Laser Sensor: Adjustment

HINT:

• There is a limitation on laser optical axis adjustment.
• Since the laser sensor is installed in the bumper reinforcement, it is important that the laser sensor, bumper reinforcement, and other related parts are installed properly.
• When the sensor is removed from the vehicle for trouble diagnosis or repair, it is necessary to adjust the laser optical axis after the operation.

1. ADJUST LASER SENSOR 
   NOTE:

   • Perform measurement indoors on a level ground and in front of a blank wall. Park the vehicle at least 9 m (29.53 ft) from the wall. When performing adjustment outdoors, make sure that it is not raining or snowing.
   • Check that there are no reflective materials in the surroundings or on the ground.
   • If you can not secure a distance of about 9 m (29.53 ft) in front of the vehicle, be sure to secure at least 7 m (22.97 ft) from the vehicle, and cover the area marked [A] with a black cloth. If not covered with a black cloth, the laser sensor may detect something other than the target and it will fail to adjust properly.
   1. Preparation for adjusting the laser optical axis
      1. Adjust the tire pressure properly (see INSPECTION ).
      2. Luggage in the vehicle, such as in the trunk, should be unloaded.
      3. Clean the light-luminous and light-receiving portions of the laser sensor.

      HINT:

      Prepare a 10 m (32.81 ft) string, a string with a sharp-pointed weight (plumb bob), and a 5 m (16.41 ft) tape measure.
