Body Control Module (BCM)

Body control modules (BCM) depend on highly reliable electronic components to monitor and control a wide variety of car body, security and convenience functions.

A growing number of dedicated BCMs

Due to the increasing complexity, vehicles often have multiple BCMs, each dedicated to a specific sub-system, including: 

  • Lighting control: including incandescent, HID, Xenon, LED lamps and their related diagnostics monitoring (over-load and over-temperature protection, bulb outage detection, etc.); 
  • Motor control drivers for mirrors, wiper, windows, seat position, dome, locks, and climate control; 
  • Security control for immobilizer and NFC keyless entry systems. 

To reduce the weight and size of these systems, relays are increasingly being replaced by integrated power devices with embedded diagnostics.
