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.
