Code U1193 Dodge Description

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 Controller Area Network (CAN) bussed message to the corresponding door module for a LED blind spot warning light request. The Diagnostic Trouble Code (DTC) sets when the Right Blind Spot Sensor (RBSS) does not receive messages from the Left Blind Spot Sensor (LBSS).
