Dynamic Laser Cruise Control System
DTC U0122 Lost Communication with Vehicle Dynamics Control ModuleDESCRIPTION
DTC Detecting Condition:
The skid control ECU and hybrid vehicle control ECU transmit the data for vehicle general control and diagnosis function along the communication line.
The dynamic laser cruise control system receives information about the laser radar sensor, steering angle sensor and yaw rate sensor from the skid control ECU. It identifies the vehicle in front and follows it keeping a proper vehicle-to-vehicle distance.
When the skid control ECU receives the steering angle signal from the steering angle and the acceleration/deceleration signal from the yaw rate sensor, it transmits them to the hybrid vehicle control ECU.
HINT: This circuit uses CAN communication. Therefore, if there are any malfunction in the communication circuit, one or more DTCs in the CAN communication system are output.
