[TG] [TG11] Estimated fuel level and distance to empty at zero

[JeepSWAG]

My Estimated Fuel Remaining is reading and distance to empty read zero on the MFD. These worked correctly for about 11 hours.

I have a DF200 connected to a NMEA 2000 network. I also have a Raymarine es78 MFD connected to the network.

The MFD Fuel Economy continues to display functions normally.

After speaking with Raymarine (who was very helpful) I put the following list of questions together and sent them to Suzuki. Below are the questions with responses from Suzuki.that I have;

I'm using part numbers;
- 990C0-88149-350 (SMIS Engine Interface Cable)
- 990C0-88136 (Suzuki SMIS Adapter to SDS)

Q: Are either or both of these firmware update-able? (I believe the Interface Cable is) Is the latest firmware v3.5?
A: The interface is, but it is the latest. The other is just a cable, so no

Q: Are either of these a gateway?
A: No

Q: Is the data flow from the engine unidirectional?
A: No

Q: Is the Engine transmitting PNG 127497 ?
A: No, K Line

Not related to this issue, I also asked;
Q: Does the engine transmit engine temperature to the NMEA network?
A: No it needs a C10 in the system to be able to read temperature

Per Raymarine Support, I;
- Backed up my settings
- Backed up my routes and waypoints
- Did a factory reset
- Restored my settings, routes and waypoints
- I also know that I have about 70 gallons in an 88 gallon tank. In order to initialize the fuel management, I set the tank size to 70 gallons and set all tanks full. I then changed the size of the tank to 88 gallons.

I still have some follow up to do, but need to get down to the boat to do so. Will report back with more details.
