LDW SYSTEM OPERATION

  1. The Lane Departure Warning (LDW) system warns the driver when the vehicle is traveling close to either the left or the right of the traveling lane.
  2. The system monitors lane markers of the traveling lane using the LDW camera unit. When the LDW camera unit detects that the vehicle is traveling close to either the left or the right of the traveling lane, the LDW indicator lamp flashes and a chime sounds to alert the driver. NOTE: When activating turn signal, LDW system does not give a warning to the lane marker on the turn signal side.
  3. The LDW system can be turned on or off by pushing the LDW switch. When the system is on, the LDW system ON indicator illuminates.
  4. The LDW system has an automatic mode and manual mode.

In the automatic mode

  1. LDW system automatically turns on, when the ignition switch is turned to the ON position.
  2. LDW system ON indicator located on the LDW switch illuminates, indicating that the system is on.
  3. To cancel LDW system, push the LDW switch to turn off LDW system ON indicator.
  4. To turn on the system, push LDW switch again.

In the manual mode

  1. LDW system is still off when the ignition switch is turned to the ON position.
  2. The LDW switch must be pushed to turn on the system.

To the change modes

  1. Push and hold LDW switch for more than 4 seconds, when LDW system ON indicator is off.
  2. Then LDW chime sounds and blinking of LDW system ON indicator informs that the mode change is completed. Temporary disabled status at high temperature If the vehicle is parked in direct sunlight under high temperature conditions [approximately over 104°F (40°C)] and then started, the LDW system may sound a chime and cancel automatically. Then LDW system ON indicator will blink. When the interior temperature is reduced, the system will resume to operate automatically and the LDW system ON indicator illuminates.

CONSULT-II FUNCTION (LDW)

Refer to " CONSULT-II START PROCEDURE ".

Touch "WORK SUPPORT" on "SELECT DIAG MODE" screen.

  1. Touch "SELF-DIAG RESULTS" on "SELECT DIAG MODE" screen.
  2. See the displayed result of self-diagnosis.
  1. Touch "DATA MONITOR" on "SELECT DIAG MODE" screen.
  2. Touch any of "ALL SIGNALS" and "SELECTION FROM MENU" on selection screen.
  3. Touch "START".
  4. Display the data monitor.
  5. If necessary, touch "COPY" in turn, and print data.

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

  1. This electronic compass is able to display 8 primary directions: N, NE, E, SE, S, SW, W, NW.
  2. The inside mirror switch (2) is used to operate the compass and automatic anti-glare system.
PressCompass is turned ON/OFF
Press and hold (for 3 - 6 sec.)Automatic anti-glare system turns ON/OFF
Press and hold (for 6 - 9 sec.)Compass display turns to zone variation change mode
Press and hold (for more than 9 sec.)Compass display turns to calibration mode

SYSTEM DESCRIPTION

Note. For further details of the compass and automatic anti-glare system, refer to Owner's service information

  1. All standard compasses determine direction relative to Magnetic North; however, this electronic compass is designed to display direction relative to True North.
  2. The difference between Magnetic North and True North varies from place to place across the surface of the earth.
  3. This electronic compass must be "told" approximately where it is on the earth's surface so that the Magnetic North reading can be properly converted into a True North display.
  4. To tell the electronic compass where it's at, the earth is separated into numbered "Zone Variances". The Zone Variance number in which the compass is to function must be entered into this electronic compass.
  5. Each zone is magnetically about 4.2° wide. Typically, anything under 22.5° total zone change is not noticed on the electronic compass display. However, over 22.5°, a reading may be off by one or more primary directions.
  6. On long trips, a vehicle may leave its original zone and enter one or more new zones. Generally, you do not need to reset the compass zone if you travel between 3 or 4 zones, such as business travel or vacation. The typical driver will not notice any difference on the display within 3 or 4 zones. However, if the vehicle is "permanently" moved to a new location, it is recommended that the compass zone be reset.
  1. The rear view monitor is equipped to check the rearward of the vehicle with display when A/T selector lever is in reverse position.
  2. The lines of vehicle sides and the distance from the rear end of the vehicle are provided on display as a guide. It allows the driver to know the distance between the vehicle and a rearward object, and the width of the vehicle much easier.

REAR VIEW CAMERA OPERATION

When A/T selector lever is reverse position, power is supplied

  1. through back-up lamp relay terminal 2
  2. to TCM terminal 7.

Then back-up lamp relay is energized

  1. from back-up lamp relay terminal 5
  2. to rear view camera control unit terminal 4.

Then, rear view camera control unit is sent camera ON signal

  1. through rear view camera control unit terminal 8
  2. to rear view camera terminal 1.

An image taken by rear view camera is sent

  1. through rear view camera terminals 3 and 4
  2. to rear view camera control unit terminals 10 and 9.

Then an image is sent

  1. through rear view camera control unit terminals 12 and 14
  2. to the display terminals 15 and 16.

An image of rear view will be projected on the display.

Refer to " CONSULT-II START PROCEDURE ".

  1. Touch "DATA MONITOR" on "SELECT DIAG MODE" screen.
  2. Touch either "SELCT GUIDELINE PATTERN" or "ADJ GUIDELINE POSITION" on the "WORK SUPPORT" screen.
