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 the facts and conditions when the noise occurs and any
customer's comments; refer toSE-8, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that exist when the noise occurs.
lThe 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).
lIf there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.
lAfter 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.
lSqueak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping
lCreak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
lRattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
lKnock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
lTick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
lThump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.
lBuzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
lOften the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.
lWeather conditions, especially humidity and temperature, may have a great effect on noise level.

TROUBLE DIAGNOSIS
14. Repair the system as outlined by the “Repair order” in “Intermittent Malfunction Diagnostic Code Chart”,
that corresponds to the self-diagnostic result. For replacement procedure of component parts, refer to the
Removal and Installation procedure for the appropriate component.
15. Go toSRS-24, "
DIAGNOSTIC PROCEDURE 3", for final checking.

4. Connect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.
5. The lamp on the right side of the tool, marked “deployment tool
power”, should glow green, not red.
6. Press the button on the deployment tool. The left side lamp on
the tool, marked “air bag connector voltage”, will illuminate and
the air bag module or seat belt pre-tensioner will deploy.
CAUTION:
Deploy only one air bag module or seat belt pre-tensioner at
atime.
DISPOSING OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER
Deployed air bag modules and seat belt pre-tensioners are very hot. Before disposing of air bag module or
seat belt pre-tensioner, wait at least 30 minutes or 10 minutes, respectively. Seal them in a plastic bag before
disposal.
CAUTION:
lNever apply water to a deployed air bag module or seat belt
pre-tensioner.
lBe sure to wear gloves when handling a deployed air bag
module or seat belt pre-tensioner.
lNo poisonous gas is produced upon air bag module
deployment. However, be careful not to inhale gas since it
irritates the throat and can cause choking.
lDo not disassemble air bag module or seat belt pre-
tensioner.
lAir bag modules and seat belt pre-tensioners cannot be
reused.
lWash your hands thoroughly after finishing work.

FRONT WIPER AND WASHER SYSTEM
COMBINATION SWITCH READING FUNCTION
Description
lBCM reads combination switch status, and controls related systems such as headlamps and wipers,
according to the results.
lBCM reads information for a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 input terminals (INPUT 1-5).
Operation Description
lBCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
turn.
lIf any (1 or more) switches are turned ON, the circuit of output terminals (OUTPUT 1-5) and input termi-
nals (INPUT 1-5) becomes active.
lAt this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of the input terminal (INPUT 1-5) corresponding to that switch changes, the interface in the BCM
detects a voltage change, and the BCM determines that the switch is ON.
