Commissioning

The service function 'Commissioning' must be run after:

• A component replacement (repair instructions, diagnosis)
  
• Coding or program the Dynamic Drive control unit
  
• Learning parameters and zero point for new sensors
  
• Opening the hydraulic system (e.g. venting).
  

The service function 'Start commissioning' contains the following functions:

• Learn sensor system parameters
  
• Learn sensor system zero point
  
• Self-test of the Dynamic Drive System
  

Learning the parameters and zero point passes on important values of the new sensors to the Dynamic Drive control unit. These values are needed by the control unit as the basis for internal calculations. If these values are not learned correctly, the entire system accuracy of the Dynamic Drive is endangered. Commissioning the Dynamic Drive cannot be continued.

The self-test of the Dynamic Drive System is divided into five phases:

• Test of the direction valve
  
• Low pressure test of the pressure control valves
  
• High pressure test, front axle
  
• High pressure test, rear axle (Caution: vehicle rolls!)
  
• Test of pressure pre-control
  

If a fault is detected during commissioning, the commissioning sequence is cancelled immediately and a fault code memory entry is made. In order to be able to ensure correct system function, the commissioning must be run in full. In addition, the entire fault code memory of the Dynamic Drive system must be blank.

Requirements for the service function 'Start commissioning'

Before starting commissioning, set up the following vehicle condition:

• Comply with the instructions of the diagnosis (first ignition on, then let the engine run at idle speed...)
  
• Oil temperature of the Dynamic Drive system must lie between 50 degrees Celsius and 70 degrees Celsius.
  
• The vehicle is horizontal with all wheels on a firm base
  
• No vibrations on the vehicle
  
• Doors of the vehicle are closed
  

Safety regulations for commissioning

Important: During commissioning, the vehicle is subject to strong rolling motion. Disregarding the following instructions could put lives at risk!

• No persons directly at the vehicle, especially not near moving driveline parts
  
• No objects underneath the vehicle or in the wheel arches
  
• Under no circumstances may the commissioning procedure be carried out with the vehicle on a lifting ramp, suspension alignment tester, shock absorber tester or similar apparatus.
  

Learning parameters and zero point

The service functions 'Learn parameters and zero point of the sensors' have to be run after:

• Replacement of the transverse acceleration sensor
  

The service functions 'Learn parameters and zero point of the sensors' are integrated in the 'Commissioning' sequence.

Requirements for the service functions 'Learn parameters and zero point of the sensors'

Before starting the learning parameters and/or zero point tasks, the following vehicle condition must be set up:

• Engine off, ignition on
  
• The vehicle is horizontal with all wheels on a firm base
  
• No vibrations on the vehicle
  
• Doors of the vehicle are closed
