Vms in foretravel errors with pids

The device installed after mfg by the factory does not read the pids correctly and the factory says that is is a cummins problem and they can not correct it.

Is there a correct pid reference for the isx 600 so that fuel etc will read and not freeze the system?

Looks like an engine bug.

We occasionally see this type of bug whenever Cummins comes out with a new generation of engine software. It sounds like you have one of the first engines of the current generation, and there is a glitch in your fuel reporting. A reflash of your engine should clear it up. If it doesn't, we do have a workaround available for your particular problem.
