On-Vehicle Inspection [10/2023 - ]: Procedure

Refer to PROCEDURE - Step 2

HINT: 

The front side radar sensor installation condition inspection is performed to confirm whether the sensor is perpendicular to the floor surface (+/- 2.2°) by using a digital angle gauge, and that the sensor is 26 to 34° from the line parallel to the vehicle center line.

1. Horizontal mounting angle check
   1. Hang a weight with a pointed tip from the center of the rear emblem, and mark the rear center point of the vehicle (point A) on the ground.

      *a	String	*b	Weight
      *c	Center point	*d	Bilateral Symmetry

      HINT: 

      Lightly flick the string with your fingers several times to confirm that the string is aligned with mark A.

   2. Hang a weight with a pointed tip from the center of the radiator grille (or front panel) emblem, and mark the front center point of the vehicle (point B) on the ground.

      *c	Center point	*d	Bilateral Symmetry

      HINT: 

      Lightly flick the string with your fingers several times to confirm that the string is aligned with mark B.

   3. Draw a vehicle center line so that it passes through mark A and B (front and rear center points).

   4. Remove the front bumper assembly.

      Refer to REMOVAL [10/2023 - ]

   5. Attach double-sided tape to the digital angle gauge attachment A as shown in the illustration.

      *a	SST (Digital Angle Gauge Attachment A)
      	Double-sided Tape

      HINT: 

      • Make sure to use double-sided tape with the same thickness for both the left and right sides.
      • If the thickness of the double-sided tape is different for the left and right sides, an accurate measurement cannot be performed.
   6. Remove the release paper from the double-sided tape, and attach the digital angle gauge attachment A to the front side radar sensor.

   7. Mark points C and D on the ground by hanging a pointed weight from two points at the side part of the convex surface of the radome, as shown in the illustration.

      Standard

      Location	Measurement
      a	55 mm (2.17 in.)

      HINT: 

      Make sure the string hangs straight down so that it does not contact parts of the vehicle.

   8. Check that the following dimensions are obtained based on point C and point D.

      *A	Vehicle Front (LH)
      *a	Vehicle Front
      *b	Vehicle Rear
      *c	Vehicle Center Line
      *d	Line Parallel to Vehicle Center Line
      *e	Line Perpendicular to Vehicle Center Line

      Standard

      Location	Measurement
      y	24 to 31 mm (0.94 to 1.22 in.)

      HINT: 

      If the results are not as specified, it is possible that the front side radar sensor installation area (frame, head light assembly) is deformed, so make corrections as necessary.

2. Vertical mounting angle check
   1. Place the digital angle gauge on a level (gradient within 1%) and perform zero-point adjustment as shown in the illustration.

      *a	(+)	*b	(-)
      *c	When Storing Zero Point	*d	After Storing Zero Point, Indicates 90° When Fully Horizontal

   2. Set the digital angle gauge to the outward facing surface of the front side radar sensor as shown in the illustration, and check that the perpendicular angle of the front side radar sensor is within the permissible range.

      *1	Front Side Radar Sensor
      *a	Digital Angle Gauge
      *b	Outward Facing Surface

      NOTE:

      The sensor angle is the measured sensor angle subtracted from 90°.

      *a	(+)
      *b	(-)
      *c	Horizontal Line
      *d	Digital Angle Gauge
      *e	Outward Facing Surface

      HINT: 

      • The digital angle gauge should indicate 90° when turned on its side.
      • The outward facing surface (installation angle) is positive (+) when it faces higher than horizontal.

      Standard

      Item	Allowable Range
      Front Side Radar Sensor (for LH Side)	-2.2 to +2.2°
      Front Side Radar Sensor (for RH Side)	-2.2 to +2.2°

3. Install the front bumper assembly.
