Toyota Sienna Service Manual: 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 operation is not carried out as specified, there may
be a risk that you are exposed 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.
- 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.
- 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, etc. 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 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.
- Preparation for adjusting the laser beam axis
- Adjust the tires pressure properly.
- Luggage in the vehicle such as in the trunk
should be unloaded.
- Clean the light-luminous and light-receiving
portions of the laser sensor.
- Prepare a 10 m (32.81 ft) string, a string with a
sharp-pointed weight, and a 5 m (16.41 ft) tape
measure.
- Reflector (SST) placement
- Measure the height to the center of the laser
luminous portion.
- Adjust the center height of the reflector 48 mm
(1.89 in.) higher than the center of the luminous
portion.
SST 09870-60000 (09870-60010, 09870-
60020)
NOTICE:
Adjust it as precise as possible.
- From the center (center of the emblem) of the
front and rear bumpers, hang down the sharppointed
weight and mark the center points
(both front and rear) of the vehicle on the
ground.
- Fix one end of the string to the rear center mark
and move the other end to the right and left at a
point 5 m (16.41 ft) from the front of the vehicle.
Make a 5 m (16.41 ft) mark when the string and
the front vehicle center mark intersect.
- From the 5 m (16.41 ft) marked position,
measure 569 mm (22.4 in.) to the right and
place the reflector there.
NOTICE:
Perform it as precise as possible.
- Adjust the laser beam axis (procedure [B])
- Turn the ignition switch to ON.
- Push the cruise control main switch button on.
- Connect the intelligent tester to the DLC3, and
turn the power ON.
- Operate by following the screen menu and
select "BEAM AXIS ADJUST" of the Laser
Cruise Control, then press "ENTER".
HINT:
- Pressing "ENTER" will make the ECM
transfer to BEAM AXIS ADJUSTMENT
MODE.
- When the ECM transfers to BEAM AXIS
ADJUSTMENT MODE, the buzzer sounds
for 1 second.
- Confirm the current value of the laser beam
(The default reading is 6.3 when the reflector
is out of range).
- Move the reflector either to right or left by 100
mm (19.69 in.) and check that the value
changes.
NOTICE:
When the values do not change, it is
possible that the direction of the laser radar
sensor is greatly off target, and that the
laser radar sensor is aiming at something
different. Check the installation condition of
the laser radar sensor.
- Return the reflector to the original position and
read the current angle.
Standard
HINT:
If the vehicle dimensions are correct, the
values should be within the above standard
value range. If any value is out of the range,
check the installation condition of the bumper
reinforcement, etc. as it can not be adjusted
automatically.
- Turn the headlight dimmer switch to the TAIL
position.
- Beam axis adjustment will be performed
automatically.
- When the adjustment is completed, the
UPPER/ LOWER SIDE and RIGHT/LEFT SIDE
indicators show 0 and the system beeps for 10
seconds. During this time, UPPER and
LOWER flash alternately on the screen, and
LEFT and RIGHT flash alternately on the
screen.
NOTICE:
Adjustment values are calculated and then
stored in the laser sensor. As the system is
not controlled mechanically, the same value
as before is displayed to adjust the beam
axis.
INSTALLATION
1. INSTALL LASER SENSOR
NOTICE:
Do not install the laser sensor if it has been
damaged or received some sort of shock.
