The Body Control Module (BCM) receives inputs from various switches and sensors and sends commands, some in the form of multiplex voltage signals, to corresponding components to operate them. Some circuits are controlled by the BCM in conjunction with the IPDM or the Powertrain Control Module (PCM). The circuits under BCM control include the combination switch system, signal buffer system, power consumption control system, auto light system, turn signal and hazard warning light system, headlight system, fog light system, daytime running lights system, interior illumination system, interior illumination battery saver system, step light system, windshield wiper/washer system, rear window wiper/washer system, warning chime system, power door lock system, power window system, Nissan anti-theft system (NATS), vehicle security system, rear window defogger system, remote keyless entry system, intelligent key system, retained accessory power (RAP) system, and tire pressure monitoring system. The BCM is located under the driver's side of the instrument panel, to the right of the steering column. Removal and installation of the BCM is not covered due to the requirement of special equipment for diagnosis and the systems it controls. Additionally, if the BCM requires replacement, it must be programmed with the same special equipment before it will function, necessitating that diagnosis and replacement be performed at a dealer service department or other qualified repair shop equipped with the necessary tools.
