CRUISE CONTROL  FRONT CAMERA SYSTEM  C1AAE00  Front Recognition Camera Heater Malfunction  


DESCRIPTION

The forward recognition camera controls the flow of current to the forward recognition with heater hood sub-assembly.

If the forward recognition camera detects a malfunction in the forward recognition with heater hood sub-assembly circuit, it will store this DTC.

DTC No. Detection Item DTC Detection Condition Trouble Area

CAUTION / NOTICE / HINT

NOTICE:
·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

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 adjustment.

HINT:

Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition.

One Time Recognition: Click hereEngine / Hybrid System>CRUISE CONTROL>FRONT CAMERA>ADJUSTMENT (ONE TIME RECOGNITION)

Sequential Recognition: Click hereEngine / Hybrid System>CRUISE CONTROL>FRONT CAMERA>ADJUSTMENT (SEQUENTIAL RECOGNITION)




PROCEDURE

1.CHECK FOR DTCs
a.

Clear the DTCs.

b.

Make sure that the DTC detection conditions are met.

HINT:

If the detection conditions are not met, the system cannot detect the malfunction.



c.

Check for DTCs.
