Mystery PIDs
Posted: Tue May 24, 2016 7:22 am
The datalogger seems to generally be working as expected (plugged into the emulator), but I'm a little surprised that PID_DISTANCE is always showing 0, even when I turn speed up. There is no DISTANCE knob for that on the emulator app, so is this somehow running off the GPS via a passthrough from the datalogger? Or does it just not work?
Looking at the PID number, that corresponds to "Distance traveled since codes cleared" in the standard. It looks to me in the emulator app like DTC #3 is permanently set and can't be cleared, and 07 and -A flash "Set Mode 07 DTC is only supporte..." -- no way to see the rest of the error message or to get the distance to start counting. I would expect that value to be counting up anyway -- but the behavior with one DTC bit permanently set seem like it might be undefined.
