Driver/Vehicle Information Display: Description and Operation

INTEGRATED DISPLAY SYSTEM

System Description

A/C AND AV SWITCH SYSTEM
Refer to Owner's Manual for A/C and AV switch operating instructions.
Using the A/C and AV switch at the center of the instrument panel, the controls of the following systems are centralized:
- Integrated display system (Drive computer, setting screen, etc.)

- Audio system

PRECAUTION OF LCD MONITOR
- In order to use LED for backlight of a display, by interior temperature, brightness may change. In low temperature, the refreshing rate of the picture also becomes low because of the low response of the LCD monitor. When the interior becomes warm, however, the LCD recovers the normal display.
- Backlight sometimes flickers or darkens according to the wearing out of LCD and the number of times switched ON and OFF. In this case, display unit should be replaced. (Exchange only of backlight is impossible.)

When ignition switch is in ON or START position, power is supplied
- through 10 A fuse [No. 12, located in fuse block (J/B)]
- to unified meter and A/C amp. terminal 22 and
- to display unit terminal 3.

Ground is supplied
- to unified meter and A/C amp. terminals 29, 30
- to display unit terminals 6 and 15 and
- to A/C and AV switch terminal 5
- through body grounds M35, M45 and M85.

Ground is supplied through the case of the audio unit.

DRIVE COMPUTER
Refer to Owner's Manual for drive computer operating instructions.

TRIP Switch




When "TRIP" switch is pressed, display TRIP screen. As TRIP information, it indicates journey time (TIME), trip odometer (DIST), average vehicle speed (AVG).

Pressing "TRIP" switch once cycles display from TRIP 1->TRIP 2->Display OFF->TRIP 1.

"TIME"
- Journey time indication is performed by reset or battery connection.
- When pushing "TRIP RESET" or "TRIP" switch more than approximately 1.5 seconds, journey time will be reset.
- If journey time is reset, journey distance and average speed will be reset at the same time.

"DIST"
- Trip odometer indication is performed by vehicle speed signal.
- When pushing "TRIP RESET" or "TRIP" switch more than approximately 1.5 seconds, driving distance will be reset.
- If trip odometer is reset, journey time and average speed will be reset at the same time.

"AVG"
- Average speed indication is performed by running distance and running time.
- Indication will be renewed every 30 seconds.
- When pushing "TRIP RESET" or "TRIP" switch more than approximately 1.5 seconds, average speed will be reset.
- After reset operation, the displays shows "*" for 30 seconds.

FUEL ECON Switch




When "FUEL ECON" switch is pressed, display FUEL ECON screen. As FUEL ECON information, it indicates average fuel consumption (AVG), distance to empty (DTE).

Pressing "FUEL ECON" switch once cycles display from FUEL ECON->Display OFF->FUEL ECON.

"AVG" (Average Fuel Consumption)
- Average fuel consumption indication is performed by fuel consumption signal and vehicle speed signal after system is reset.
- Indication will be renewed every 30 seconds.
- When pushing "TRIP RESET" or "FUEL ECON" switch more than approximately 1.5 seconds, average fuel economy will be reset.
- After reset operation, the display shows " *.* " until the vehicle is driven 500 m (1,600 ft.) or 30 seconds has passed.

"DTE" (Distance to Empty)
- Distance to empty receives via CAN communication and indicates values calculated by meter.
- Display range is max 999 miles (max 999 km).
- If low-fuel WARNING is received from meter via CAN communication, distance to empty indication will be "*".
- Indication will be renewed every 30 seconds.

MAINT Switch (Maintenance Switch)
- When "MAINT" switch is pressed, display vehicle information screen. As vehicle information, it indicates engine oil, tire rotation, tire pressure.
- Pressing "MAINT" switch once cycles display from engine oil->tire rotation->tire pressure->display OFF->engine oil.

Engine Oil and Tire Rotation




- Operating the joystick left/right, replace distance can be set.
- When journey distance is the same as replace distance, alert is displayed. (SERVICE ALERT setting is ON.)
- Selected replace distance is 0 - 7,500 miles (0 - 12,000 km) in increments of 500 mile (800 km).
- Press and hold "TRIP RESET or MAINT" switch for 1.5 seconds or longer, reset present journey distance.
- During driving, cannot change settings.

Tire Pressure




- Tire pressure signal is received from BCM through CAN communication line.
- Tire pressure is displayed.
- When FLAT TIRE signal is received from BCM, "FLAT TIRE" is displayed.




E/M SWITCH

SETTING SCREEN
- Setting of electric status can be changed by A/C and AV switch. The signal is sent to BCM through display unit to change vehicle electric system setting.
- Display unit is communicating with driver seat control unit.
- Pressing "SETTING" switch once cycles display from DISPLAY->LANGUAGE->BEEP SET->SERVICE ALERT->PERSONALIZED SETTINGS MENU->DISPLAY OFF->DISPLAY.
- Using the joystick, setting of each item will become possible.




Adjustable Vehicle Status

D/N SCREEN




- Turning on "DAY/NIGHT" switch, DAY MODE or NIGHT MODE is indicated for present mode.
- If press "DAY/NIGHT" again when display adjustment luminance, change DAY-NIGHT (NIGHT-DAY) mode (screen of adjustment luminance).




As shown:
- Press "PREV" or not operate for 10 sec. when displayed screen of adjustment luminance, back to default screen (same mode).
- Can adjust luminance by "DISP" switch. Light can be adjusted by pressing "+" (bright) or "-" (dark).
- Adjustment range is a 12 stage (MIN to MAX) and default set value is 10 (DAY) and 4 (NIGHT).

WARNING INDICATIONS
When BCM receives warning signal from some control units or sensors, then combination meter warning lamp is illuminated.




Then BCM sends warning signal to display unit warning indications on the screen.

AV COMMUNICATION LINE
Display unit is controlled by the following unit with AV communication line.
- A/C and AV switch

CAN Communication System Description
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.

CAN Communication Unit
Refer to "INFORMATION BUS".
