Steering Angle Sensor

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.

Steering Angle Sensor

2007 > 2.7L V6 GASOLINE >
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.

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.

(7)The procedure is finished. Push the "ESC" key.
(8)Scanner OFF.
(9) Remove the scanner from the vehicle.
(10) Confirm the Steering angle sensor(SAS) calibration as driving the vehicle.(turn left once, turn right once)

9.Installation is the reverse of removal.
CRASH PAD REPLACEMENT
a.When prying with a flat- tipped screwdriver, wrap itwith protective tape, and apply protective tapearound the
related parts, to prevent damage.
b. Put on gloves to protect your hands.
1. Remove the following items.
a. Front seat.
b. Cluster facia panel, cluster.
c. Audio assembly.
d. Glove box.
e. Side cover, center under cover.
f. Front pillar trim.
2. Remove the photo sensor (C), speaker connector (B).
3. Disconnect the passenger`s air bag connector (A).
Loosen the bolt and nut, then remove the crash pad (D).
4. Installation is the reverse of removal.
a.Make sure the crash pad fits onto the guide pins correctly.
b. Before tightening the bolts, make sure the crash pad wire harnesses are not pinched.
c. Make sure the connectors are plugged in properly, and the antenna lead is connected properly.
d. Enter the anti- theft code for the radio, then enter.

MODULE INTRODUCTION
FAM/IPM/RAM consists of a power board and an electronic board. The power board contains circuit protection devices
and switching devices. The electronic board uses Intelligent Power Switching (IPS) for HS/LS load control, logic
functions and CAN/K- Line communication. The power board and electronic board are connected with pin blocks for
the Front Area Module (FAM) and VCD (Variable Connection Displacement) for the In- Panel Module (IPM) and the
Rear Area Module (RAM).
