The low fuel warning light warns the driver that the remaining fuel level is low.
The instrument cluster calculates the fuel quantity based on the following CAN signals, and if a remaining fuel amount of approx. 10 L {2.6 US gal, 2.2 Imp gal} (fuel gauge displays remaining two segments) is detected, the low fuel warning light illuminates.
Fuel gauge sender unit voltage signal sent from rear body control module (RBCM)
Fuel injection amount signal, vehicle speed signal sent from PCM
The instrument cluster microcomputer controls the low fuel warning light illumination on/off based on the remaining fuel amount calculation that is calculated by the instrument cluster.
The low fuel warning light is set in the instrument cluster.
The Type A instrument cluster displays a warning message in the LCD simultaneously when the fuel tank level warning light illuminates. For details on the message, refer to the FUEL TANK LEVEL WARNING DISPLAY.
When the ignition is switched ON (engine off or on) the instrument cluster receives (1) the fuel gauge sender unit voltage signal from the rear body control module (RBCM), and the fuel injection amount signal from the PCM.
The instrument cluster turns the transistor on (2) if the calculated remaining fuel amount based on each signal is approx. 10 L {2.6 US gal, 2.2 Imp gal}.
When the transistor turns on, a ground circuit with the low fuel warning light is established and the low fuel warning light illuminates (3).
Function not equipped.
