The Qualcomm on my freightliner went out today.Can not send or receive info. Are there any tricks to rebooting without visiting tech at authorized location? Dispatch said to try disconnecting from power source and then reconnecting after a few minutes. Would removing battery cable at post be way to test QC ?

 

Yes you can do that, there also should be a fuse somewhere.

 

an open fuse would shut it down altogether, wouldn't it?

 

Yes, like most accessories it will have "constant power" that's fused and keyed power that isn't.

Since nothing works, I'm betting the powered line is not working.

If it was, they could still beep you.

 

You should stop throwing that thing when your dispatcher pisses you off!!! :P :P :lol: :lol:

 

Try looking for a really small hole any where on the unit. On the top, sides and bottom. They usually have a reset button that you can stick a paper clip into and it reboots the unit. If you look on the front of any CD or DVD drive there is a hole for forcing the CD to eject. It's the same size.

 

Thanks all for the feedback on the inoperative QC unit.


I tried removing the cord and then reinserting a couple of times, got on the cell with the shop and was told the best thing to do would be bring it by an authorized QC tech for a look see-The last time I had had QC failure it had been in an 03 truck and the key pad was connected to a black box under the bunk ,with a line running to the dome.

In the 05 the Dome above the cab houses all the sensitive modules,chip boards, wiring relays, whatever.

To make a short story long, I ran the unit over to the QC tech who first cheked to see if the key pad was to blame by giving me a replacement.

That did 'nt work so the fix was in, ` your dome has been compromised'
said the QC tech .An hour later they'd replaced the dome.

Whether teenaged alien hackers are to blame for the incident remains to be revealed. If so , I'm sure their parents would not approve.

The last time I had a QC unit go out on me the problem was in the dome. Basically what happened is the unit became overly sensitive to weather.

The thing would only work if it was dry out and the temp was between 40 and 65 degrees out.

What is really pathetic is that based on the fact that it would start working when it cooled off at night in warm climates, or warm up during the day in cooler ones plus would not work if it was raining or snowing had me believing it was the dome from the get go and I told the techs that.

Instead they replaced the cables first, then they replaced the keyboard, then the main box under the bunk. Finally they replaced the dome, and boom. All was well in QC land.

Of course this took several trips into the shop to get it all done since while it was in the thing would work again after something was replaced and it was often late in the day before I would get the truck back. Then the next day when I was a few hundred miles down the road it would go out again. All in all I think I spent 2 1/2 weeks with a QC that only worked when it wanted to.
