ABS Braking
•ABS operation is available at all vehicle speeds above 20 km/h. If a wheel locking tendency is detected during
a brake application, the brake system enters the ABS mode. During ABS braking, hydraulic pressure in the four
wheel circuits is modulated to prevent any wheel from locking. Each wheel circuit is designed with a set of
electric solenoids to allow modulation. The system can build and release pressure at each wheel, depending on
signals generated by the wheel speed sensors at each wheel and received at the ABS Module.
• There are a few performance characteristics of the ABS that may at first seem abnormal, but in fact are nor-
mal. These characteristics are described below.
If the electrical system malfunctions, the Fail-Safe function is activated, the ABS becomes inoperative and
the ABS warning lamp turns on.
During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is normal.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or snow-covered (fresh, deep snow) roads.

Antilock Brake System (ABS) Bleeding Procedure
ABS Bleeding Information
WARNING!
When bleeding the brake system, wear safety glasses. A clear bleed tube must be attached to the bleeder
screws and submerged in a clear container filled partially. Direct the flow of brake fluid away from yourself and
the painted surfaces of the vehicle. Brake fluid at high pressure may come out of the bleeder screws when
opened.
CAUTION:
Before removing the master cylinder cap, wipe it clean to prevent dirt and other foreign matter
from dropping into the master cylinder reservoir. Use brake fluid or an equivalent from a fresh,
tightly sealed container. Brake fluid must conform to DOT 4 specifications.
NOTE :
During the brake bleeding procedure, be sure the brake fluid level remains close to theMAXlevel in the master
cylinder fluid reservoir. Check the fluid level periodically during the bleeding procedure and add brake fluid as
required.
NOTE :
Do not pump the brake pedal at any time while having a bleeder screw open during the bleeding process. This will
only increase the amount of air in the system and make additional bleeding necessary. Do not allow the master
cylinder reservoir to run out of brake fluid while bleeding the system. An empty reservoir will allow additional air into
the brake system. Check the fluid level frequently and add fluid as needed. The following wheel circuit sequence for
bleeding the brake hydraulic system should be used to ensure adequate removal of all trapped air from the hydraulic
system.
ABS Bleeding Instructions
When bleeding the ABS system, the following bleeding sequence must be followed to ensure complete and adequate
bleeding:
1. Make sure all hydraulic fluid lines are installed and properly torqued.
2. Connect the X-431 scan tool to the diagnostics connector.
3. Using the scan tool, check to make sure the ABS module does not have any fault codes stored. If it does, clear them.
4. Bleed the base brake system (See Manual Brake Bleeding in Section 12 Brake).
NOTE :
Pressure bleeding is recommended to bleed the base brake system to ensure all air is removed from the brake
system.
5. Using the scan tool, access ABS bleedingfunction. Follow the instructions displayed. When finished, discon-
nect the scan tool and proceed.
6. Bleed the base brake system a second time. Check brake fluid level in the reservoir periodically to prevent emptying, causing air to enter the hydraulic system.
7. Fill the master cylinder fluid reservoir to the MAXlevel.
8. Test drive the vehicle to be sure the brakes are operating correctly and that the brake pedal does not feel spongy.

Outside fresh air enters the vehicle through the cowl top opening at the base of the windshield, and passes through
a plenum chamber to the HVAC housing. Air flow can be adjusted by the blower motor speed switch on the A/C
heater control panel. The fresh air then travels through the evaporator and the heater core then out into the vehicle
through the side and floor vents. It is important to keep the air intake openings clear of debris such as leaf particles
which are small enough to pass through the cowl plenum screen and can accumulate within the HVAC housing. The
A/C compressor can be engaged by pressing the A/C (snowflake) button on the A/C-Heater control panel. It will
automatically engage when the mode control is set in any Mix to Defrost position. This will remove heat and humidity
from the air before it is directed through or around the heater core. The mode control on the A/C-Heater control panel
is used to direct the conditioned air to the selected system outlets.

