Meter System: Component Description

COMPONENT DESCRIPTION

Unit	Description
Combination meter	Controls the following with the signals received from each unit via CAN communication and the signals from switches and sensors.
	Speedometer	Tachometer
	Engine coolant temperature gauge	Fuel gauge
	Engine oil pressure gauge	Odo/trip meter
	Voltage gauge	Indicator lamps
	Warning lamps	Warning chime
	Trip computer
IPDM E/R	IPDM E/R reads the ON/OFF signals of the oil pressure switch and transmits the oil pressure switch signal to the combination meter via BCM with CAN communication line.
Fuel level sensor unit	Refer to [FUEL LEVEL SENSOR SIGNAL CIRCUIT CHECK ].
Oil pressure switch	Refer to [OIL PRESSURE SWITCH SIGNAL CIRCUIT CHECK ].
ECM	Transmits the following signals to the combination meter with CAN communication line.
	Engine speed signal	Engine coolant temperature signal
	Fuel consumption monitor signal
ABS actuator and electric unit (control unit)	Transmits the vehicle speed signal to the combination meter with CAN communication line.
BCM	Transmits signals provided by various units to the combination meter with CAN communication line. Transmits the security signal to the combination meter.
TCM	Transmits shift position signal to the combination meter with CAN communication line.
