FUEL LEVEL VERY LOW Message Or CHECK FUEL GAUGE Message

  1. Fuel level signal is measured only in whole gallons (or liters), no tenths, so fuel level displayed is rounded off to nearest whole number. When IPC reads fuel level as 1.0 gallon, the "E" will flash and the message FUEL LEVEL VERY LOW will display on DIC.
  2. If display is operating in DISPLAY OFF mode and fuel level falls to less than 4 gallons, all displays will illuminate and become active again. DIC will then display CHECK FUEL GAUGE.
  3. If these conditions were met and these messages did not appear, check for ignition voltage at IPC connector terminal C13 using DVOM. See Figure . If voltage is good, check fuel gauge and sending unit. See IPC MALFUNCTION SYMPTOMS  under SELF-DIAGNOSTICS and FUEL GAUGE INOPERATIVE/INACCURATE under IPC TESTS  under COMPONENT TESTING.
