Settings on workshop level, function - GF54.30-P-2020LE

MODEL 216.3, 221.0/1 as of model year 2009/YoM 08 

Function requirements, general 

• Circuit 15R ON

The EZS control unit (N73) places the status of circuit 15 on the chassis CAN (CAN E). The central gateway control unit (N93) forwards this to the instrument cluster (A1) via the central CAN (CAN F).

Function sequence for workshop level settings in 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 in start menu display
• Press accept and end phone call button (S111s3) and OK button (S110s6) simultaneously for t > 1 s

The display in the multifunction display (A1p13) changes to the workshop level. (S110) It is possible to scroll between the respective menus and submenus or in various lists using the left multifunction steering wheel button group.

The steering column tube module (N80) reads in the selection via the steering LIN (LIN E1) and transmits it on the interior CAN (CAN B). The central gateway control unit passes these on to the instrument cluster via the central CAN.

The following menus are accessible:

• "Vehicle data" menu 
• "Dynamometer test" menu 
• "Active Service System PLUS workshop" menu 

"Vehicle data" menu 

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

• Voltage "U" in V and current consumption "I" in A in on-board electrical system
• Data from instrument cluster (e.g. version numbers, software releases)
• Engine data (e.g. engine number)
• Oil data (e.g. filling capacity, temperature)
• Vehicle data (e.g. chassis number)
• AdBlue® (tank full/tank not full)
• High-voltage voltage status (on model 221.095/195) (de-energized/not de-energized)

High-voltage system status indication (on model 221.095/195) 

Display for:

• Circuit 15R ON
  • Irrespective of status of interlock circuit
• Circuit 15 ON
  • Successful high-voltage system power disconnect
  • Open interlock circuit (fault)

High-voltage system status indication (on model 221.095/195) 

Display for:

• Circuit 15R ON
  • Fault in high-voltage system
• Circuit 15 ON
  • High-voltage system operational (no fault)
  • Unsuccessful high-voltage system power disconnect

"Dynamometer test" menu 

Activation of the dynamometer test prevents faults from being entered in the ESP control unit (N47-5) (except model 221.095/195) or in the regenerative braking system control unit (N30/6) (on model 221.095/195) during the brake test on the roller dynamometer. It is possible to switch between the following settings in the roller dynamometer mode submenu using the left multifunction steering wheel button group:

• "On"
• "with circuit 15 OFF"

When the Workshop level menu is exited and, if the dynamometer test mode was not deactivated beforehand, the Dynamometer test mode menu is automatically called up the next time the ignition sequence is initiated.
