OK, I've solved my Vehicle Speed Sensor (VSS) problem and now I have good speed information coming in to my ECM. This means that the ECM should also know distance traveled, as it is merely a certain number of pulses per mile on the VSS.
My problem now is that the "trip" information in the ECM is not incrementing. Specifically, it shows 0 total engine miles, 0 total engine hours, and 0 total engine gallons. On a trip-by-trip basis, the gallons and hours increment for the current trip, but the miles don't, and everything resets to zero after a key-off/key-on sequence.
Is there a setting in the ECM that controls this? I can't find anything else to enable in the settings. I have no trouble codes, and everything else is working normally. These numbers were not incrementing with my old ECM, either, but I had the VSS disabled so I thought that was normal. I now have a new ECM and a working VSS.
Any and all suggestions appreciated.

"Any and all suggestions appreciated."
Go back to a mechanical engine! LOL

Has it been turned off with your prolink . I know the stopage codes can be deleted so its possible that this feature is not enabled

Sean - It appears that your digital gauge is only getting power with your ignition ON - this first came to my attention when I had an alternator go out on a Digital Gauge equiped car at an auction - Had to charge the battery to get it to be serviced - never noticed that the odometer was resetting till I returned it to the Auction - they pulled me in for Odometer tampering - the mileage was almost the same as when I had dropped it off two weeks earlier even though they knew I had removed and returned it - long and short of it is that I contacted Ford Engineering in Dearborn (the Auction wanted to call the FHP) they explained that when there is no power or insufficient power (the car was running on the battery till it died) after Shut down the memory sedction of the ECM could not update the parameters and they would fall back to their default which was the last time there was power after shutdown - Not saying this is the answer, but your problem sounds almost exactly the same - HTH |

Niles,
It's not the "gauge" (VMS box), it's the ECM that's screwing up. As verified with a Pro-Link.
I will double-check my ECM connections, but the ECM is supposed to keep a running total, even if it is disconnected/reconnected or even removed.
Also, the mileage is simply not incrementing while driving -- it remains at zero. And the engine wouldn't run at all with no power to the ECM.
