FUNCTION

The information display can indicate the following items.

• Trip/fuel consumption readings

• Maintenance information

• Warning/Indication messages (Door open, low fuel, low washer fluid, parking brake, loose fuel cap, check

tire pressure) 

MPG

Average fuel consumption indication is calculated using vehicle speed signals from the ABS actuator and elec-

tric unit (control unit) and fuel consumption information from the ECM.

TIME/MILES

The travel time and distance since last reset is displayed.

MPG/MPH

The average speed mode can be selected to display the average fuel consumption and average speed since

last reset. The indications are calculated using vehicle speed signals from the ABS actuator and electric unit

(control unit) and fuel consumption information from the ECM.

RANGE

The range indication provides the driver with an estimation of the distance that can be driven before refueling.

The range is calculated using signals from the fuel level sensor unit (fuel remaining), ECM (fuel consumption)

and vehicle speed signals from the ABS actuator and electric unit (control unit).

DOOR OPEN WARNING

This warning appears when the ignition switch is ON and the front door LH, front door RH, rear door LH (crew

cab) or rear door RH (crew cab) is opened. The BCM receives a door switch signal from the front door switch

Unit

Description

Combination meter

Turns the oil pressure warning lamp ON/OFF according to the oil pressure switch signal received 
from BCM by means of communication. 

IPDM E/R

Reads the ON/OFF signals from the oil pressure switch and transmits the oil pressure switch signal 
to the combination meter via BCM with the CAN communication line. 

Oil pressure switch

Refer to 

MWI-40, "Description"

. 

BCM

Transmits the oil pressure switch signal received from IPDM E/R via CAN communication to the 
combination meter via CAN communication.

LH, front door switch RH, rear door switch LH (crew cab) and rear door switch RH (crew cab). The BCM sends

the door switch signal to the combination meter via CAN communication lines. Then, when the ignition switch

is turned ON, the warning message is displayed.

LOW FUEL WARNING

This warning appears when the fuel level in the fuel tank is less than approximately 11.4  (3 US gal, 2.5 Imp

gal). A variable resistor signal is supplied to the combination meter from the fuel level sensor unit to determine

the amount of fuel in the fuel tank.

LOOSE FUEL CAP WARNING

The LOOSE FUEL CAP indicator will display in the information display when the fuel-filler cap is not tightened

correctly.  The indicator 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 lines.

CHECK TIRE PRESSURE WARNING

The CHECK TIRE PRESSURE indicator will display in the information display when BCM has detected a low

tire pressure condition.

LOW WINDSHIELD WASHER FLUID WARNING

This warning appears when the windshield washer fluid level is low. When the windshield washer fluid level is

low, the washer level switch provides a ground signal to the combination meter (unified meter control unit).

Once fluid is added, the message will stay on for 30 seconds and then turn off.

PARKING BRAKE INDICATOR

When the parking brake is applied, the parking brake switch provides a ground signal to the combination

meter (unified meter control unit). Then, when the ignition switch is turned ON and vehicle speed is greater

than 7 km/h (4 MPH), the message is displayed.

Refer to Owner’s Manual for additional information display items.

DESCRIPTION

With the ignition switch in the ON position, and the mode or (N)

switch ON, the compass display will indicate the direction the vehicle

is heading.

Vehicle direction is displayed as follows:

• N: north

• E: east

• S: south

• W:  west

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.
