Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Image Processing Control Module (IPCM): Notes
There are two Blindspot Monitoring Control Module (BMCM)'s and they are located in the corner of the rear bumper, one on each side.
Each BMCM connector has power, ground, HS CAN comfort bus wires, and two private CAN wires.
The system uses two radar sensors; they are incorporated in each of a BMCM's, that are located at the rear of the vehicle (one module each side) and are connected via a private CAN bus to exchange information.
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 blind spot monitoring modules receive vehicle speed on the HS CAN comfort bus. The system activates at 9 mph (15km/h) and remains active until the speed lowers below 3mph (5km/h).
