CRUISE CONTROL  LANE TRACING ASSIST SYSTEM  U023587  Lost Communication with Cruise Control Front Distance Range Sensor Single Sensor or Center Missing Message  

The forward recognition camera is connected to the millimeter wave radar sensor assembly via the CAN communication line. When the signal from the millimeter wave radar sensor assembly is interrupted, the forward recognition camera outputs U023587.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
U023587	Lost Communication with Cruise Control Front Distance Range Sensor Single Sensor or Center Missing Message	After 3 seconds or more have elapsed since turning the lane tracing assist system on and the ignition switch to ON, a communication data malfunction continuously occurs between the forward recognition camera and millimeter wave radar sensor assembly for approximately 5 seconds or more	Pre-collision system

HINT:

If the DTCs are output simultaneously, the inspection area can be narrowed down.
