Low Fuel Lamp/Indicator: Description and Operation
Low Fuel Warning Lamp
The low fuel warning lamp within the instrument pack utilises an amber LED and a clear legend. The ECM illuminates the LED when the fuel gauge
pointer has reached 8 degrees from zero. The LED remains illuminated until fuel is added to move the fuel gauge pointer past 20 degrees from zero.
This provides the driver with a visible warning that the fuel level in the tank is low.
When the ignition is switched on, the ECM illuminates the LED to provide a self-check, providing there is no fault it will remain illuminated for 3
seconds or until the ignition is switched off.
The sender unit resistance thresholds for switching the lamp on and off are shown in the table below:
The power input for the LED is supplied by the instrument pack via fuse 27. The ECM provides the earth path to illuminate the warning lamp.
