< BASIC INSPECTION >[ICC]
LASER BEAM AIMING ADJUSTMENT
 Turn the up-down direction adjusting screw slowly. The value change on display is slower than actual move-
ment of the ICC sensor. Wait for 2 seconds every ti me the up-down direction adjusting screw is turned half a
rotation.
 Turning the up-down direction adjusting screw (A) clockwise (C)
directs the laser beam downward. The laser beam directs upward
when turning up-down direction adjusting screw counterclockwise
(B).
CAUTION:
Be careful not to cover the ICC sensor body window with a
hand or the other part of body of worker during adjustment.
>> GO TO 3.
3.LASER BEAM AIMING CONFIRMATION
1. When the “U/D CORRECT” value becomes ±4 or less, check that no value greater than ±4 appears when
the vehicle is left with no load on the ICC s ensor (hand removed) for at least 2 seconds.
2. When “COMPLETED THE VERTICAL AIMING OF LASER BEAM” display appears, touch “END”.
CAUTION:
Always check that the value of “U/D CORRECT” remains ±4 or less when the ICC sensor is left
alone for at least 2 seconds.
3. Check that “ADJUSTING AUTOMATIC HORIZONTAL LASER BEAM AIMING” is displayed and wait for a
short period of time. (The maximum: Approx 10 seconds).
4. Check that “Normally Completed” is displayed, and select “End” to end “LASER BEAM ADJUST”.
CAUTION:
Once “LASER BEAM ADJUST” is started with CONS ULT-III, always continue the work until the
horizontal laser beam aiming ad justment is completed successfully. If the job is stopped midway,
the laser beam aiming is not adjust ed and the ICC system cannot operate.

Work FlowINFOID:0000000006425595
CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document t he facts and conditions when the noise occurs and any of
customer's comments; refer to DLK-213, "
Diagnostic Worksheet". This information is necessary to duplicate
the conditions that exist when the noise occurs.
 The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain all the facts and conditions that exist when the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, perform a diagnosis and repair the noise that the customer is
concerned about. This can be accomplished by performing a cruise test on the vehicle with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
 Squeak – (Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping
 Creak – (Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
 Rattle – (Like shaking a baby rattle)
Rattle characteristics include the fast repeated contac t/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
 Knock – (Like a knock on a door)
Knock characteristics include hollow sounding/someti mes repeating/often brought on by driver action.
 Tick – (Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loose components/can be caused by driver
action or road conditions.
 Thump – (Heavy, muffled knock noise) Thump characteristics include softer k nock/dead sound often brought on by activity.
 Buzz – (Like a bumblebee)
Buzz characteristics include high frequency rattle/firm contact.
 Often the degree of acceptable noise level will vary depending up on the person. A noise that a technician may judge as acceptable may be very irritating to the customer.
 Weather conditions, especially humidity and temperat ure, may have a great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or lo cation of the noise. This information can be used to
duplicate the same conditions when the repair is reconfirmed.
