As most people are aware, the main and sub fuel level is displayed as an overall sum of both by the standard vehicle cluster. The low fuel light is also triggered by the sum of both levels. The situation can hence occur that with a transfer system problem the main tank can run low while the sub-tank is not empty. It is hence possible for the engine to run dry while neither the fuel light is on nor the tank fuel gauge is showing low. The actual fill level of either tank level is available as a combination meter internal value and can be accessed by specialised scan tools.
With X-gauge codes available for the auto tranny to read sump and torque converters temperatures, that are also not standard OBD2 codes, I was hoping that the individual tank fuel level read out could also be obtained via X-gauge programming for convenient general monitoring if there are limited fuel choices and remoteness of travel warrant higher awareness levels. This would be a very easy check to detect early problems with a possibly clogged transfer filter that has no minimum flow monitoring.
Has anybody achieved this? Any ideas what one can approach this?
