INSPECTION
FUNCTION AND OPERATION PRICIPLE
Camshaft Position Sensor (CMPS) is a hall sensor and detects the camshaft position by using a hall element. It is
related with Crankshaft Position Sensor (CKPS) and detects the piston position of each cylinder which the CKPS can't
detect. The two CMPS are installed on engine head cover of bank 1 and 2 and uses a target wheel installed on the
camshaft. This sensor has a hall - effect IC which output voltage changes when magnetic field is made on the IC with
current flow.

WHEEL ALIGNMENT
When using commercially available computerized four wheel alignment equipment (caster, camber, toe) to inspect the
front wheel alignment, always position the car on a level surface with the front wheels facing straight ahead.
Prior to inspection, make sure that the front suspension and steering system are in normal operating condition and
that the wheels and tires face straight ahead and the tires are inflated to the specified pressure.
TOE
Toe is a measurement of how much the front of the wheels are turned in or out from the straight- ahead position.
Item Description
A - B < 0 Positive (+) toe (toe in)
A - B > 0 Negative ( - ) toe (toe out)
When the wheels are turned in toward the front of the vehicle, toe is positive (+) (toe in). When the wheels are turned
out toward the front of the vehicle, toe is negative(- ) (toe out). Toe is measured in degrees, from side to side, and
totaled.
[FRONT]
Toe- in(B - A or angle a+b) is adjusted by turning the tie rod turnbuckles. Toe- in on the left front wheel can be reduced
by turning the tie rod toward the rear of the car. Toe- in change is adjusted by turning the tie rods for the right and left
heels simultaneously at the same amount as follows.
Standard value :
Toe- in (B- A) mm (in) : 0 ± 2 (0 ± 0.0787)
a. Toe- in adjustment should be made by turning the right and left tie rods at the same amount.
b. When adjusting toe - in, loosen the outer bellows clip to prevent twisting the bellows.
c. After the adjustment, tighten the tie rod end lock nuts firmly and reinstall the bellows clip.
d. Adjust each toe - in to be the range of ±1mm.
Tie rod(A) Specified torque Nm (kgf.m, lb - ft) :
70 ~ 80 (7 ~ 8, 50.6 ~ 57.8)

a.During air bleeding, replenish the fluid supply so that the level never falls below the lower position of the
filter.
b. If air bleeding is done while the vehicle is idling, the air will be broken up and absorbed into the fluid. Be
sure to do the bleeding only while cranking.
c. Reinstall the fuel pump fuse, and start the engine(idling).
d. Turn the steering wheel to the left and the right until there are no air bubbles in the oil reservoir.
Do not hold the steering wheel turned all the way to either side for more than ten seconds.
e. Confirm that the fluid is not milky, and that the level is up to the position specified on the level gauge.
f. Confirm that there is little change in the surface o the fluid when the steering wheel is turned left and right.
a. If the surface of the fluid changes considerably, air bleeding should be done again.
b. If the fluid level rises suddenly when the engine is stopped, it indicates that there is still air in the
system.
c. If there is air in the system, a jingling noise may be heard from the pump and the control valve
may also produce unusual noises. Air in the system will shorten the life of the pump and other
parts.
OIL PUMP PRESSURE TEST (OIL PUMP RELIEF PRESSURE)
1.Disconnect the pressure hose from the oil pump. Connect the special tool between the oil pump and pressure hose
as illustrated.
2. Bleed the air, and then start the engine and turn the steering wheel several times so that the fluid temperature
rises to approximately 50°C (122°F).
3. Set the engine speed to 1,000 rpm.
4. Close the shut- off valve of the special tool and measure the fluid pressure to confirm that it is within the range.
standard vaule :
Relief pressure: 90 +3/- 2 kgf/cm²
Don’t keep the shut- off valve on the pressure gauge closed for longer than seconds.

