Cautions in Removing Battery Terminal and AV Control UnitINFOID:0000000009951289
CAUTION:
Remove battery terminal and AV control unit after a lapse of 30 seconds or more after turning the igni-
tion switch OFF.
NOTE:
After the ignition switch is turned OFF, the AV cont rol unit continues operating for approximately 30 seconds.
Therefore, data corruption may occur if battery voltage is cut off within 30 seconds.
General PrecautionsINFOID:0000000009462995
• Do not operate the engine for an extended period of time without proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any inflam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or ot her enclosed area, be sure to prop-
erly ventilate the area before working with hazardous materials.
Do not smoke while working on the vehicle.
• Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent t he vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
These operations should be done on a level surface.
• When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the c onditions 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 GW-9, "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.

Component Description
A/C auto amp. A/C auto amp. controls front automatic air conditioning system by inputting and calculating signals
from each sensor and each switch.
A/C Compressor Vaporized refrigerant is drawn into the A/C compressor from the evaporator, where it is compressed
to a high pressure, high temperature vapor. The hot, compressed vapor is then discharged to the con-
denser.
A/C switch assembly The A/C switch assembly controls the operation of the A/C and heating system based on inputs from
the temperature control knob, the mode switches, the blower control dial, the ambient temperature
sensor, the intake sensor, and inputs received from the ECM across the CAN. Diagnosis of the A/C
switch assembly can be performed using the CONSULT. There is no self-diagnostic feature available.
Air mix door motor LH The air mix door controls the mix of hot or cold air that enters the ventilation system. It is controlled
by the A/C auto amp. based on the position of the temperature dial. The air mix door motor LH re-
ceives position commands from the A/C auto amp. and reports actual door position back via an LCU
(Local Control Unit) installed inside the motor. Commands and responses are sent across the LIN (Lo-
cal Interconnect Network) to each motor simultaneously, with each motor having its own unique ad-
dress, thereby only responding to requests sent to its specific address. The LCU reads the door
position from a Position Balanced Resistor (PBR), also part of the motor, and returns that information
to the A/C auto amp. The LCU switches the polarity of the circuits connected to the DC motor to drive
the motor forward or backward as requested by the A/C auto amp. If the air mix door moves to a po-
sition less than 5% or more than 95% of its expected or allowed positions, the A/C auto amp. will set
a DTC.

Air mix door motor RH The air mix door controls the mix of hot or cold air that enters the ventilation system. It is controlled
by the A/C auto amp. based on the position of the temperature dial. The air mix door motor RH re-
ceives position commands from the A/C auto amp. and reports actual door position back via an LCU
(Local Control Unit) installed inside the motor. Commands and responses are sent across the LIN (Lo-
cal Interconnect Network) to each motor simultaneously, with each motor having its own unique ad-
dress, thereby only responding to requests sent to its specific address. The LCU reads the door
position from a Position Balanced Resistor (PBR), also part of the motor, and returns that information
to the A/C auto amp. The LCU switches the polarity of the circuits connected to the DC motor to drive
the motor forward or backward as requested by the A/C auto amp. If the air mix door moves to a po-
sition less than 5% or more than 95% of its expected or allowed positions, the A/C auto amp. will set
a DTC.
Ambient sensor The ambient sensor measures the temperature of the air surrounding the vehicle. The sensor uses a
thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor
decreases as temperature increases.
BCM The BCM receives the fan ON and A/C ON signals from the A/C auto amp. and sends a compressor
ON request to the ECM.
Blower motor The blower motor varies the speed at which the air flows through the ventilation system.
ECM The ECM sends a compressor ON request to the IPDM E/R based on the status of engine operation
and load as well as refrigerant pressure information. If all the conditions are met for A/C operation,
the ECM transmits the compressor ON request to the IPDM E/R. The ECM shares the refrigerant
pressure sensor signal, engine RPM, and engine coolant temperature with the A/C auto amp. via
CAN communication line.
Front blower motor relay The front blower motor relay controls the flow of current to fuse 17 and 27 in the Fuse Block (J/B).
The relay is connected directly to ground, and is energized when the ignition switch is in the ON or
START position.
Fuse Block (J/B) Located in the passenger compartment, behind the left lower IP, the Fuse Block (J/B) contains the
front blower motor relay and several fuses required for the air conditioner control system.
Intake door motor The intake door motor controls the position of the intake door. Fresh air is allowed to enter the cabin
in one position, and recirculated inside air is allowed to enter in the other position. At times the A/C
auto amp. may command partial fresh or recirculation based on evaporator or coolant temperatures.
The intake door motor receives position commands from the A/C auto amp. and reports actual door
position back via an LCU (Local Control Unit) installed inside the motor. Commands and responses
are sent across the LIN (Local Interconnect Network) to each motor simultaneously, with each motor
having its own unique address, thereby only responding to requests sent to its specific address. The
LCU reads the door position from a Position Balanced Resistor (PBR), also part of the motor, and re-
turns that information to the A/C auto amp. The LCU switches the polarity of the circuits connected to
the DC motor to drive the motor forward or backward as requested by the A/C auto amp. If the recir-
culation door moves to a position less than 5% or more than 95% of its expected or allowed positions,
the A/C auto amp. will set a DTC.
Intake sensor The intake sensor measures the temperature of the front evaporator fins. The sensor uses a ther-
mistor which is sensitive to the change in temperature. The electrical resistance of the thermistor de-
creases as temperature increases.
In-vehicle sensor In-vehicle sensor measures temperature of intake air that flows through aspirator to passenger room.
The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resis-
tance of the thermistor decreases as temperature increases.
IPDM E/R Refer to PCS-6, "RELAY CONTROL SYSTEM : System Description"
.
Mode door motor The mode door controls the direction the conditioned air passes through the ventilation system.
Through a series of levers and gears, the mode door controls the defrost door, the foot door, and the
vent door. There are 5 preset positions: VENT, B/L, FOOT, D/F, and DEF. The FOOT position can be
set to allow some airflow through to the defroster vent, or to completely block the defroster vent using
the CONSULT. The mode door motor receives position commands from the A/C auto amp. and re-
ports actual door position back via an LCU (Local Control Unit) installed inside the motor. Commands
and responses are sent across the LIN (Local Interconnect Network) to each motor simultaneously,
with each motor having its own unique address, thereby only responding to requests sent to its spe-
cific address. The LCU reads the door position from a Position Balanced Resistor (PBR), also part of
the motor, and returns that information to the A/C auto amp. The LCU switches the polarity of the cir-
cuits connected to the DC motor to drive the motor forward or backward as requested by the A/C auto
amp. The mode door has 5 expected positions and, therefore, can set up to 5 DTCs if the expected
position is not reported back to the A/C auto amp.
