Electronic System Specific Information

• Trouble Code Features
  In a few cases, the diagnostic tester may display a trouble code status or description that looks unfamiliar:
  
  Trouble Code Status:
  Instead of the known PRESENT, NOT PRESENT (and INTERMITTENT) message, you may read UNKNOWN DTC in the tester display. This tells you that the diagnostic software or control unit contains a piece of incorrect information that is unknown to the diagnostic tester and that it is unable to read or evaluate. Both the trouble code number and the trouble code text are not changed in this case.
  
  The above mentioned special cases can not be removed by means of a diagnostic tester function.
• Data List Parameter
  Depending on the vehicle/system configuration it is possible that some data list parameters or test steps, although they are listed in this checking procedure, are not shown on the diagnostic tester display. In that case, these data list parameters are not valid for this vehicle/system configuration.
• Mechanical and/or Hydraulic Check
  Before repairing the automatic transmission, always run a test using the diagnostic tester in conformity with the requisite Checking Procedures applicable for the relevant transmission.
  The repair and overhauling procedures of the mechanical and hydraulic assembly groups of the automatic transmission are described in detail in the service instructions.
  If remnants of clutch linings, metal shavings, contamination or deposits are detected during transmission repair work, the transmission must be completely disassembled and carefully cleaned with cleaning fluid. All parts and fluid ducts must be blown out and dried with compressed air.
• Measured stall speed
  Always test the stall speed in AT vehicles. During the test, high drive forces are kept under control exclusively by the vehicle's brake system. This test may not be performed for longer than a few seconds or otherwise the automatic transmission will overheat. Place brake wedges in front of and behind the drive wheels to secure the vehicle against rolling. Have a second person monitor the wheels and brake wedges during the test.
• Park Brake Shift Lock
  Now all models with automatic transmissions are additionally equipped with a park brake shift lock.
  The park brake shift lock only allows the movement from selector lever position "P" if the ignition is switched ON and the brake pedal is actuated at the same time. This ensures that the vehicle does not drive off unintentionally.
  In addition, the ignition lock provides a locking mechanism which only releases the ignition key in selector lever position "P".
• Service
  The park brake shift lock operates electro-mechanically. In case of power supply problems or electrical malfunctions the park brake shift lock can be unlocked manually. The procedure is described in the owners manual.
• Service-Programming SPS
  The new FLASH-Programming makes it possible to cover different software variants with one hardware version of a control unit. Depending on the system calibration values, curves and mappings can be programmed into a specific control unit type.
  In order to program those specific vehicle data into the control unit, you need a diagnostic tester and a TIS (TECH Information-System) unit. Up to now, that could only be done by replacing the program memory (EPROM) or even the complete control unit.
  The newest programming data is published with the TIS CD.
  Programming Procedure:
  Connect the diagnostic tester to the vehicle diagnostic connector.
  Start the SPS service programming application.
  Download vehicle data and security access from control unit to diagnostic tester.
  Connect diagnostic tester to TIS.
  Upload vehicle data and security access from diagnostic tester to TECH Information-System (TIS) .
  TIS checks the security access and compares the vehicle data with the data stored on the TIS CD.
  If the security check fails, TIS cannot automatically select the relevant programming data. In case of a failure, TIS requests all information (e.g. vehicle identification number, system name) required in order to select the appropriate system software. For further information please refer to the SPS manual.
  If the security check is passed, the data selected by TIS will be copied from the CD to the diagnostic tester.
  Connect the diagnostic tester with the required program copy to the vehicle.
  The program download to the control unit is executed.
  The SPS service programming procedure is completed, the diagnostic tester recognises whether the data has been properly transferred or not.
  The diagnostic tester is the interface between the storage device TIS and the control unit to be programmed. A direct connection between TIS and control unit is not possible.
  The diagnostic tester is the interface between the storage device (TIS with latest TIS-CD) and the control unit to be programmed. A direct connection between TIS and control unit is not possible.
  Note:
  After service programming the control unit must be labelled with the current calibration identifier.
