ROM

ECM is installed on the lower side of the engine room.
ECM judges (calculates) the optimum control to deal
with the constant minute changes in driving conditions
based  on  information  input  from  the  sensors  and
drives  the  actuator.  ECM  is  composed  of  32-bit
microprocessor and Random Access Memory (RAM),
Read  Only  Memory  (ROM)  and  Input  /Output

interface. ECM uses flash-memory ROM that allows
re-writing  of  data  so  that  change  and  correction  of
control  data  is  possible  using  special  tools.  It  also
uses Electrically Erasable Programmable Read Only
Memory  (EEPROM)  so  that  studied  compensation
data  is  not  deleted  even  if  battery  terminals  are
disconnected.
