View Full Version : scanmaster Weird Behavior

I recently ripped out the wires going into the scan plug, but managed to put it back together (temp). It seems to work fine.

But a few days ago, it started displaying weird information. It would show a very high knock sum (255) and very high o2 readings (2.78). I scanned through some other values, and the majority of the values were frozen. The few values that that seemed to be working showed very high numbers too.

It also displayed 3 CEL codes that I have never had before.

I don't plug it into the fuse box anymore, but I still need to check all wires in the plug.

Let me know if you think it could be that the Scanmaster has lost it's mind.

most likely a bad connection causing the data to be misread.
