COMPONENT PARTS

ECM






- ECM (Engine Control Module) controls the engine.
- The ECM consists of a microcomputer and connectors for transmitting/receiving signals and for supplying power. Furthermore, the
ECM is equipped with an injector driver unit and actuates the fuel injector at a high voltage (approximately 70 V at the maximum).
- ECM is equipped with ECM temperature sensors. If ECM is overheated, ECM controls output torque to prevent damage to itself.
- Battery voltage is supplied to the ECM even when the ignition switch is turned OFF for the ECM memory function of the DTC
memory, the air-fuel ratio feedback compensation value memory, the idle air volume learning value memory, etc.
