< PRECAUTION >
PRECAUTIONS
 Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
 If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
 To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
 Dispose of drained oil or the solvent used for cleaning parts in an
appropriate manner.
 Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray
and possibly a fire.
 Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
 Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
 Replace inner and outer races of tapered roller bearings and needle bearings as a set.
 Arrange the disassembled parts in accordance with their assembled locations and sequence.
 Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
 After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
 Use only the fluids and lubricants specified in this manual.
 Use approved bonding agent, sealants or their equivalents when required.
 Use hand tools, power tools (disassembly only) and recommended
special tools where specified for safe and efficient service repairs.
 When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
 Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)

 Do not use the vehicle tie downs to free a vehicle stuck in sand, snow, mud, etc. Never tow the vehi-
cle using the vehicle tie downs or recovery hooks.
 Always pull the cable straight out from the front of the vehicle. Never pull on the hook at an angle.
 Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or
cooling systems.
 Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
REAR
WARNING:
 Rear hook is not available.
AUTOMATIC TRANSMISSION
To tow a vehicle equipped with an automatic transmission, an appropriate vehicle dolly MUST be placed under
the towed vehicle's drive wheels. Always follow the dolly manufacture's recommendations when using their
product.
If the vehicle is stuck in sand, snow, mud, etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control System.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.
Shift back and forth between R (reverse) and D (drive).
Apply the accelerator as little as possible to maintain the rocking motion.
Release the accelerator pedal before shifting between R and D.
Do not spin the tires above 35 mph (55 km/h).
5. If the vehicle can not be freed after a few tries, contact a professional towing service to remove the vehi-
cle.

AUTOMATIC AIR CONDITIONER SYSTEM
AIR CONDITIONER LAN CONTROL SYSTEM
The LAN (Local Area Network) system consists of the A/C auto amp., the mode door motor, the air mix door
motors and the intake door motor.
A configuration of these components is as shown in the figure below.
SYSTEM CONSTRUCTION
A small network exists between the A/C auto amp., the mode door motor, the air mix door motor and the intake
door motor. The A/C auto amp. and motors are connected by data transmission lines and motor power supply
lines. The LAN network is built through the ground circuits of each door motor.
Addresses, motor opening angle signals, motor stop signals and error checking messages are all transmitted
through the data transmission lines connecting the A/C auto amp. and each door motor.
The following functions are contained in LCUs built into the mode door motor, the air mix door motors and the
intake door motor.

 Decision (A/C auto amp. indicated value and motor opening angle comparison)
Operation
The A/C auto amp. receives data from each of the sensors. The A/C auto amp. sends mode door, the air mix
door and the intake door opening angle data to the mode door motor LCU, the air mix door motor LCUs and
the intake door motor LCU.
The mode door motor, the air mix door motors and the intake door motor read their respective signals accord-
ing to the address signal. Opening angle indication signals received from the A/C auto amp. and each of the
motor position sensors is compared by the LCUs in each door motor with the existing decision and opening
angles. Next, HOT/COLD, DEF/VENT, OPEN/SHUT or FRE/REC operation is selected. The new selection
data is returned to the A/C auto amp.
Transmission Data and Transmission Order
A/C auto amp. data is transmitted consecutively to each of the door motors following the form as shown in the
figure below.
START: Initial compulsory signal is sent to each of the door motors.
ADDRESS: Data sent from the A/C auto amp. is selected according to data-based decisions made by the mode door
motor, the air mix door motors and the intake door motor.
 If the addresses are identical, the opening angle data and error check signals are received by the door motor
LCUs. The LCUs then make the appropriate error decision. If the opening angle data has no error, door con-
trol begins.
 If an error exists, the received data is rejected and the corrected data received. Finally, door control is based
upon the corrected opening angle data.
OPENING ANGLE:
 Data that shows the indicated door opening angle of each door motor.
ERROR CHECK: In this procedure, transmitted and received data is checked for errors. Error data is then compiled. The error
check prevents corrupted data from being used by the mode door motor, the air mix door motors and the
intake door motor. Error data can be related to the following symptoms.
- Malfunction of electrical frequency
- Poor electrical connections
- Signal leakage from transmission lines
- Signal level fluctuation

 At the end of each transmission, a stop operation, in-operation, or internal malfunction message is delivered
to the A/C auto amp. This completes one data transmission and control cycle.
