2007 KIA CARNIVAL ESP

2007 > 2.7L V6 GASOLINE >
DESCRIPTION
1.The yaw - rate & lateral G sensor is applied for the ESP system.
2. The yaw - rate is the angular velocity, when a vehicle turns a corner, and the lateral G is the acceleration to move a
vehicle out of the way when cornering.
3. The sensor is located in the crash pad lower floor on vehicle.

DESCRIPTION
GENERAL DATA
The steering angle speed sensor detects the angle of the steering wheel in order to which direction a user chooses.
MEASUREING PRINCIPLE
A non contact, analog angle sensor carrying out absolute measuring by the use of the Anisotropic - Magneto- Resistive
effect (AMR).Measuring of the absolute angle by means of a toothed measuring gear with magnetic properties in
combination with different ratios. Corresponding AMR elements that change their electrical resistance according to the
magnetic field direction detect the angle position of the measuring gears.A micro- controller decodes the measured
voltage signals after A/D converting with the help of a mathematical function. Output of the digital angle value and
velocity via CAN- interface.

CIRCUIT DIAGRAM( STEERING WHEEL SPEED ANGLE SENSOR)
STEERING ANGLE SENSOR (SAS) calibration
1.PURPOSE OF calibration
a. On vehicle control, an ESP analyzes the intention of the driver.
b. An ESP recognizes a steering angle which a driver rotates through the steering angle sensor.

c.A steering angle sensor used in ESP adjusts 0° setting of steering wheel through K- line or CAN
communication.
2. STEERING ANGLE SENSOR (SAS) CALIBRATION METHOD
(1) Align the wheel to the straight line. (steering wheel < ± 5° )
ex) Perform the wheel alignment first.
Align the wheel to the straight line.
A driver moves the vehicle to the front and back about 5 meters twice or three times.
(2) Connect Scan tool to the vehicle.
(3) Select Brake system.
(4) Select Steering angle sensor(SAS) calibration.
(5)Perform the Steering angle sensor(SAS) calibration.
(6)Perform the procedure continuously.

HANDLING WIRES AND HARNESSES
1.Secure wires and wire harnesses to the frame with their respective wire ties at the designated locations.
2. Remove clips carefully; don't damage their locks (A).
3.Slip pliers (A) under the clip base and through the hole at an angle, and then squeeze the expansion tabs to
release the clip.
4.After installing harness clips, make sure the harness doesn't interfere with any moving parts.
5. Keep wire harnesses away from exhaust pipes and other hot parts, from sharp edges of brackets and holes, and
from exposed screws and bolts.
6. Seat grommets in their grooves properly (A). Do not leave grommets distorted (B).

Stop Lamps Function
1.Necessary conditions to switch ON the stop lamps:
a. Pushing on the brake pedal.
2. Necessary conditions to switch OFF the stop lamps:
a. Releasing the brake pedal.
3. Functional diagram
Auto Light Function
1.The Auto light function is active when the Head lamp switch is positioned to 'Auto' and the Key is in RUN position.
The auto light sensor is powered on the status ACC, START and RUN of the key position. Based on the Auto light
sensor values corresponding to the exterior brightness level, it controls automatically the lighting of the Park and tail
lamps or / and the Head lamps Low Beam depending on the country.
2. Auto light Sensor detection table
Mode Tail Lamps
Head Lamps Low Beam
Lux (Lux) Voltage(V) Lux (Lux)Voltage(V)
ON < 24 ± 5.2 <1.77 ± 0.08V Same as Tail lamps
OFF > 48 ± 10.5 > 3.47 ± 0.1V Same as Tail lamps
Drl Function
1.The Auto DRL function operates the Head lamps High Beam at 50% of full illumination.
The park and tail are managed by the auto light sensor.
The Auto DRL function is active if:
a. The ignition switch is on RUN position
b. The engine is running.
c. The Park brake switch is OFF.
2. The DRL function is inactive when one of above conditions is released.
When the DRL function is active, the Head lamps High Beam can't be turned ON, except for the Flash To Pass
activation.
