DTC U1102 Lost Communication with Radar SensorDESCRIPTION
DTC Detection Condition:
The millimeter wave radar sensor and distance control ECU transmit the data for general vehicle control and diagnosis function along the communication line. The distance control ECU determines the curve radius information based on signals from the steering wheel and yaw rate sensor. The distance control ECU transmits the current vehicle speed and curve radius information to the millimeter wave radar sensor.
