Fuel Indicator Message
The PCM indicates which fuel system is in operation by sending a serial data message to the instrument panel. The driver information message center is contained within the instrument panel. The PCM controls the operation of the alternative fuels related messages. The messages momentarily indicate which fuel system is in operation during engine start-up. A message indicating which fuel level is being shown will also be momentarily displayed when the vehicle operator presses the fuel gage select switch.
