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.
