It replaces separate components such as the central locking module, the timer relay and the fuse box in the passenger compartment. It consists of a power distribution section (including fuses and relays) and an electronic control module, which controls the operation of most of the vehicle's electronic systems. New vehicles are supplied with different versions of the BCM (depending on the equipment specification of the vehicle). When installing a replacement BCM it needs to be configured for the specific vehicle. The following functions are controlled or executed by the BCM if the battery voltage is between 9 and 16 V. ‡ Battery saving function ‡ Current distribution ‡ Exterior lighting ‡ Interior lighting ‡ Wiper system ‡ Washer fluid level indicator ‡ Window heating (heated windshield, heated rear window, heated exterior mirrors) ‡ Speed control system (reads the speed control switches and transmits signals on the CAN bus) ‡ Locking / Unlocking ‡ Anti-theft ‡ Air conditioning controls (partial) ‡ Handbrake (it monitors the switch and transmits the signal on the CAN bus) ‡ Monitoring of the brake fluid level. ‡ Electric fuel pump (mechanical fuel pump on diesel engines is not BCM controlled) ‡ Fuel level indicator ‡ Battery charging (smart charge, partially) ‡ Electric booster heater ‡ Brake pedal position (BPP) switch. ‡ Communications via the high speed CAN bus (HS-CAN) and mid-speed CAN bus (MS-CAN) ‡ Main module in the LIN bus system ‡ PATS (interface for transceiver) ‡ BTSI (brake transmission shift interlock) ‡ Central module configuration ‡ Power management (vehicle mode) The BCM can be diagnosed via the diagnostic tool. Furthermore, an integrated service mode enables testing of the input and output signals without the need for further tools. Emergency function The BCM is equipped with restricted emergency running functions on all vehicles. A monitoring function within the BCM is sent a control signal at regular intervals by the
