System DescriptionNJEL0442UNIFIED CONTROL METERNJEL0442S01+Speedometer, 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
SEL394X
NOTE:
Turn ignition switch to the ªONº 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 23
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 1
Ground is supplied
+through body grounds M28 and M67
+to combination meter terminal 10

WATER TEMPERATURE GAUGENJEL0442S04The 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 thermal transmitter decreases. A variable
ground is supplied to terminal 20 of the combination meter for the water temperature gauge. The needle on
the gauge moves from ªCº to ªHº.
TACHOMETERNJEL0442S05The 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) of the ECM
+to combination meter terminal 22 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 M28 and M67
+through terminals 9 and 10 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 24 for the fuel gauge.
SPEEDOMETERNJEL0442S07The combination meter provides a voltage signal to the vehicle speed sensor for the speedometer.
The voltage is supplied
+from combination meter terminal 5 for the speedometer
+to terminal 1 of the vehicle speed sensor.
Ground is supplied
+from body grounds M28 and M67
+through terminals 10 and 11 of combination meter
+to teminal 2 of the vehicle speed sensor.
The speedometer converts the voltage into the vehicle speed displayed.
