Lost Communication With Passenger Side Blind Spot Sensor - Missing Message

Cause of DTC

The Blind Spot Monitor (BSM) system used in this vehicle has two control modules. One control module is dedicated to each side of the vehicle. The blind spot modules are each integral to the blind spot sensor for the same side of the vehicle. If the sensor detects a vehicle in the blind spot path, the module will send a CAN bussed message to the corresponding door module for a LED blind spot warning light request.
