1-32 HEATER AND AIR CONDITIONING
F06R300013








Direct charging with a manifold gauge charging
station method.
Handling the charging valve handle when installing refrigerant
container.
1) Before attaching the charge valve to the refrigerant
container, turn the charge valve handle counterclockwise
until the needle is fully retracted.
2) Turn the plate nut counterclockwise until it reaches its
highest position relative to the charge valve.
3) Install the charge valve onto the refrigerant container.
4) Turn the plate nut clockwise and connect the center hose of
the manifold gauge to the charge valve.
5) Tighten the plate nut sufficiently by hand. Then turn the
charge valve handle clockwise to lower the needle and bore
a hole in the refrigerant container.
6) Turn the charge valve handle counterclockwise to raise the
needle. The refrigerant in the refrigerant container is
charged into the air conditioning system by the operation of
the manifold gauge.





Be absolutely sure not to reuse the emptied

HEATER AND AIR CONDITIONING 1-33
refrigerant container.


1) Make sure the evacuation process is correctly completed.
2) Connect the center-hose of the manifold gauge to the
refrigerant container.






Turn the charge valve handle counterclockwise to purge
to the charging line and purge any air exiting in the
center-hose of the manifold gauge.
3) Open the low-pressure hand valve and charge the
refrigerant about 200 g (0.44 lbs.).






Make sure the high-pressure hand valve is closed.






Avoid charging the refrigerant by turning the refrigerant
container upside down.
4) Close the low-pressure hand valve of the manifold gauge.






Check to ensure that the degree of pressure does not
change.
5) Check the refrigerant leaks by using a HFC-134a leak
detector.






If a leak occurs, repair the leak connection, and start all
over again from the first step of evacuation.
6) If no leaks are found, open the low-pressure hand valve of
the manifold gauge. Then continue charging refrigerant to
the system.






When charging the system becomes difficult:
(1) Run the engine at Idling and close the all vehicle
doors.
(2) A/C switch is "ON".
(3) Set the fan control knob (fan switch) to its highest
position.
(4) Set air soure selector lever to “RECIRC”



WARNING
BE ABSOLUTELY SURE NOT TO OPEN THE HIGH-
PRESSURE HAND VALVE. SHOULD THE HIGH-
PRESSURE HAND VALVE BE OPENED, THE HIGH-
PRESSURE REFRIGERANT GAS WOULD FLOW
BACKWARD, AND THIS MAY CAUSE THE REFRIGERANT
CONTAINER TO BURST.
7) When the refrigerant container is emptied, use the following
procedure to replace it with a new refrigerant container.
(1) Close the low-pressure hand valve.
(2) Raise the needle upward and remove the charge valve.
(3) Reinstall the charge valve to the new refrigerant
container.
(4) Purge any air existing in the center hose of the manifold
gauge.
8) Charge the system to the specified amount and then close
the low-pressure hand valve.

11A-6 IMMOBILIZER SYSTEM

What happens without proper transponder
operation?
One of the function of transponder is to deactivate or
activate starter function. lf the proper transponder is not
used, starter cannot be operated. Because starter rela
y
stays off, cranking engine is not possible.
After the starter relay is activated, transponder signal
triggers to let lCU calculate by transponder address
signal and immobilizer algorithm.
When the result matches with necessary condition, it
makes injector power source be activated.
If transponder does not send correct signal, lCU and
ECM do not activate injector system on.
Therefore the vehicle cannot be operated.
No proper transponder is available, what
should be done for the system?
When any proper transponder is not available, a new
transponder should be programmed. Up to 5
transponders can be provided with a scan tool (Tech-2)
and by proper procedure.
In addition to the absence of proper transponder, it ma
y
happen particular secret code to the particular vehicle is
missing. ln this case, the secret code must be provided
by your organization.
Otherwise transponder cannot be programmed in an
y
way.
lf the essential for a scan tool (Tech-2) for programming
and proper software for Tech-2 are not available, there
is no permanent way to fix system. Temporary replace
with new ECM, new ICU and new transponder without
any secret code can make the system be deactivated,
but it does not last long. Such a replacement does not
solve any condition. Even after replacement, the system
is activated automatically in short time and then no
operation of the vehicle can be made in any way.
Tech-2 should be provided in your organization.
Caution to the operation
lf an attempt is made to start the engine while the
immobilizer system is activated, the check engine lamp
flashes and the engine will not start.
Summary of operation
Switch on: Set the ignition and starter switch to OFF.
(Activate)
Switch off: Set the ignition and starter switch to ON b
y
using the transponder key. (Deactivate)

