UNIFIED CONTROL METER
●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 METER
NOTE:
Turn ignition switch to the “ON” position to operate odo/trip meter.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
●through 10A fuse [No. 28, located in the fuse block (J/B)]
●to combination meter terminal 45.
With the ignition switch in the ON or START position, power is supplied
●through 10A fuse [No. 11, located in the fuse block (J/B)]
●to combination meter terminal 46.
Ground is supplied
●through body grounds M27 and M70
●to combination meter terminal 47.
WATER TEMPERATURE GAUGE
Gasoline engine models
The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is received
engine coolant temperature signal from ECM. ECM is detected by water temperature sensor.
The water temperature gauge is received by a signal
●from ECM terminal 32
●to combination meter terminal 55.
The needle on the gauge moves from “C” to “H”
