DTC U0235: Lost Communication with Cruise Control Front Distance Range Sensor; DTC U1002: Lost Communication with Gateway Module; DTC U1104: Lost Communication with Driving Support ECU [08/2015 - ]: Description
The driving support ECU assembly sends vehicle speed and vehicle condition information to the millimeter wave radar sensor assembly. The millimeter wave radar sensor assembly then sends information on the presence, distance, and relative speed of objects ahead to the driving support ECU assembly. The driving support ECU assembly sends this information to the ECM and performs pre-collision system operation.