What your organization should provide for
your customer





Car Pass

For a new owner, your dealership must hand Car Pass
card, which has identification numbers of new owner's
vehicle immobilizer system. This information is ver
y
important in case of repair or lost of transponder.
The followings are necessary items provided by you
r
responsibility.
1)
Car pass with identification for a new owner
2)
Blank car pass card when it is for reissue
3)
Instruction to dealers how to use car pass card






Security code management

Your organization must keep security codes for all
vehicles as confidential data. Once the security codes
are lost, anybody who have the security code can
access immobilizer system. Your organization has
responsibility of any missing vehicles caused by stolen
security code.






Essential tool (Scan tool : Tech-2)

Your dealership must have Tech-2, and Tech-2 updated
software for immobilizer system.

FRONT ALIGNMENT 3A-3

Inspection
Before making any adjustments affecting caster, camber or
toe-in, the following front end inspection should be made.
1. Inspect the tires for proper inflation pressure. Refer to
Main Data and Specifications in Wheel and Tire System
section.
2. Make sure that the vehicle is unlade condition (Withno
passenger or loading).
3. Make sure that the spare tire is installed at the normal
position.
4. Inspect the front wheel bearings for proper adjustment.
Refer to Front Hub and Disc Overhaul in Suspension
section.
5. Inspect the ball joints and tie rod ends. If excessive
looseness is noted, correct before adjusting. Refer to
Steering Linkage in this section.
6. Inspect the wheel and tires for run-out. Refer to Wheel
Replacement in Wheel and Tire System section.
7. Inspect the trim height. If not within specifications, the
correction must be made before adjusting caster.
8. Inspect the steering unit for looseness at the frame.
9. Inspect shock absorbers for leaks or any noticeable noise.
Refer to Shock Absorber in Suspension section.
10. Inspect the control arms or stabilizer bar attachment fo
r
looseness. Refer to Suspension section.
11. Inspect the front end alignment using alignment equipment.
Follow the manufacturer’s instructions.
12. Park the vehicle on a level surface.

3B-6 POWER-ASSISTED STEERING SYSTEM

Steering Column


This illustration is based on the RHD model.
RTW43BLF000101
WARNING: TO AVOID DEPLOYMENT WHEN
TROUBLE-SHOOTING THE SRS SYSTEM, DO NOT
USE ELECTRICAL TEST EQUIPMENT, SUCH AS
BATTERY-POWERED OR A/C-POWERED VOLT-
METER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN SPECIFIED
IN THIS MANUAL. DO NOT USE A NON-POWERED
PROBE-TYPE TESTER.
INSTRUCTION IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PERSONAL
INJURY MAY RESULT.
When servicing a vehicle equipped with Supplemental
Restraint System, pay close attention to all WARNINGS
and CAUTIONS.
For detailed explanation about SRS, refer to Restraints
section.
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch and lock are mounted
conveniently on the column.
3. With the column mounted lock, the ignition and
steering operation can be locked to prevent theft o
f
the vehicle.
The column can be disassembled and reassembled.
However, to insure the energy absorbing action, use
only the specified screws, bolts and nuts as designated,
and tighten them to the specified torque.
Handle the column with care when it is removed from
the vehicle. A sharp blow on the end of steering shaft o
r
shift lever, or dropping the assembly could shear o
r
loosen the fastenens that maintain column rigidity.
