General Description

RAM is a component of BCM that consists of DDM, ADM, IPM, FAM, IMS and cluster module. Each part of BCM is connected to one another through CAN communication line for efficient communication. Those modules control front/rear, driver/passenger seat, cluster with electrical signal and they share information with other modules. RAM (Rear Area Module) set up at rear-left of passenger room controls various rear lamps (tail lamp, rear turn signal lamp, backup lamp, stop lamp, cabin lamp), window (sliding door power window, quarter glass, rear defogger), rear wiper and oil cap door. the power of stop lamp is supplied from the power line through FAM->stop lamp->RAM->lamp in sequence. Controlling stop lamp is performed at FAM and RAM. FAM transfers power from "HOT AT ALL TIMES power circuit" to stop lamp switch and via RAM, this power is supplied to stop lamp. Furthermore, RAM senses stop lamp circuit error as well.
