It says always Initializing, then CAN-LS Error unknown CEM Exiting... no matter if car is closed locked, or open, or Key is in position I or II

Remove CEM_PN_AUTODETECT and set those to what your car has:

#else
  can_ls_init (CAN_125KBPS);
  can_hs_init (CAN_500KBPS);
  progModeOn ();
  pn = ecu_read_part_number_prog (CAN_HS, CEM_HS_ECU_ID);
#endif

2004 P2 is a CEM-B. It never will get a response unless your cracker has a K-line OR you tap into the network some place other then the OBD connector.
