Low Fuel

The PCM receives fuel level information from the fuel sensor. The IPC receives a class 2 message from the PCM indicating the fuel level information. 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 second delay before the light turns on) in the message center. The IPC also sends a message to the BCM to chime the audible warning 4 times when this condition exists.
