Low Fuel

The LOW FUEL message and Fuel Pump ISO are shown on the IP reconfigurable message display. A resistive type fuel sender is located in the fuel tank. The fuel sender is connected to the PCM via discrete inputs. The filtered fuel data is sent from the PCM to the IPC, via the class 2 serial data message.

The IPC uses the fuel data received from the PCM and a software program to determine the proper fuel level to display. If the fuel level is below 9.5% or E, the LOW FUEL message and Fuel Pump ISO illuminate (there is a 30 seconddelay before the light turns on). The IPC also sends a message to the BCM to chime 4 times when this condition exists.
