Perform variant coding.

The FCA radar sensor alignment is required when:

The sensor can not recognize a vehicle ahead:

Stop the vehicle horizontally at a flat place.

• Adjustment may not be accurate if the installation surface height and angle of the vehicle and reflector are different. • Perform in an area with minimum clearance of 8m (26.2 ft) front, 4m (13.1 ft) sides, and 1.2m (3.9 ft) above the vehicle. • Remove heavy objects from inside of the vehicle (seating area and trunk). • Ensure that all tires are filled with spec air pressure. • Remove objects (metal plates, resins, etc.) that may cause electric signal interference from the area where sensor alignment is performed. • Be sure that the vehicle is not moved and free from vibration when performing sensor alignment (getting in/out or opening/closing doors). • Check that radiator grill and sensor cover is not dirty. • Check that the wheel alignment is normal. • Do not turn OFF the power when performing sensor alignment. • Power supplied to the radar sensor must be between 9V-16V. • Temperature in the area where sensor alignment is performed must be between -30 - 60°C (-22 - 140 °F).

Mark the center point of emblem (A) and the center point on top of wind glass (B).

Connect the SCC Calibration Laser (SST No. : 09964-C1200) to the tripod (SST No. : 09964-C1300).

By using the SCC Calibration Reflector [SST No. : 09964-C1100] (A), adjust the wire (D) so that the center point of emblem (B) and the center point on the ground (C) are perpendicular to each other.

Install the vertical/horizontal laser [SST No. : 09964-C1200] (A) at over 4.2m (12.5 ft) to the front of the vehicle.

Match the vertical line of laser to (A) and (B) using the vertical/horizontal laser (C) [SST No. : 09964-C1200].

Mark (C) at 1.0 - 3.8 m (3.3 - 12.5 ft) from (A) in front of the vehicle.

Remove the SCC Calibration Laser [SST No. : 09964-C1200] (B) from the tripod [SST No. : 09964-C1300] (A).

Mount the reflector [SST No. : 09964-C1100] (B) onto the tripod [SST No. : 09964-C1300] (A).

Align the vertical weight (B) of the SCC Calibration Reflector [SST No. : 09964-C1100] (A) with the point (C).

Using the bubble level (B) of the tripod [SST No. : 09964-C1300] (A), set the reflector horizontally.

Set the height of the SCC calibration reflector [SST No. : 09964-C1100] (A) to 330 mm (13.0 inch).

Check again the radar sensor and the surface of front bumper for the following items with the eyes.

• Visually check that the reflecting side of the reflector is levelled with the front of the vehicle. • Make sure that there is no debris, or reflecting object on the surface of the radar. • Make sure that there is no debris, or reflecting object on the radiator grill.

Connect the KDS to the DLC of the vehicle and start sensor alignment.

If the engine is running, the vibration may cause inaccurate sensor alignment, so perform sensor alignment in IG ON mode.

After correctly selecting the vehicle model, select "Radar Sensor Alignment" from the auxiliary functions in KDS Menu.

Perform sensor alignment by following the directions shown in the KDS monitor.

In case of sensor alignment failure, check the alignment conditions. Turn the ignition key OFF, then reperform the sensor alignment procedure.

Check the bumper appearance and accident history (visual appearance of the vehicle, maintenance and bumper replacement history).

→ If the vehicle has been crashed, FCA mounting part is highly likely to be twisted.

Check whether the radar sensor cover of the bumper is dirty.

→ If the cover is dirty, FCA is highly likely to be released by the foreign substance during operation.

After starting engine, check FCA warning message on the cluster and DTC code. (Refer to DTC guide.)

After starting engine, stop for more than 5 seconds.

→ If system initialization (yaw rate sensor offset compensation) is not completed, FCA will not operate.
