Body Control Module parts and their functions

5 top-level parts · 163 parts in total · full bill of materials below

#	Part	Qty	What it does
1	Bare PCB	1×	Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
2	Microcontroller	2×	Single-chip microcontroller combining a processor core, flash memory, RAM, and peripherals such as timers, ADCs, and serial ports to run the device's control firmware.
3	CAN Transceiver	2×	Interface chip that converts a controller's logic signals to the differential CAN bus levels and back, letting control units talk to each other.
4	Relay	8×	Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
5	SMD Passive (R/C/L)	150×	Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