Description
All models are equipped with a common HVAC housing assembly that combines A/C and heating capabilities into a
single unit mounted within the passenger compartment. The HVAC housing assembly consists of three separate
housings:
•HVAC housing — The HVAC housing is mounted to the dash panel behind the instrument panel and contains
the A/C evaporator. The HVAC housing has mounting provisions for the air inlet housing, blower motor and the
air distribution housing.
• Air distribution housing — The air distribution housing is mounted to the rear of the HVAC housing and con-
tains the heater core, blend-air and mode-air doors and door linkage.
• Air inlet housing — The air inlet housing is mounted to the passenger side end of the HVAC housing. The air
inlet housing contains the recirculation-air door and actuator.
Operation
The A/C system is designed for the use of a non-CFC, R-134a refrigerant and uses an A/C evaporator to cool and
dehumidify the incoming air prior to blending it with the heated air. Temperature control determines the discharge air
temperature by operating the temperature control cable, which moves the blend-air door. This allows an almost
immediate control of the output air temperature of the system. The mode door cable operates the mode-air doors
which direct the flow of the conditioned air out the various air outlets, depending on the mode selected. When
equipped with A/C, the recirculation door actuator operates the recirculation-air door which closes off the fresh air
intake and recirculates the air already inside the vehicle. The electric recirculation door actuator and the blower motor
are connected to the vehicle electrical system by the instrument panel wire harness. The blower motor controls the
velocity of air flowing through the HVAC housing assembly by spinning the blower wheel within the HVAC housing at
the selected speed by use of the blower motor resistor, which is around the blower motor.
The air distribution housing must be removed from the HVAC housing and disassembled for service of the blend-air
and mode-air doors. The air inlet housing must be removed from the HVAC housing and disassembled for service of
the recirculation-air door. The HVAC housing must be removed from the vehicle and disassembled for service of the
A/C evaporator.

Description
The A/C refrigerant lines and pipes are used to carry the refrigerant between the various A/C system components.
Any kinks or sharp bends in the refrigerant lines and hoses will reduce the capacity of the entire A/C system and can
reduce the flow of refrigerant within the system.
Operation
High pressure is produced in a refrigerant system when the A/C compressor is operating. Extreme care must be
exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free. It is a good
practice to inspect all flexible hose refrigerant lines at least once a year to make sure they are in good condition and
properly routed. Depending on vehicle, model and market application, refrigerant lines are connected to each other or
other A/C system components with block-type or quick-connect type fittings. To ensure the integrity of the refrigerant
system, O-rings and/or gaskets may be used to seal the refrigerant system connections. The refrigerant lines and
hoses cannot be repaired and must be replaced if leaking or damaged.
WARNING!
The A/C system contains refrigerant under high pressure. Repairs should only be performed by qualified service
personnel. Serious or fatal injury may result from improper service procedures.
If accidental A/C system discharge occurs, ventilate the work area before resuming service. Large amounts of
refrigerant released in a closed work area will displace the oxygen and cause suffocation and serious or fatal
injury.
CAUTION:
Never add R-12 to a refrigerant system designed to use R-134a. Do not use R-12 equipment or
parts on an R-134a A/C system. These refrigerants are not compatible and damage to the A/C sys-
tem will result.
CAUTION:
Never use R-12 refrigerant oil in an A/C system designed to use R-134a refrigerant oil. These refrig-
erant oils are not compatible and damage to the A/C system will result.
CAUTION:
Do not run the engine with a vacuum pump in operation or with a vacuum present within the A/C
system. Failure to follow this caution will result in serious A/C compressor damage.
CAUTION:
Do not overcharge the refrigerant system. Overcharging will cause excessive compressor head
pressure and can cause compressor noise and A/C system failure.

