FUEL TANK LEVEL WARNING DISPLAY

Purpose

• The fuel tank level warning display notifies the driver that the remaining fuel level is low.

Function

• Fuel gauge sender unit voltage signal sent from rear body control module (RBCM)

• Fuel injection amount signal, vehicle speed signal sent from PCM

Construction

• The fuel tank level warning display is displayed in the LCD of the instrument cluster.

  

• The fuel tank level warning display and value calculation are performed by the instrument cluster microcomputer.

Operation

1. 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.

2. The fuel tank level warning display is displayed in the LCD (2) if the calculated remaining fuel amount based on each signal is approx. 10 L {2.6 US gal, 2.2 Imp gal}.

Fail-safe
