FRONT CAMERA SYSTEM(for Mono Camera Type), Diagnostic DTC:C1A11, C1A14

DTC Code DTC Name
C1A11 Front Radar Sensor Incorrect Axial Gap
C1A14 Front Radar Sensor Beam Axis Not Adjusted

DESCRIPTION

The forward recognition camera uses the millimeter wave radar sensor assembly to detect obstacles in front of the vehicle.

When the vehicle is determined to be driving in a straight line or on a gradual curve based on signals from the yaw rate sensor etc., the millimeter wave radar sensor assembly performs self diagnosis to check if the sensor beam axis has deviated from the vehicle movement direction. When the millimeter wave radar sensor assembly beam axis has deviated, the forward recognition camera detects this, and stores DTC C1A11.

After installing a new millimeter wave radar sensor assembly, if sensor beam axis adjustment is not performed, DTC C1A14 is stored.

DTC No. Detection Item DTC Detection Condition Trouble Area
C1A11 Front Radar Sensor Incorrect Axial Gap 2 seconds after the power switch is turned on (IG), misalignment of the millimeter wave radar sensor assembly is detected for approximately 5 seconds. Pre-collision system
C1A14 Front Radar Sensor Beam Axis Not Adjusted 2 seconds after the power switch is turned on (IG), incompletion of the millimeter wave radar sensor beam axis alignment is detected for approximately 5 seconds. Pre-collision system
