ELECTRO-LUMINESCENT METER

To increase desirability and visibility of the meter, an electro-luminescent meter is used on some models.

1. Red LEDs are used for meter rings and needles illumination.
2. The brightness of the meter display area can be properly adjusted to meet various conditions.
3. An indicator that illuminates when the lighting switch is turned to the next position from OFF is provided.

GENERAL

1. The speedometer system is an electrical type that uses electric signals from the ABS or vehicle dynamics control (VDC) control module.
2. Since the system does not use mechanical components such as rotating cable, there are no opportunities of occurring such problems as meter needle vibration and cable disconnection. Also, it does not constitute any means of mechanical noise transmission.
3. The odometer and trip meter readings appear on a liquid crystal display (LCD).
4. At the trip meter display, the illumination level and the following trouble information (abnormality of various control modules, communication system, vehicle speed signals, etc.) are shown in addition to the trip meter reading.

TACHOMETER

The tachometer drive circuit is connected to the engine speed sensing circuit in the engine control module.

When the engine speed increases or decreases, the voltage of the circuit also increases or decreases, changing the magnetic force of the tachometer drive coil.

The tachometer needle then moves in accordance with change in the engine speed.

WATER TEMPERATURE GAUGE

1. Water temperature signals are generated at the engine coolant temperature sensor on the engine, and after converted into digital signals, these signals are sent via the body integrated unit to the combination meter.
2. The resistance of the engine coolant temperature sensor changes according to the engine coolant temperature. Therefore, the signals sent to the water temperature gauge also changes according to the engine coolant temperature. As the change in signals causes the magnetic force of the step motor to change, the gauge needle moves according to the engine coolant temperature.
3. When the coolant is at a normal operating temperature of approx. 85 to 100°C (158 to 212°F), the gauge needle stays in the middle of the indication range as shown below.

Scheme 7

1. The fuel gauge unit consists of a float and a potentiometer whose resistance varies depending on movement of the float. It is located inside the fuel tank and forms an integral part of the fuel pump. The fuel gauge indicates the fuel level in the tank when the ignition switch is in the ON position. When the trip knob is pushed, the fuel gauge illumination comes ON and the fuel level registered just before the ignition switch was turned OFF is indicated, even when the ignition switch is in the OFF position.
2. All models are equipped with two fuel level sensors. These sensors are installed in the fuel tank, one on the right side and the other on the left side. Two sensors are necessary because the fuel tank is divided into main and sub tank compartments.

Scheme 8

The combination meter is provided with a self diagnosis function and a diagnostic trouble code display function which indicate DTCs for the engine, transmission and ABS/VDC control modules. To enter diagnosis mode, the diagnosis connector located near the fuse box under the right side of the driver's seat is used.

Scheme 9

PROCEDURE

1. Entering diagnosis mode

1. Connect the diagnosis connector.
2. Turn ON the ignition switch.
3. During initial operation of the meter and while the needle is moving, push the trip knob once to enter diagnostic trouble code display mode, or push the knob twice to enter self diagnosis mode.

Note. If the vehicle is driven while in diagnosis mode (vehicle speed signals input), diagnosis mode is cancelled.

1. To exit diagnosis mode

Turn OFF the ignition switch and disconnect the diagnosis connector to exit diagnosis mode.

1. Self diagnosis mode

When self diagnosis mode is activated, the system switches to warning lights, indicators, needle movement, illumination or buzzer check mode (sports shift) each time the trip knob is pushed.

1. Diagnostic trouble codes display mode

When diagnostic trouble code display mode is activated, the display switches to indicate engine control module, transmission control module, or ABS/VDC control module diagnostic trouble codes each time the trip knob is pushed. In addition to the type of control module, the display will show whether the diagnostic trouble codes are now being received, present, or not. If CAN communication is failed, "---" is displayed.

The clock unit display can be switched to indicate outside air temperature, fuel efficiency, remaining travel distance or continuous driving time, by operating a button. The DISP button is used for switching the display, and the indicated information switches in the following sequence each time the button is pressed: outside temperature --> fuel efficiency at the instant --> average fuel efficiency --> remaining travel distance --> continuous driving time These data are sent from the combination meter by means of digital communication. This clock unit is provided with a function to automatically display a failure; if the accessory power circuit is open it displays "Acc", and if the ignition power circuit is open it displays "ign". If an abnormality is detected in the communication between the combination meter and clock unit or in the received data, "Err" is displayed. If no data can be received, "Err" will always be displayed even when the indication is switched with the DISP button, but when only a specific data is not received, "Err" will be displayed only when the indication is switched to display that data. For example, if outside temperature data is not received "Err" will be displayed only when the thermometer feature is selected, and other indications such as the fuel efficiency meter will be displayed normally.

CLOCK DISPLAY

The clock shows time when the ignition switch is turned to ACC or further from OFF.

INSTANT FUEL EFFICIENCY, AVERAGE FUEL EFFICIENCY, REMAINING TRAVEL DISTANCE AND CONTINUOUS DRIVING TIME DISPLAY

The combination meter microprocessor performs calculations based on vehicle speed signals from the ABS/VDC control module, remaining fuel signals from the body integrated unit, fuel efficiency signals from the engine control module, and engine start signals, and then sends the data to the clock unit.

1. Average fuel efficiency

The value is calculated from the distance and total amount of consumed fuel since the trip meter has been reset the last time.

1. Instant fuel efficiency

The value is calculated during driving, based on the traveled distance and amount of consumed fuel recorded for a certain period.

1. Remaining travel distance

The value is calculated from the average fuel efficiency in recent 30 km (18.8 miles) and the amount of remaining fuel.

1. Continuous driving time

Indicates the total time since the engine has been started.

OUTSIDE AIR TEMPERATURE DISPLAY

The body integrated unit performs calculations based on outside air temperature signals from the ambient sensor and vehicle speed signals from the ABS/VDC control module, and then sends the data via the combination meter to the clock unit.

BRIGHT (DIMMER CANCELING) FUNCTION

The dimmer can be cancelled by pushing the BRIGHT button when the lighting switch is ON. The lights returns to the dimmed state when the button is pushed again.

PASSENGER'S SEAT AIRBAG INDICATOR

When this indicator (a mark on vehicles for Canada) is ON, the passenger's seat airbag will deploy in case of a front collision that should cause the airbag system to activate. When the indicator (a mark on vehicles for Canada) is OFF the passengers seat airbag will not deploy.
