    I started up my car this morning and, while idling in my driveway, stationary, I noticed the ScanGauge reading 9999 MPG. That didn't make much sense, so I switched that pane to display GPH, and sure enough, that was reading zero. The other three panes made sense: RPM (about 1300), LOD (about 40%), WT (about 10 C and climbing). The engine was definitely running, warming up, and using fuel, but GPH was shown as zero.

    I pulled out into the street and on heavier acceleration. the GPH reading actually moved from zero (but to a value lower than I'd expect). But as soon as I backed off on the gas (engine still running, not yet warm enough to shut off), the GPH reading was zero again.

    I unplugged the cable at the back of the ScanGauge, waited a few seconds, and plugged it back in, and it went through reconnection and then all the readings made sense again.

    Has anybody else seen anything like this?

    Interesting. You might check the release version as I know they've made changes over the years. The sad thing is you have to send it back which usually takes a week. There may be a $25 shipping charge.

    GOOD LUCK!

    I had an odd situation just the other day myself. Never saw the error again. I had @ & and other weird symbols on everything. When I got home I shut off the car and then restarted the vehicle. No issues and never seen it again. I don't worry about it any more, but it did make my heart drop that it was broke! I would miss my scan gauge or Prius for that matter!
