DESCRIPTION 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. If the millimeter wave radar sensor assembly beam axis has deviated, the millimeter wave radar sensor assembly detects this and stores DTC C1A11.
CAUTION / NOTICE / HINT NOTICE:
PROCEDURE
(a) Check the operating conditions of the vehicle. HINT: DTC C1A11 may be stored if the millimeter wave radar sensor assembly beam axis is temporarily misaligned due to the vehicle being overloaded.
(a) Check the wheel alignment (toe). Click here HINT: DTC C1A11 may be stored if the millimeter wave radar sensor assembly beam axis is misaligned due to incorrect wheel alignment (toe).
(a) Adjust the alignment (toe) of the wheels. Click here
(a) Perform millimeter wave radar sensor assembly adjustment. Click here
(a) Clear the DTCs. Click here (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. Click here
(a) Check that the bracket of the millimeter wave radar sensor assembly is not deformed. HINT: If the bracket is deformed, replace the millimeter wave radar sensor assembly. OK: The bracket is not deformed.
(a) Replace the millimeter wave radar sensor assembly. Click here (b) Adjust the millimeter wave radar sensor assembly. Click here
(a) Clear the DTCs. Click here
(a) Return the vehicle to normal. (b) Perform millimeter wave radar sensor assembly adjustment. Click here
(a) Clear the DTCs. Click here (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. Click here
