  i = diagGetTargetCount();
  while( i-- > 0)
  {
    long class;
    long status;
    if( 0 >= diagGetTargetQualifier( i, ecuQual, elcount( ecuQual)))
    {
      TestStepFail( "", "Cannot retrieve qualifier of ECU target %d", i);
      continue;
    }
    write( "Collecting information from target %s", ecuQual);
    status = TestCollectDiagEcuInformation( ecuQual, "Identification");
    if( status == 0)
