends them to the instrument cluster as of 01.03.2016 via chassis CAN 1 (CAN E1), front SAM control unit with fuse and relay module (N10/1) and chassis CAN 2 (CAN E2) and up to 29.02.2016 via the chassis

CAN.