b. HECU
During ABS operation, the brake pedal may vibrate or may not be able to be depressed. Such phenomena are
due to intermittent changes in hydraulic pressure inside the brake line to prevent the wheels from locking and is
not an abnormality.
DETECTING CONDITION
Trouble Symptoms Possible Cause
Brake operation varies depending on driving conditions and road
surface conditions, so diagnosis can be difficult.However if a normal
DTC is displayed, check the following probable cause. When the
problem is still occurring, replace the ABS control module. a.
Inoperative power source circuit
b. Inoperative wheel speed sensor circuit
c. Inoperative hydraulic circuit for leakage
d. Inoperative HECU
INSPECTION PROCEDURES
DTC INSPECTION
1. Connect the Scan Tool with the data link connector and turn the ignition switch ON.
2. Verify that the system is operating to specifications.
Is the system operating to specifications ?
▶ Check the power source circuit.
▶ Erase the DTC and recheck using Scan Tool.
CHECK THE POWER SOURCE CIRCUIT.
1. Disconnect the connector from the ABS control module.
2. Turn the ignition switch ON, measure the voltage between terminal 18 of the ABS control module harness side
connector and body ground.
Specification: approximately B+
Is the voltage within specification?
▶ Check the ground circuit.
▶ Check the harness or connector between the fuse (10A) in the engine compartment junction block and the ABS
control module. Repair if necessary.

2.Compare the change of the output voltage of the wheel speed sensor to the normal change of the output voltage
as shown below.
a.V_low : 0.44 V ~ 0.63 V
b. V_high : 0.885 V ~ 1.26 V
c. Frequency range : 1~2,500 Hz

REMOVAL
1.Remove the rear wheel speed sensor mounting bolt (A).
2.Remove the rear seat side pad then disconnect the rear wheel speed sensor connector (A).
INSPECTION
1.Measure the output voltage between the terminal of the wheel speed sensor and the body ground.
In order to protect the wheel speed sensor, when measuring output voltage, a 75Ω resistor must be used as
shown.
2. Compare the change of the output voltage of the wheel speed sensor to the normal change of the output voltage
as shown below.

description of ESP
Optimum driving safety now has a name : ESP, the Electronic Stability Control.
ESP recognizes critical driving conditions, such as panic reactions in dangerous situations, and stabilizes the vehicle
by wheel- individual braking and engine control intervention with no needfor actuating the brake or the gas pedal.
ESP adds a further function known as Active Yaw Control (AYC) to the ABS, TCS, EBD and ESP functions. Whereas
the ABS/TCS function controls wheel slip during braking and acceleration and, thus, mainly intervenes in the
longitudinal dynamics of the vehicle, active yaw control stabilizes the vehicle about its vertical axis.
This is achieved by wheel individual brake intervention and adaptation of the momentary engine torque with no need
for any action to be taken by the driver.
ESC essentially consists of three assemblies : the sensors, the electronic control unit and the actuators.
Of course, the stability control feature works under all driving and operating conditions. Under certain driving
conditions, the ABS/TCS function can be activated simultaneously with the ESP function in response to a command
by the driver.
In the event of a failure of the stability control function, the basic safety function, ABS, is still maintained.
DESCRIPTION OF ESP CONTROL
ESP system includes ABS/EBD, TCS and AYC (Active yaw control) function.
ABS/EBD function : The ECU changes the active sensor signal (current shift) coming from the four wheel sensors to
the square waveform.By using the input of above signals, the ECU calculates the vehicle speed and the acceleration
& deceleration of the four wheels.And, the ECU judges whether the ABS/EBD should be actuated or not.
TCS function prevents the wheel slip of drive direction by adding the brake pressure and engine torque reduction via
CAN communication.TCS function uses the wheel speed sensor signal to determine the wheel slip as far as ABS
function.
AYC function prevents unstable maneuver of the vehicle. To determine the vehicle maneuver, AYC function uses the
maneuver sensor signals(Yaw Rate Sensor, Lateral Acceleration Sensor, Steering Wheel Angle Sensor).If vehicle
maneuver is unstable (Over Steer or Under Steer), AYC function applies the brake pressure on certain wheel, and
send engine torque reduction signal by CAN.
After the key - on, the ECU continually diagnoses the system failure. (self- diagnosis)If the system failure is detected,
the ECU informs driver of the system failure through the BRAKE/ABS/ESP warning lamp. (fail- safe warning)
