EMCM (Energy Management Control Module)
EMCM is an ECU which controls the stop/start system and alternator regeneration. EMCM judges vehicle condition based on signals from each sensor and information from each ECU via CAN communication and controls the stop/start system and alternator regeneration in cooperation with ECM.
EMCM is connected to the CAN communication circuit and receives signals directly from each ECU. EMCM transmits signals via ECM to each ECU.
