DTC U1104: Lost Communication with Driving Support ECU [10/2015 - ]: Description
The driving support ECU assembly is connected to the millimeter wave radar sensor assembly, forward recognition camera and brake actuator assembly (skid control ECU) via CAN communication. If communication with the millimeter wave radar sensor assembly, forward recognition camera or brake actuator assembly (skid control ECU) stops, the driving support ECU assembly stores DTC U1104.
