Noise InspectionINFOID:0000000005931317
The vehicle itself can be a source of noise if noise
prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.

Occurrence condition Possible cause
Occurs only when engine is ON. A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed.
Ignition components
A whistling noise occurs while the engine speed is
high. A booming noise occurs while the engine is
running and the lighting switch is ON. Generator
Noise only occurs when various
electrical components are oper-
ating. A cracking or snapping sound occurs with the op-
eration of various switches.
Relay malfunction, radio malfunction
The noise occurs when various motors are operat-
ing. • Motor case ground
• Motor
The noise occurs constantly, not just under certain conditions. • Rear defogger coil malfunction
• Open circuit in printed heater
A cracking or snapping sound occurs while the vehicle is being driven, especially when
it is vibrating excessively. • Ground wire of body parts.
• Ground due to improper part installation
• Wiring connections or a short circuit

BCM (BODY CONTROL MODULE)
BCM (BODY CONTROL MODULE)
System DescriptionINFOID:0000000005929255
BCM (body control module) controls the operation of various electrical units installed on the vehicle.
BCM FUNCTION
BCM has a combination switch reading function for reading the operation of combination switches (light, wiper,
washer, turn signal) in addition to the function for cont rolling the operation of various electrical components.
Also, it functions as an interface that receives signal s from the front air control, and sends signals to ECM
using CAN communication.
COMBINATION SWITCH READING FUNCTION
1. Description • BCM reads combination switch (light, wiper) status, and controls various electrical components accord-
ing to the results.
• BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
and five input terminals (INPUT 1-5).
2. Operation description • BCM activates transistors of output terminals (OUTPU T 1-5) periodically and allows current to flow in
turn.
• If any (1 or more) of the switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input ter- minals (INPUT 1-5) becomes active.
• At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When
voltage of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects
voltage change and BCM determines that switch is ON.
3. BCM - Operation table of combination switch • BCM reads operation status of combination switch by the combination shown in the following table.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Work FlowINFOID:0000000005929273
CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interv iew to document the facts and conditions when the noise occurs and any
customer's comments; refer to BL-11, "
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 descr iption 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, 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.
• 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 bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
• Often 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.
• Weather conditions, especially humidity and temperature, 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 you confirm the repair.

Operation Description
• When the Intelligent Key unit detects that each request sw
itch is pressed, it starts the outside key antenna
and inside key antenna corresponding to the pressed request switch and sends the request signal to the
Intelligent Key. And then, make sure that the Intelligent Key is near door.
• If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and sends the key ID signal to the Intelligent Key unit.
• Intelligent Key unit receives the key ID signal and compares it with the registered key ID.
• If the key ID check result is OK, the Intelligent Ke y unit sends the door lock/unlock request signal to BCM
(Body control module) via CAN communication line.
• Intelligent Key unit sends the door lock/unlock signal and sounds Intelligent Key warning buzzer (lock: 2 times, unlock: 1 time) at the same time.
• When BCM receives the door lock/unlock signal, it oper ates door lock actuator and flashes the hazard warn-
ing lamp (lock: 2 times, unlock: 1 time) at the same time as reminder.
Operation Condition
If the following conditions are not satisfied, door lock/unlock operations are not performed even if the request
switch is operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as Key IDs are different.
Outside Key Antenna Detection Area
The outside key antenna detection area of door lock/unloc k function is in the range of approximately 80 cm
(31.50 in) surrounding the request switch (driver side, passenger side and back door or trunk area).
Hazard and Buzzer Reminder
When all doors and trunk (sedan) are locked or unlocked by each request switch, Intelligent Key\
unit sends
hazard request signal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder and Intelligent Key unit sounds Intelligent Key warning
buzzer(s) as a reminder.
Operating function of hazard and buzzer reminder
* : Sedan only
Auto Door Lock Function
When all doors and trunk (sedan) are locked, ignition knob sw itch is OFF (when ignition switch is not pressed)
and key switch is OFF (when mechanical key is out of ignition key cylinder), all doors are unlocked with each
request switch.
When Intelligent Key unit does not receive the following signals within 1 minute, all doors are locked.
• Door switch is ON (door is opened)
• Trunk lamp switch (sedan) is ON (trunk is opened)
• Door lock signal from Intelligent Key button
• Ignition knob switch is ON (ignition switch is pressed)
• Key switch is ON (mechanical key is inserted in ignition key cylinder)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
117, "CONSULT-III Application Item".
