Combination Meters
System DescriptionUNIFIED 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, A/T indicator and ICC system display segments can be checked in self-diagnosis mode.
- Meter/gauge can be checked in self-diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
- The CAN communication signals (vehicle speed signal) from VDC/TCS/ABS control unit, and the memory signals from the meter memory circuit are processed by the combination meter, and the mileage is displayed.
- Operating the odo/trip meter switch allows switching the mode in the following order.
- The odometer/trip display switching and trip display resetting can be identified by the time from pressing the odometer/trip switch to releasing it.
- When resetting with trip A displayed, only trip A display is reset (same as trip B).
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
- through 10 A fuse [No. 6, located in the fuse block (J/B) NO. 1]
- to combination meter terminal 39.
With the ignition switch in the ON or START position, power is supplied
- through 10 A fuse [No. 9, located in the fuse block (J/B) NO. 1]
- to combination meter terminals 40 and 42.
With the ignition switch in the ACC or ON position, power is supplied
- through 10 A fuse [No. 21, located in the fuse block (J/B) NO. 1]
- to combination meter terminal 28.
Ground is supplied
- to combination meter terminals 20 and 33
- through body grounds M24 and M114.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to combination meter for water temperature gauge with CAN communication line.
TACHOMETER
The tachometer indicates engine speed in revolution per minutes (rpm).
ECM provides a engine speed signal to combination meter for tachometer with CAN communication line.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable resister signal supplied
- to combination meter terminal 30 for the fuel level sensor
- from terminal 5 of the fuel level sensor unit
- through terminal 6 of the fuel level sensor unit and
- through combination meter terminal 31.
SPEEDOMETER
VDC/TCS/ABS control unit provides a vehicle speed signal to the combination meter for the speedometer with CAN communication line.
