Diagnosis

Project description

Diagnosis within the framework of maintenance and software development (time estimation and programming of extensions) as well as testing of various functions.

Objective/customer benefit

• Reduction in error frequency


• Management of errors which occur in order to lead to recognition, handling and documentation of a problem

Solution

• Adjustment parameter (coding, adjustment channels)
  Reading and writing of coding and adjustment channels. In this way the software is adapted to a specific vehicle.


• Readout of various measured data


• Error memory (diagnostic trouble code, DTC for short)
  Recording, reading and deleting of problems which occur under certain conditions.


• Component protection
  Training of a headunit - process where the headunit is calibrated exactly to a specific vehicle. Blocking of the headunit in the case of improper use.


• Ring break diagnosis


• Reading and writing of individual memory cells in EEPROM


• Analysis of any malfunctions occurring
  • Identification if the error is caused by operating error or other control device
  
  
  • Analysis of MOST/CAN traces (communication and interaction of the control devices involved), IRC logs, error memory entries and source code
  
  
  • Carrying out of tests to reproduce the malfunction
  
  
  • Simulation and analysis
