CRUISE CONTROL LANE TRACING ASSIST SYSTEM PROBLEM SYMPTOMS TABLE

NOTICE:

When replacing the forward recognition camera, 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 and a DTC may be stored.

When the forward recognition camera is replaced or removed/installed, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history (RoB) for each system.

HINT:: Perform forward recognition camera optical axis alignment with either "One time recognition" or "Sequential recognition". Refer to the following for clearing the vehicle control history.; One time recognition: Click hereEngine / Hybrid System>CRUISE CONTROL>FRONT CAMERA>TARGET ADJUSTMENT(ONE TIME RECOGNITION)202409,999999,_51,_083055,_0401005,RM100000002NTD0,; Sequential recognition: Click hereEngine / Hybrid System>CRUISE CONTROL>FRONT CAMERA>TARGET ADJUSTMENT(SEQUENTIAL RECOGNITION)202409,999999,_51,_083055,_0401005,RM100000002NTD3,; Driving Adjustment: Click hereEngine / Hybrid System>CRUISE CONTROL>FRONT CAMERA>DRIVING ADJUSTMENT202409,999999,_51,_083055,_0401005,RM100000002NTD4,

When the forward recognition camera is replaced, update the ECU security key.

When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in the combination meter assembly will not match the information from the vehicle, and may cause a DTC to be output.

When the combination meter assembly is replaced, update the ECU security key.

HINT:: ·

If no problem symptoms are found when a DTC is output in the DTC check on the lane tracing assist system, check each symptom by checking the suspected areas in the order they are listed.

·

Before performing failure diagnosis according to the following inspection points, check the forward recognition camera system power source circuit fuses and relays.
