ADJUSTMENT
CAUTION:
-
Do not stare at the luminous portion of the laser during adjustment. The intensity of the laser light is low, but it may result in loss
of sight.
-
If the operation is not carried out as specified, there may be a risk of exposure to hazardous radiation.
HINT:
-
After replacing the ECM on vehicles with a dynamic laser cruise control system, it is necessary to initialize the ECM so that the ECM can
recognize the dynamic laser cruise control system See: Cruise Control/Testing and Inspection/Programming and Relearning.
-
After replacing the distance control ECU, it is necessary to initialize the distance control ECU so that the ECU can recognize the
specification of the vehicle See: Cruise Control/Testing and Inspection/Programming and Relearning.
-
There is a limitation on laser beam 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 beam axis after the operation.
1. ADJUST LASER SENSOR
NOTICE:
-
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 it is impossible to secure a distance of approximately 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.
(a) Preparation for adjusting the laser beam axis
(1) Adjust the tires pressure properly See: Maintenance/Wheels and Tires/Testing and Inspection/Component Tests and General Diagnostics.
(2) Luggage in the vehicle, such as in the trunk, should be unloaded.
(3) Clean the light-emitting and light-receiving portions of the laser sensor.
(4) 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.
(b) Reflector (SST) placement
