EMCM (Energy Management Control Module)
WARNING: This page is about a different car, the 2018 Infiniti Q60. However, it is still accessible from the selected car via links, so may be relevant.
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.
