COMBINATION METER

The combination meter receives signals from switches, sensors and modules to control the following functions:

Meter system : arrangement of combination meter

Meter system : fail-safe


Meter system : fail-safe

The combination meter activates the fail-safe control if CAN communication with each unit is malfunctioning.

Speedometer

Speedometer : system description


Speedometer : system description

The ABS actuator and electric unit (control unit) receives each wheel speed sensor signal and provides a vehicle speed signal to the combination meter via CAN communication.

Tachometer

Tachometer : system description


Tachometer : system description

DESCRIPTION

The crank position sensor sends a crankshaft position signal to the ECM. The ECM provides an engine speed signal to the combination meter via CAN communication lines.

The tachometer indicates engine speed in revolutions per minute (rpm).

Engine coolant temperature gauge

Engine coolant temperature gauge : system


Engine coolant temperature gauge : system description

The engine coolant temperature sensor sends an engine coolant temperature signal to the ECM. The ECM provides an engine coolant temperature signal to the combination meter via CAN communication lines.

The engine coolant temperature gauge indicates the engine coolant temperature.

Fuel gauge

DESCRIPTION

ODO/TRIP METER

The combination meter calculates mileage, based on the following signals and displays the mileage on the information display.

SHIFT POSITION INDICATOR

Displays the position of the shift selector based on signals received from TCM via CAN communication.

OUTSIDE AIR TEMPERATURE INDICATION

Displays the ambient temperature based on signals received from:

LOOSE FUEL CAP

The LOOSE FUEL CAP message will display in the information display when the fuel-filler cap is not tightened correctly. The message will turn off as soon as the ECM detects the fuel-filler cap is properly tightened. The ECM provides a loose fuel cap signal to the combination meter via CAN communication.

LOW TIRE PRESSURE WARNING

This warning appears when the BCM detects low inflation pressure or a system malfunction. The BCM sends a signal to the combination meter via CAN communication to illuminate the low tire pressure warning lamp. In addition, a warning message will be displayed in the vehicle information display.

TRIP COMPUTER

ECO Pedal Guide

The ECO pedal guide displays accelerator pedal angle driving and the guideline of ECO
driving according to
according to information recieved from the ECM via CAN communication.

When the Eco pedal guide bar is in the green range, it indicates that the vehicle is driven within range of economy drive.

If the Eco pedal guide bar is out of green range, it indicates that the accelerator pedal is depressed over the range of economy drive.

Compass


Compass

COMPASS : System Description

DESCRIPTION

With the ignition switch in the ON position, and the mode switch ON, the compass display will indicate the direction the vehicle is heading.

Vehicle direction is displayed as follows:

ZONE VARIATION SETTING PROCEDURE


ZONE VARIATION SETTING PROCEDURE

The difference between magnetic north and geographical north can sometimes be great enough to cause false compass readings. This difference is known as variance. In order for the compass to operate properly (accurately) in a particular zone, the zone variation must be calibrated using the following procedure.

Zone Variation Chart
Zone Variation Chart

  1. Determine your location on the zone map.
  2. Turn the ignition switch to the ON position.
  3. Press and hold the mode switch untill the current zone number appears in the display.
  4. Press the mode switch repeatedly until the desired zone number appears in the display.

Once the desired zone number is displayed, stop pressing the mode switch and the display will show a compass direction after a few seconds.

NOTE:

Use zone number 5 for Hawaii.

CALIBRATION PROCEDURE

The compass display is equipped with an automatic correction function. If the compass display reads “C” or the direction is not shown correctly, perform the correction procedure below.

  1. Press and hold the mode switch untill the display reads “C”.
  2. Drive the vehicle slowly in a circle, in an open, safe place. The initial calibration is completed in about 3 turns.

NOTE:

In places where the terrestrial magnetism is extremely disturbed, the initial correction may start automatically.
