Function requirements, general

Circuit 15R ON

The status of circuit 15 is made available by the electronic ignition lock control unit (N73) to the instrument cluster (A1) on the interior CAN (CAN B).

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 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) read in the control interventions at the multifunction steering wheel button groups directly and send them 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 via the chassis CAN (CAN E) (up to 31.05.2013) or via chassis CAN 1 (CAN E1), the front SAM control unit with fuse and relay module (N10/1) and chassis CAN 2 (CAN E2) (as of 01.06.2013).

The following menus are accessible:

"Vehicle data" menu
"Dynamometer test" menu
"ASSYST PLUS" menu

"Vehicle data" menu

The following data can be called up in the vehicle data menu:

Voltage (in V) and amp draw (in A) in on-board electrical system
Data from instrument cluster (object numbers, version numbers, software releases, supplier data on software, Daimler software version display etc.)
Engine data and vehicle information (engine number, vehicle ident. number (VIN) etc.)

"Dynamometer test" menu

Activation of the dynamometer test prevents errors from being entered in the Electronic Stability Program control unit (N30/4) (up to 31.05.2013 without CODE 233 (DISTRONIC PLUS) or as of 01.06.2013) or in the Premium Electronic Stability Program control unit (N30/7) (up to 31.05.2013 with CODE 233 (DISTRONIC PLUS)) during the brake test on the roller dynamometer.

The following settings can be selected in the dynamometer menu:

"On"
"Off" with circuit 15 OFF

If the workshop menu is left and the menu "Dynamometer test" was not deactivated prior to this, it will be automatically called up during the next ignition cycle.

"ASSYST PLUS" menu

The following data can be called up in the ASSYST PLUS menu:

Service data
Full service
"Vehicle handover" (nonrecurring display prior to handover to customer; if function not performed by dealer, then the display is automatically hidden after s = 250 km)

After completion of the service, the service interval is reset in this menu.
