System Description/HatchbackNJEL0442UNIFIED 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.

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 32 (*1) or 20 (*2) 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 30 (*1) or 22 (*2) 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 26 and 27 (*1) or 9 and 10 (*2) 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 31 (*1) or 24 (*2) 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 29 (*1) or 5 (*2) for the speedometer
+to terminal 1 of the vehicle speed sensor.
Ground is supplied
+from body grounds M28 and M67
+through terminals 25 and 27 (*1) or 10 and 11 (*2) of combination meter
+to teminal 2 of the vehicle speed sensor.
The speedometer converts the voltage into the vehicle speed displayed.
