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.
b.When the multifunction switch is not in postion headlamps turned on or autolight
c. 20 mn after the driver door is open
d. 20mn after IGN leaves the positions RUN to ACC or OFF
e. If IPM receives RKE "LOCK" command two times
3. Escort function enables only "Head Lamp Low Beam", so Park/Tail lamp should be turned off when driver door is
opened at key out (Battery Saver function).

Interior Lighting Functions
Room Lamps
1.The room lamps are can be controlled manually using the 3 - state (ON, DOOR, OFF) switch or by the Rear Area
Module (RAM). A main switch, located to the left of the steering wheel, is used as a master control switch. The
operating logic of the lamps will vary based on the position of the main switch ON, DOOR, or OFF).
2. Working conditions
a. The functioning depends on the key position in the key cylinder (OFF, ACC, RUN or START)
b. When the key goes in RUN or START position while the room lamps are decaying, then the room lamps are
turned off immediately.
c. When the Ignition key position is RUN or START and the last door is closed then the room lamps are OFF.
d. If the room lamps have been activated using the RKE UNLOCK function, and the ignition switch is turned to the
RUN or START position, the room lamps will be immediately turned OFF..
e. If the Ignition sw status is in RUN or START and Unlock information occurs, then the room lamp status is not
changed.
f. When the system enters to ARM WAIT mode by Remote Key or Mechanical cylinder lock switches the Room
lamp should be turned off immediately.
g. If there is RKE Lock signal at any door open, all doors should be locked first and wait for the all door close. No
action is taken while the Open Door status is OPEN and the doors are locked. Then when Open Door status
changes from OPEN to CLOSE, Room lamps will be OFF immediately.
h. The 30sec timer does not depend on the key reminder status.
i. If the main switch is changed to ON from DOOR after 20minute lamp OFF, all the lamps are turned ON.
j. If the Open Door status changes from OPEN to CLOSE (all doors close) when ignition switch is on RUN
position, room lamps and door courtesy lamps should turn off immediately (Do not decay off).
k. After 20minute Room Lamp OFF at door open, Room lamps are turned ON again when:
a. One of the door open switch's status changes. (Open to Close or Close to Open)
b. Ignition key is in RUN or START Position.
c. Receiving an UNLOCK event while a door is open and Main Room Lamp Switch is in the DOOR position.
l. For the room lamps, when the 20m timer is running and any of the side doors is opened the timer is restarted.
