291IV. ABS Operation Inspection1. Check the Wheel Speed Sensor Output Voltage
1Check whether the clearance between the wheel speed sensor and the ring gear is within the specification
For front wheel standard value, refer to "Front Wheel Sensor Installation Drawing"
For rear wheel standard value, refer to "Rear Wheel Sensor Installation Drawing"
3Jack up the wheel and release the manual brake
2Remove the ABS wire harness, measure at the wire harness connector
4Rotate the wheel at the speed of 1/2 turn/second, and use the multimeter or oscilloscope to measure the
output voltage
Terminal 1-2
Terminal 19-20
Terminal 5-6
Terminal 22-23
Output Voltage
zWhen use the multimeter to measure
For front wheel, refer to "Front Wheel Sensor Drawing".
For rear wheel, refer to "Rear Wheel Sensor Drawing".
zWhen use the oscilloscope to measure
For front wheel, refer to the related standard.
For rear wheel, refer to the related standard.
5The fact that the output voltage is not within the above range may result from the following causes:
zExcessive clearance between the sensor and the ring gear.
zSensor fault.
zCheck the sensor resistance£¨1.0 - 1.3k¦¸£©.
zSelect the 4 points on the ring gear to check the clearance (ring gear distortion) between the ring
gear and the wheel speed sensor.
2.Check the Hydraulic Control Unit (HCU).
1Jack up the vehicle, make sure the wheel can rotate freely.
2Release the manual brake.
3Turn the ignition switch to ON after connecting the scan meter, do not start the engine this time.
4Refer to the HCU Diagnosis for inspection.
Note: when connecting or removing the scan meter, the ignition switch must be turned to OFF.

292Section 3 Removal and InstallationI.Precautions for Removal1. Use the scan meter to locate the fault causes before proceeding to service.
2. wipe the surface clean with the cleaning agent without mineral oil before service; be careful to keep it
clean during service, only the lint-free cloth can be used to wipe the removed parts.
3. Only the original spare part can be used, and the package of the new spare part shall not be removed until
the installation.
4. Return liquid pump motor and the HCU is a type of integral structure and can not be separated.
5. When the system is opened, do not use compressed air or move the vehicle.
6. Use proper plug to clog each hydraulic outlet as soon as the ABS assembly is removed.
7. Remove other components that may interfere.
8. Please use the DOT 4 brake fluid, do not use the mineral oil.
9. Use the brake fluid to immerse the seal and the O ring, do not use the engine oil or brake grease.
10. After service, check the regular brake system and ABS brake function for normal and reliable operation.
11. Check all hydraulic pipe union for leakage.II. HECU Removal1. Turn off the ignition switch and disconnect the battery negative ground cable.
2. Remove the wire connector from the ABS HECU assembly.
3. Depress the brake pedal >60mm and hold it with the pedal retainer to close the master cylinder center
valve so that the brake fluid will not flow out from the outlet when the system is opened.
4. Put a clean cushion under the hydraulic regulator.
5. Remove the brake pipe (A, B) on the HCU connected to the master cylinder and place the mark, then
use a plug to clog the outlet immediately.
6. Remove the brake fluid pipe(1-4) leading to the wheels, then use a plug to clog the outlet immediately.
7. Remove the nut attaching the HECU to the bracket.

297Part IV Air Conditioner and Inside &
Outside TrimChapter 1 A/C SystemA/C system consists of refrigerating and heating system. The Refrigeration system mainly comprises
compressor, condenser and evaporator. The refrigerant circulation absorbs the heat in the air and discharge
the vapour to lower the temperature in and dehumidify the compartment. The heating system is mainly
composed of heat exchanger and heater. It heats the compartment throught the heat exchanger by heating
the air with the heat from the cooling water in the engine. The control of air temperature, humidity and
velocity of flow in the compartment is realized by independent or joint working of heating and Refrigeration
system.Section 1 The Structure & Working Principle of Refrigeration SystemThe structure of Refrigeration system is shown in Figure 1.

Refrigeration system uses vapor compressing refrigeration cycle, comprising the compressor, condenser,
pressure relief valve, evaporator, blower , expansion valve, receiver/drier and pipe.
It's working principle is as shown in the Figure 1. The compressor (1) sucks in the refrigerant gas in the

299Section 2 Heating SystemHeating system uses mixed temperature adjustment which controls both cold and hot air and is featured in
outstanding temperature adjustment performance. The cold and hot air can be completely mixed at each
outlet and achieve continuous temperature adjustment. The air duct arrangement on the instrument panel is
shown in Figure 2. The air flow channel system is shown in Figure 3.I. Heating System Parameter and StructureHeating system uses water heating structure which uses the engine coolant as the heat source, leads the the
coolant into the heating radiator installed in the vehicle compartment and has the interior or exterior air blow
across the radiator with the blower to increase its temperature. The system consists of the blower assembly,
heating control assembly and heater assembly.Figure 2 Heating Duct ArrangementInside and Outside Air Switch Door Outdoor AirIndoor AirDefoggerIntermidiate outletHeaterBlower MotorEvaporatorAir Mix DoorHeating RadiatorFigure 3 Air Flow Channel System Illustration
