DTC C1A10 Front Radar Sensor


DESCRIPTION

The forward recognition camera uses the millimeter wave radar sensor assembly to detect obstacles in front of the vehicle.
When the forward recognition camera receives information that there is a malfunction in the millimeter wave radar sensor assembly, DTC C1A10 is stored.

DTC No.
DTC Detection Condition
Trouble Area

2 seconds after the engine switch is turned on (IG), a signal from the millimeter wave radar sensor assembly indicating that there is an internal malfunction in millimeter wave radar sensor assembly is detected by the forward recognition camera for 5 seconds or more.
  1. Millimeter wave radar sensor assembly
  2. Forward recognition camera

INSPECTION PROCEDURE

NOTICE:
  1. 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.
  2. If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera learning (Click here).
  3. When the millimeter wave radar sensor assembly is replaced with a new one, adjustment of the radar sensor beam axis must be performed (Click here).
  4. First check the CAN communication system by following How to Proceed with Troubleshooting. After checking that there are no malfunctions in the CAN communication system, proceed with troubleshooting (Click here).