3. Open both the suction and discharge valves, then open the charge valve to allow the refrigerant to flow into the system.
4. When the transfer of refrigerant has stopped, close both the suction and discharge valves.
5. If all of the refrigerant charge did not transfer from the dispensing device, open all of the windows in the vehicle and set the heating-A/C system controls so that the A/C compressor is operating and the blower motor is running
at its lowest speed setting. Run the engine at a steady high idle (about 2000 RPM).
6. Open the low-pressure valve to allow the remaining refrigerant to transfer to the refrigerant system.
WARNING!
Take care not to open the discharge (high pressure) valve at this time. Failure to follow this warning could result
in possible personal injury or death.
7. Disconnect the refrigerant recovery/recycling station from the refrigerant system service ports.
8. Reinstall the caps onto the refrigerant system service ports.
Compressor
Description
Vehicles equipped with the 1.6L & 1.8L & 2.0L engine use a SD7V16 clutch-less compressor. The 2.4L equipped
vehicles use a V5 clutch-less compressor. The compressor is a variable displacement compressor. The largest dis-
placement is 161.3 ml/r, displacement range of 5% to 100%.
CAUTION:
DONT run the engine with a vacuum pump in operation or with a vacuum present within the A/C
system. Failure to follow this caution will result in serious A/C compressor damage.
NOTE :
The compressor drive hub and the pulley and bearing assembly cannot be serviced separately from the A/C com-
pressor. In the event of drive hub or pulley and bearing assembly damage or failure, the A/C compressor, drive hub
and pulley and bearing must be replaced as an assembly.
Operation
The A/C compressor is controlled by the Engine Control Module (ECM), depending on engine application. The ECM
calculates compressor displacement required by A/C system load and demand by monitoring vehicle speed, A/C high
side pressure, engine speed, evaporator temperature, accelerator pedal position, ambient temperature and A/C-
Heater request signals. The ECM then sends a pulse width modulated signal to the A/C compressor control solenoid
to increase or decrease refrigerant flow through an orifice located within the compressor housing. The amount of
refrigerant allowed to pass through the orifice in the compressor determines the head pressure which controls the
angle of the swash plate, which in turn, determines the amount of compressor displacement. When there is no
demand for A/C, the swashplate is adjusted to nearly a zero degree angle, which removes compressor torque drag
from the engine.
NOTE :
The A/C compressor cannot be repaired and it must be replaced if found inoperative or damaged. If an internal fail-
ure of the A/C compressor has occurred, the A/C accumulator and the A/C liquid line must also be replaced.

Description
Available occupant restraints for this vehicle include both active and passive types. Active restraints are those which
require the vehicle occupants to take some action to employ, such as fastening a seat belt; while passive restraints
require no action by the vehicle occupants to be employed.
Active Restraints
•Front Seat Belts
• Rear Seat Belts
Passive Restraints
• Driver Airbag
• Passenger Airbag
• Seat Belt Tensioners
Operation
Active Restraints
The primary passenger restraints are the seat belts. Seat belts are referred to as an active restraint because the
vehicle occupants are required to physically fasten and properly adjust these restraints in order to benefit from them.
Passive Restraints
The passive restraints are referred to as a supplemental restraint system because they were designed and are
intended to enhance the protection for the occupants of the vehicle only when used in conjunction with the seat belts.
They are referred to as passive restraints because the vehicle occupants are not required to do anything to make
them operate; however, the vehicle occupants must be wearing their seat belts in order to obtain the maximum safety
benefit from the supplemental restraint system.
The supplemental restraint system electrical circuits are continuously monitored and controlled by a microprocessor
and software contained within the Restraints Control Module (RCM). An airbag indicator in the instrument cluster
illuminates for about seven seconds as a bulb test each time the ignition switch is turned to the ON or START posi-
tions. Following the bulb test, the airbag indicator is turned ON or OFF by the RCM to indicate the status of the
supplemental restraint system. If the airbag indicator comes ON at any time other than during the bulb test, it indi-
cates that there is a problem in the supplemental restraint system electrical circuits. Such a problem may cause
airbags not to deploy when required, or to deploy when not required.
Deployment of the supplemental restraints depends upon the angle and severity of an impact. When an impact is
severe enough, the microprocessor in the RCM signals the inflator of the appropriate airbag units to deploy their
airbag cushions. The front seat belt tensioners are provided with a deployment signal by the RCM in conjunction with
the front airbags.
