FCA ON/OFF is set in the USM (User Settings Mode) menu and is ON by default.
While IGN is on, the setting remains on; however, the driver setting is not changed the next time IGN is turned on again.
When VDC is off, FCA is also off.
Vehicle Inspection Procedure for Forward Collision-Avoidance Assist Malfunction
Check the bumper for signs of collision damage (visually inspect the vehicle and check the bumper replacement history). → If the vehicle has been in a collision, there is a high possibility that the FCA radar is out of its default original position.
Check the radar sensor cover on the bumper for contamination. → If contaminated, there is a high possibility that the FCA system will be disabled during operation due to foreign substances.
After starting the engine, check the FCA warning lamp and DTCs. (Refer to the Diagnostic Trouble Code Troubleshooting Manual.)
Removal
Be careful not to damage parts located under the vehicle (floor under cover, fuel filter, fuel tank, and canister) when lifting the vehicle with a lift. (Refer to General Information - Jack Lifting Points and Support Points)
[FCA Radar]
Turn the ignition switch OFF and disconnect the negative (-) battery cable.
Remove the front bumper cover. (Refer to Body - "Front Bumper Assembly")
Disconnect the FCA sensor connector (A).
Remove the FCA radar (B) after loosening the FCA radar mounting nuts.
Tightening torque: 3.9 ~ 4.3 N·m
Turn the ignition switch OFF and disconnect the negative (-) battery cable.
Remove the Lane Keeping Assist (LKA) unit. (Refer to Body Electrical System - "Lane Keeping Assist (LKA) Unit")
Unlike SCC with S&G, FCA must operate with the vehicle stationary, so the system uses the Fusion Target system, which combines the radar and the camera.
Installation
[FCA Radar]
Park the vehicle on a level surface.
Remove any heavy luggage from the seats or cargo area.
Inflate all tires to the specified pressure.
Check the wheel alignment.
Make sure the front surface of the front radar is clean.
Check the last 2 digits of the Lot No. There is no (A) on the label at the rear before installing the front radar.
Lot No. (A) value – vertical deviation angle of the inner side of the front radar.
Install the front radar (B) by tightening the nuts.
Tightening torque: 3.9 ~ 4.3 N·m
Connect the front radar connector (A).
If the front radar has been replaced with a new one, perform the variant coding procedure using GDS.
Check and adjust the front radar alignment angle.
Perform the "Front Radar Installation Angle Inspection/Adjustment" using GDS.
Enter the 2-digit value in the code input field, then click "OK".
Check the vertical angle compensating for error using KDS.
The result is the final vertical target angle, which is the compensated internal error. The vertical installation angle criteria is -1°.
Check the front radar vertical angle using a vertical protractor (inclinometer).
Be sure to perform zero setting before using the vertical protractor (perform this procedure periodically).
Note the +/- marks indicated on the vertical protractor.
Adjust the "target vertical angle" by turning the front radar adjusting screw.
Clockwise rotation: adjusts the angle (+)
Counterclockwise rotation: adjusts the angle (-)
There is a risk of deforming the bracket if the adjusting screw is turned with excessive force.
After adjustment, be sure to recheck with the vertical protractor that the vertical angle is correct.

Adjustment
FCA Radar Installation Angle Inspection/Adjustment
Overview
The front radar detects the target object ahead and recognizes the distance to it, the relative speed, etc. For these reasons, the installation direction must be collinear with the vehicle. Therefore, the installation angle inspection and adjustment must be performed when the FCA radar is removed and reinstalled due to an accident, or when a new front radar is installed. The accuracy of the front radar cannot be guaranteed if inspection and adjustment have not been performed in the above situations. The front radar inspection/adjustment must be performed in either the stopped mode (C1) or the driving mode (C2) using GDS. Perform the adjustment procedure with the exclusive adjustment reflector (SST) for the stopped mode (C1).
After stop-mode operation, accuracy will improve if the vehicle has been driven for more than 10 minutes. (Drive on a straight road with metal reflectors.)
Perform adjustment while driving on an actual road (drive on a road with many metal fixed reflectors, such as guardrails) for driving mode. (C2)
Cases in which front radar alignment angle check/adjustment is required.
Front radar has been replaced.
Front radar has been removed and reinstalled.
Line up failed DTC has occurred.
Front radar detection and recognition function malfunction
Fails to detect a preceding vehicle during operation.
Frequently detects lane error.
Frequently detects an error even when no object is ahead.
How to Inspect/Adjust the Front Radar Installation Angle - Stopped Mode
Preparation before front radar alignment:
Park the vehicle on a level surface.
Remove any heavy luggage from the seats or cargo area.
Inflate all tires to the specified pressure.
Check the wheel alignment.
Make sure the front surface of the front radar is clean.
Perform in an area with a minimum clearance of 8 m (26.2 ft) in front, 4 m (13.1 ft) to the sides, and 2 m (6.6 ft) above the vehicle.
Install the reflector exactly 2.5 m (8.2 ft) from the front of the radar.
The reflector must be installed at the same position (height and angle) as the front radar center. (If the height and angle are different, adjustment cannot be performed correctly.)
Remove objects (metal plates, resin, etc.) that may cause signal interference from the area where front radar alignment is performed.
Be sure to use the special reflector (0K964-J5100).
Make sure the vehicle does not move or vibrate when performing front radar alignment (getting in/out or opening/closing doors).
IG must be ON when performing front radar alignment (engine stopped condition).
Park the vehicle horizontally on level ground.
Mark the center point of the emblem (A).
Mark the center point (B) after measuring the distance on the windshield.
Install the laser (09964-C1200) on the tripod (09964-C1300).
Place the laser (09964-C1200) 2.5 m (8.2 ft) from the front of the vehicle.
Align the vertical laser line with (A) and (B) using the laser (09964-C1200).
Mark (C) 2.5 m (8.2 ft) from (A) in front of the vehicle.
Mark (D) the point located 7 mm (0.276 in.) from (C) directly in the vertical direction.
Remove the laser (09964-C1200) from the tripod (09964-C1300).
Install the reflector (09964-C1100) on the tripod (09964-C1300).
Install the reflector adapter (0K964-J5100) on the reflector (09964-C1100).
Set the reflector to a horizontal position using the leveler (A) built into the tripod (09964-C1300).
Align the vertical weight (A) of the reflector (0K964-J5100) with point (D).
Set the height of the reflector adapter (0K964-J5100) to 401 mm (15.78 in.).
Remove the vertical weight from the reflector (0K964-J5100).
This may be performed for adjustment if the vertical weight is still remaining.
Visually check the front radar and the front bumper surface again for any objects.
Make sure there is no debris or reflective objects on the radar surface.
Make sure there is no debris or reflective objects on the radiator grille.
Select C1 (stop mode) to check and adjust the front radar alignment angle, following the procedure on the GDS screen.
If the front radar inspection/adjustment fails, check the inspection/adjustment conditions.
