LKA/LDA SYSTEM(for Mono Camera Type), Diagnostic DTC:U0235

DTC Code DTC Name
U0235 Lost Communication with Cruise Control Front Distance Range Sensor

DESCRIPTION

The forward recognition camera communicates with the driving support ECU assembly and millimeter wave radar sensor assembly via CAN communication. If there is a communication error with the millimeter wave radar sensor assembly, the forward recognition camera stores DTC U0235.

DTC No. Detection Item DTC Detection Condition Trouble Area
U0235 Lost Communication with Cruise Control Front Distance Range Sensor 2 seconds after the power switch is turned on (IG), a communication error between the millimeter wave radar sensor assembly and the forward recognition camera is detected for approximately 5 seconds.

  • CAN communication system

  • Millimeter wave radar sensor assembly

  • Forward recognition camera

CAUTION / NOTICE / HINT

Note


  • When replacing the millimeter wave radar sensor assembly, always replace it with a new one. If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in the millimeter wave radar sensor assembly will not match the information from the vehicle. As a result, a DTC may be stored.

  • When the millimeter wave radar sensor assembly is replaced with a new one, adjustment of the radar sensor beam axis must be performed.

  • When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.

  • If the forward recognition camera has been replaced with a new one, be sure to perform Forward Recognition Camera Learning.

PROCEDURE


  1. CHECK FOR DTCs (PRE-COLLISION SYSTEM and FRONT CAMERA SYSTEM)


    1. Check for DTCs.

      Tech Tips

      The malfunction area can be determined by the combination of DTCs output at the same time.
