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.

360(I) Front Sheet Metal, Cowl PartsThe main function of the front sheet metal and the cowl parts is forming an engine compartment to supply the
engine and accessories with a protective cover and to absorb the most energy when vehicle encounters
frontal impaction, protecting mud from being splashed by the front wheels, and meeting the requirements of
body design in appearance. It is mainly composed of front cross member assembly, LH/RH front mud guard
and front side member assembly, engine hood front support plate assembly, hood lock bracket assembly,
cowl assembly, cowl upper assembly.
1. Front Cross Member Assembly
The front cross member assembly is mainly composed of the front cross member welding sub-assembly,
front cross member bottom plate assembly, LH/RH side member end plate by welding them together, and its
dismantle diagram as shown in the Figure 5-2.
2. Lh/Rh Front Mudguard And Front Side Member Assembly
LH/RH front mud guard and front side member assembly is mainly composed of LH/RH front mudguards
and LH/RH side members by welding them together.
It is mainly used to mount some mounting brackets such as the engine LH/RH side suspension bracket, LH/
RH front suspension shock absorber bracket, etc. and to mount the LH/RH front fenders.
3. Engine Hood Front Support Plate Assembly
Engine hood front support plate is mainly composed of LH/RH headlamp mounting bracket assembly, hood
front support plate sub-assembly, and LH/RH front support plate reinforcement, by welding them together.
Engine hood front support plate assembly is used to mount radiator, engine hood lock, radiator grille, front
bumper, and headlamp.
4. Engine Hood Lock Bracket Assembly
Engine hood lock bracket assembly is used to mount the engine hood lock, also to strengthen the intensity and
rigidity of the front body by connecting the engine hood front support plate and front cross member.
5. Cowl Assembly
Cowl assembly is mainly composed of cowl inner and outer plate assembly and cowl lower cross member, by
welding them together.
Cowl assembly and front floor, LH/RH front mud guard (LH/RH front pillar), cowl upper baffle is welded
together, which forms a framework with great torsional strength. It generates great resistance to lateral
impact and rolled deformation.
Cowl inner and outer plate assembly is sandwich structure. 3mm of asphalt plate lies in the interlayer, which
is to cut off the noise and heat generated from the engine.
