“HARNESS LAYOUT” (EL-550).
System DescriptionNJEL0442UNIFIED CONTROL METERNJEL0442S01Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit built-in combination meter.
Digital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
Odo/trip meter segment can be checked in diagnosis mode.
Meter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METERNJEL0442S02
SEL175W
NOTE:
Turn ignition switch to the “ON” position to operate odo/trip meter.
POWER SUPPLY AND GROUND CIRCUITNJEL0442S03Power is supplied at all times
through 10A fuse [No. 12, located in the fuse block (J/B)]
to combination meter terminal 29
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 30, located in the fuse block (J/B)]
to combination meter terminal 30
Ground is supplied
through body grounds F118 (QG engine models), M28 and M67
to combination meter terminal 32

WATER TEMPERATURE GAUGE (QG AND YD ENGINE MODELS WITH COMMON RAIL)NJEL0442S09The water temperature gauge indicates the engine coolant temperature.
ECM provides a engine coolant temperature signal to combination meter forwater temperature gauge with
CAN communication line.
WATER TEMPERATURE GAUGE (YD ENGINE MODELS WITHOUT COMMON RAIL)NJEL0442S04The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is based
on the resistance of the thermal transmitter.
As the temperature of the coolant increases, the resistance of the thermaltransmitter decreases. A variable
ground is supplied to terminal 35 of the combination meter for the water temperature gauge. The needle on
the gauge moves from “C” to “H”.
TACHOMETER (QG AND YD ENGINE MODELS WITH COMMON RAIL)NJEL0442S10The tachometer indicates engine speed in revolution per minutes (rpm). ECM provides an engine speed sig-
nal to combination meter for tachometer with CAN communication line.
TACHOMETER (YD ENGINE MODELS WITHOUT COMMON RAIL)NJEL0442S05The tachometer indicates engine speed in revolutions per minute (rpm).
The tachometer is regulated by a signal
from terminal 32 (Gasoline engine models) or 439 (Diesel engine models) ofthe ECM
to combination meter terminal 53 for the tachometer.
FUEL GAUGENJEL0442S06The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
from body grounds F118 (QG engine models), M28 and M67
through terminals 33 and 32 of combination meter,
through terminal 1 of the fuel level sensor unit and
through terminal 4 of the fuel level sensor unit
to combination meter terminal 34 for the fuel gauge.
SPEEDOMETER (MODELS WITH ABS)NJEL0442S11The combination meter receives a signal from the ABS actuator and electricunit. The speedometer converts
the signal into the vehicle speed displayed.
SPEEDOMETER (MODELS WITHOUT ABS)NJEL0442S07The combination meter provides a voltage signal to the vehicle speed sensor for the speedometer.
The voltage is supplied
from combination meter terminal 13 for the speedometer
to terminal 1 of the vehicle speed sensor.
Ground is supplied
from body grounds F118 (QG engine models), M28 and M67
through terminals 32 and 14 of combination meter
to teminal 2 of the vehicle speed sensor.
The speedometer converts the voltage into the vehicle speed displayed.
