Dynamic Radar Cruise Control System
DTC P1615 Communication Error from Distance Control ECU to ECMDTC U1101 Lost Communication with Distance Control ECU
DESCRIPTION
DTC Detection Condition:
The distance control ECU receives information about the area in front of the vehicle from the millimeter wave radar sensor and then sends a brake control demand signal (deceleration demand) and diagnosis signals, such as millimeter wave radar sensor grime signals or millimeter wave radar sensor malfunction signals, to the ECM.
HINT: This circuit uses CAN communication. Therefore, if there are any malfunctions in the communication circuit, one or more DTCs in the CAN communication system are output.
