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 toBL-10, "
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.

OUTLINE
Power door lock systems with super lock function provides a higher anti-theft performance than conventional
power door lock systems. The super lock system is controlled by BCM (Body Control Module).
Pressing LOCK button on key fob once will lock all doors and activate super lock simultaneously.
When super lock is set, all doors cannot be opened from inside.
Pressing UNLOCK button once on key fob will unlock driver side door (unlock all doors if anti-hijack system is
disabled and during this state, super lock is still active). Second press on the UNLOCK button within 5 second
from the first will unlock all doors and release super lock simultaneously.
Functions Available By Operating the Door Lock/Unlock Switch
lOperating the door lock/unlock switch in the control panel will activate all doors actuator to lock or unlock.
If any doors are opened (except the driver side) during operating the door lock/unlock switch in lock direc-
tion, the door lock actuators will not response. Unlock via the interior door handles and door lock/unlock
switch is always possible.
lOperating the door lock/unlock switch to “LOCK” will lock the vehicle even while driver side door is
opened.
OPERATION
Set Super Lock Conditions
lWhen all these following conditions are met, BCM receives lock signal from key fob.
–All doors are closed.
–Key is out of the ignition key cylinder.
Release Super Lock Conditions
lBCM unit receives a valid unlock signal from key fob.
lIgnition switch is turned ON (door lock/unlock switch will remain its state, super lock is released).
NOTE:
Door lock/unlock switch is incapable of overriding super lock.

CAN Communication System DescriptionEIS00DX1
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitEIS00DX2
Refer toLAN-23, "CAN COMMUNICATION".

LOAD SENSING VALVE
Inspection
EFS006A8
INSPECTION
1. With the vehicle in unladen condition, a person should sit in driver's seat at the rear. Then he/she should
get out of car gently. (This is to stabilize suspension deflection.)
NOTE:
“Unladen condition”: with full coolant, lubricant, 6 to 8 litters of fuel, spare tyre, jack, and hand tools
loaded.
2. Press load sensing valve against stopper bolt. Check if center-to-center length “L” between adjusting ref-
erence hole and reference pin is as specified below.
lIf measurement is outside the standard, perform following;
loosen mounting bolt of sensor spring bracket. By moving
sensor spring bracket, adjust so that the length “L” comes into
specified range.
3. Connect brake fluid pressure tester (special service tool) to
bleed valves of front caliper and rear wheel cylinder.
4. Bleed air from brake fluid pressure tester (special service tool).
5. With brake pedal depressed, check brake fluid pressure at front
caliper and rear wheel cylinder. The respective measurements
should be as specified in the table below.
6. Under condition of step 2 above, adjust rear shaft weight with
weights to obtain 143.9-146.9 mm (5.67-5.78 in) as length
“L”. Then, check brake fluid pressure as described in step 5
above. If measurements are outside the standards, replace load
sensing valve main body.
