DESCRIPTION OF OPERATION
Fuel Level Sensor 46
The fuel level sensor is integrated into the fuel pump.
Fuel Gauge 47A
When the ignition switch is in the Drive position, 12 V is supplied to pin 2 of the temperature instrument from pin 22 of EDU 210. Fuel level
sensor 46 is connected to the EDU which, after processing the information, sends a 1-9 V signal to pin 1 of the tank/temperature unit.
1 V = tank empty
9 V = tank full.
Temperature gauge 47C, fuel gauge 47A, instrument lighting lamps 18, and indicator lamp 47I are connected to ground via pin 5.
Instrument Lighting 18
Backlighting of the instruments is controlled by rheostat 16 (lighting for controls) via pin 6.
Indicator Lamp 47I
The indicator lamp for the right-hand direction indicators is controlled by flasher relay 23 via pin 4.
Pilot Lamp 47B
Fuel warning lamp 47B is controlled by EDU 210. When the fuel level in the tank drops below 10I, the lamp is grounded via pin 3.
FAULT DIAGNOSIS HINTS
