BLINDSPOT Monitoring Control Module (BMCM)
There are two Blindspot Monitoring Control Modules (BMCM) and they are located in the corner of the rear bumper, one on each side.
Each BMCM connector has power, ground, High Speed (HS) Controller Area Network (CAN) comfort bus wires, and two private CAN wires.
The system uses two radar sensors; they are incorporated in each of a BMCMs, and are connected via a private Controller Area Network (CAN) bus to exchange information with each other.
Each BMCM carries out an auto-alignment self-check every time when in use. This procedure can take up to an hour in some environments; however the operation of the blindspot monitoring system will continue to operate as normal.
The BMCM receives vehicle speed from the Anti-Lock Braking System (ABS) control module via the HS CAN. The system activates at 15km/h (9 mph) and remains active until the speed lowers below 3 mph (5 km/h).
