ADVANCED DRIVER ASSISTANCE SYSTEM LANE TRACING ASSIST SYSTEM U023587 Lost Communication with Cruise Control Front Distance Range Sensor Single Sensor or Center Missing Message
DESCRIPTION
The forward recognition camera communicates with the millimeter wave radar sensor assembly via CAN communication. If a communication malfunction between the forward recognition camera and millimeter wave radar sensor assembly is detected, DTC U023587 is stored.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | DTC Output from | Priority |
