PRE-COLLISION SYSTEM, Diagnostic DTC:C1AA0, C1AA8, C1AA9, C1AAE

DTC Code DTC Name
C1AA0 Front Camera Module Circuit
C1AA8 Front Camera Module Incorrect Axial Gap
C1AA9 Front Camera Module Beam Axis Not Adjusted
C1AAE Heater Circuit

DESCRIPTION

The millimeter wave radar sensor assembly receives information about the area in front of the vehicle from the forward recognition camera.

If the millimeter wave radar sensor assembly detects a malfunction in the forward recognition camera, it will store DTC C1AA0.

If the millimeter wave radar sensor assembly detects that the beam axis of the forward recognition camera is misaligned, it will store DTC C1AA8.

If forward recognition camera adjustment has not been performed or did not complete normally after the forward recognition camera was replaced with a new one, DTC C1AA9 will be stored.

If the forward recognition camera detects a malfunction in the camera heater (forward recognition hood) circuit, it will output a malfunction signal to the millimeter wave radar sensor assembly via CAN communication and DTC C1AAE will be stored.

DTC No. Detection Item DTC Detection Condition Trouble Area
C1AA0 Front Camera Module Circuit While the engine switch is on (IG), the forward recognition camera detects an internal malfunction for approximately 1 second or more. Forward recognition camera system
C1AA8 Front Camera Module Incorrect Axial Gap While the engine switch is on (IG), the millimeter wave radar sensor assembly continuously receives a signal indicating that the beam axis of the forward recognition camera is misaligned for 1 second or more. Forward recognition camera system
C1AA9 Front Camera Module Beam Axis Not Adjusted While the engine switch is on (IG), the millimeter wave radar sensor assembly detects that forward recognition camera adjustment has not been completed for 1 second or more. Forward recognition camera system
C1AAE Heater Circuit When the engine switch is on (IG), the millimeter wave radar sensor assembly receives a camera heater (forward recognition hood) circuit malfunction signal from the forward recognition camera continuously for 5 seconds or more. Forward recognition camera system
