If a level surface is not available, this tech tip should be used in conjunction with the repair manual to set the angle of the front millimeter wave radar sensor and reflector height before performing beam axis adjustment. RECOMMENDATIONS PREPARE VEHICLE FOR CALIBRATION REFER TO THE APPLICABLE VEHICLE’S REPAIR MANUAL FOR CALIBRATION PREPARATION Expires on Ver. 3.0 08/27/2019 L 03/26/2021 © 2019, Lexus, a Division of Toyota Motor Sales, USA Page 1 of 5 Tech Tip L-TT-0284-20 March 26, 2020 Subject Market Millimeter Wave Radar Sensor Floor Slope Compensation USA Applicability Lexus Models with Manually Adjusted Front Millimeter Wave Radar Sensor RECOMMENDATIONS DETERMINE FLOOR SLOPE AND SET VERTICAL ANGLE OF MILLIMETER WAVE RADAR SENSOR FLOOR SLOPE AND VERTICAL ANGLE CALIBRATION VIDEO 1. INSTALL THE LASER LEVEL ONTO THE TRIPOD A. Install the tripod head attachment onto the base of the laser level. B. Engage the tripod head attachment onto the tripod and lock it in position. SST: 01816-00103 (Laser Level) DEMO VIDEO 01816-00104 (Tri-pod) 2. MEASURE THE FLOOR SLOPE ON BOTH SIDES OF VEHICLE A. Place the tripod and laser approximately 6 ft. away from the side of the vehicle. B. Level the tripod base and head using the built-in bubble levels. C. Turn on the laser and ensure that the laser switch is placed in the UNLOCKED position, so it can automatically level. D. Measure the distance from the floor to the laser line at the vertical center of the front wheel and record the value. NOTE: Measure using either inches or millimeters. E. Measure the distance from the floor to the laser line at the vertical center of the rear wheel and record the value. F. Repeat steps A-E for the opposite side.

CALCULATE VERTICAL ANGLE FOR MILLIMETER WAVE RADAR SENSOR A. Open the slope calculator link, select the appropriate vehicle from the dropdown, and enter the measured values at each wheel in the correct locations. NOTE: Ensure the correct measurement value (inches or mm) is selected prior to calculating. B. Press the finalize button and then press calculate. C. The sheet will calculate the required vertical angle and reflector height adjustment based on the floor slope. Record these readings. SLOPE CALCULATOR LINK 4. SET VERTICAL ANGLE OF MILLIMETER WAVE RADAR SENSOR A. Clean the top of the radar sensor surface and SST "Attachment A” mounting surfaces of any dust and debris. B. Place “Attachment A” (short or long depending on available clearance) on top of the radar sensor calibration surface as shown. C. Place the digital angle gauge on “Attachment A” with the screen facing the passenger side of the vehicle and retrieve sensor angle. NOTE: Once the digital angle gauge has been powered on, the unit must be set to “Absolute Mode”, ABS will be displayed in the upper right corner of the display.

Adjust the radar vertical angle to the value calculated on the slope calculation sheet. SET TARGET PLACEMENT AND PERFORM SENSOR CALIBRATION 1. LOCATE AND MARK THE CENTER LINE OF THE VEHICLE PER THE APPLICABLE VEHICLE’S REPAIR MANUAL 2. LOCATE THE REFLECTOR SST CALIBRATION POSITION PER THE APPLICABLE VEHICLE’S REPAIR MANUAL 3. SET REFLECTOR HEIGHT REFLECTOR HEIGHT ADJUSTMENT PROCEDURE VIDEO A. Place the tripod and laser level in front of the vehicle. B. Level the tripod base and head using the built-in bubble levels. C. Turn on the laser level to the UNLOCKED position with both the vertical and horizontal laser lines being projected. D. Adjust the height of the tripod head and laser until the laser line crosses the center of the front emblem as shown. E. Turn the self-leveling laser 180 degrees and toward the reflector stand.
