Scangauge D "Hangs" on startup

Has anyone with the Scangauge D ever had problems with it hanging on startup? Mine has done this twice. The guage has numbers, but like the MPG gauge will show 9999.9, the backlighting is off, and nothing moves. If I unplug it and plug it back in, it works perfectly. It always appears to happen on start, like when I've just started the engine to build air and am walking around doing other things. I come back and it's in this state.

Sounds like a bad connection.
Sometime ago I contacted the Scan D people and told them the pins on their plugs
were under sized and caused strange things to happen as the plug made and broke
contact. I reduce the size of my 6 pin plug pins and problem solved.
Something to check out in case this is your problem.

How did you reduce the size of your plugs?

The scan D uses a sealed connector for their 6/9 pin connector and there is little you can do there however on the 6 or 9 pin you plug it into can be squeezed together so it grips the pins better.
I had some loose pins in my electronic supplies so was able to find the problem
and adjust the pins one at a time so the Scan plug pins would work.
It is almost impossible to tell if the pins in fact require some pressure to make
connection with just plugging the connectors together but with something the same
size as the pins you will see they just are way to sloppy of a connection.
Hope this helps.

Thanks Art, I think I know what you are saying now. I'll check the diagnostics plug and see if any look like they need to be tightened up. I've only had the guage a few weeks and this weekend was the first outing. Twice, always upon startup I noticed the guage with incorrect readings and the backlite out. Once unplugged and plugged back in, it comes to life and worked all the way home.

Well it takes a careful approach but can be done.
As I recall on your coach the data is via a 9 pin connector and the data
speed used is up there on that system unlike the 6 pin with much slower data speeds and about anything can cause it to do crazy things.
