Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2.
Remove the front bumper.
(Refer to Body - "Front Bumper")
3.
Disconnect the smart cruise control unit connector (A).
4.
Loosen the nuts (A) and bolt (B), and then remove the smart cruise control unit assembly (C) from the vehicle.
Installation
1.
Install in the reverse order of removal.
Ensure that the side surface of the smart cruise control
(SCC) unit is perpendicular to the level ground using the SST
0K964-3T000 (A).
Smart cruise control unit installation bolt/nut:
7.8 ~ 11.8 N.m (0.8 ~ 1.2 kgf.m, 5.8 ~ 8.7 lb-ft)
2.
Perform the smart cruise control radar sensor alignment procedure.
(Refer to "Smart Cruise Control Sensor Alignment")
3.
Install the front bumper.
(Refer to Body - "Front Bumper")
Smart Cruise Control (SCC) Radar Sensor Alignment
Smart Cruise Control (SCC) unit detects a forward vehicle and
then recognizes the distance to the forward vehicle and the relative
speed using the built-in radar sensor. In order for the radar sensor to
operate correctly, it must be properly aligned parallel to the driving
direction of the vehicle. So, the radar sensor alignment procedure must
be carried out after the sensor is reinstalled or replaced with new one.
If not performing the sensor alignment in the conditions mentioned
above, the smart cruise control system may not operate correctly.
The SCC radar sensor alignment is required when:
•
The SCC unit is reinstalled or replaced with a new one.
•
The radar sensor or the surrounding parts are impacted by a collision.
•
The sensor does not recognize a forward vehicle.
•
The Steering Angle Sensor (SAS) is replaced or adjusted.
Preparation before the SCC radar sensor alignment:
•
Put the vehicle on the level ground.
•
Take out heavy luggage from the vehicles’ seats or trunk.
•
Set all tires according to the specified pressure.
•
Check wheel alignment.
•
Check that the front surface of the SCC unit is clean.
Radar sensor should be aligned in both vertical and lateral
direction. Vertical alignment can performed by using the SST
(0K964-3T000) and lateral alignment can be performed automatically by
driving on a road.
1.
Park the vehicle on a level ground.
2.
Remove the front bumper.
(Refer to Body - "Front Bumper")
3.
Check the vertical alignment of the radar sensor using the SST 0K964-3T000 (A).
If the vertical alignment is out of the the tolerance, turn
the adjustment screw (B) until the alignment is within the tolerance.
Tolerance: ±1.25⁰ or less
4.
Install the front bumper.
(Refer to Body - "Front Bumper")
5.
To perform the lateral alignment, connect the GDS with the engine started and select the “SCC Alignment (Calibration) “.
Be sure to erase DTC before performing the lateral alignment.
6.
Press “OK” to start sensor alignment.
7.
Follow the Driving Mode procedure described in the GDS.
The lateral alignment takes about 5 to 15 minutes generally
but it can be shorten or extended depending on the road condition or
driving condition.
•
Road or driving conditions for shortening the alignment :
–
Driving at more than 65 km/h (40.4 mph)
–
Driving on a road without curve and slope
–
Driving on a thick and wide paved road
–
Driving on a road where there are repetitive and fixed targets (metal materials such as street lights or guard rails)
–
Driving on a dry road without rain or snow
•
Road or driving conditions that can interrupt the alignment process
–
Driving a road with the sharp curve where the radius is within 100m (328.0ft)
–
Driving at a lower speed than suggested above or during a stop due to a red light
–
Driving in a tunnel or under an overpass
–
Turning the steering wheel excessively to the left or right or changing the lane suddenly
Be sure to follow the below safety guidelines while driving the vehicle for the lateral alignment :
•
Observe a regulation speed
•
Do not drive too fast for shortening the sensor alignment. Drive safely considering the road condition and traffic situation.
•
Do not stare the GDS screen or operate the GDS while driving. Only while stopping, the GDS should be operated.
If the lateral alignment is not completed successfully, check
the alignment using the GDS. If the value is out of ±3⁰, check that
the back beam or bracket where the SCC unit is mounted are in a good
condition and then if there is no problems, replace the SCC unit with
new one. After replacing the SCC unit, repeat the alignment procedure
described above.
1. Pull the release lever to unlatch
the hood. The hood should pop
open slightly.
Only open the hood with the vehicle
on a flat surface, engine is
turned off, shift lever placed in P
(Park) position and setting the
parking brake.
2. Go to the front of the vehicle, raise
the hood ...
Removal
•
Take care not to scratch the crash pad and related parts.
1.
Disconnect the negative (-) battery terminal.
2.
Remove the AVN monitor.
(Refer to "AVN System" - "AVN Head Unit")
3.
Remove the TMU unit (A) after loosening the mounting ...
