"no Bus" code
 

I just recently put on an edge box on my 99 cummins. Ran great for a few days. Well today I ran into the store and came right back out and went to start it up and my airdog wouldnt kick on, and it said "No Bus" on the odometer... any ideas to help me start looking??

What kind of Edge? Comp/Juice/EZ? Try disconnecting the 3 wire weatherpack connector under the hood that the Edge plugs into. That is a CAN Bus connector.

It is a juice.

OK, I still think you should try unplugging the Juice 3 wire connector under the hood for the CAN Bus.

are you talking about the harness for the edge? or something else?

The Edge harness. 3 pin connector all in a row. Connector is behind the fuel filter.

will that mean my edge box is bad?

There is that possibility. Unplugging it will determine if it is the Edge, or in your truck.

earlier today I unplugged it and my pump would work. But then just a little while ago I unplugged it and pump still didnt work..

When won't the pump run? Just with the key on? It will only run for a second when the key is turned on, then won't run again until you crank. If you bump the starter but not start the engine, it will run for about 20 seconds.

When the pump dont turn it wont at all. with bumping key on off, nothin works. But when it does start its fine runs great.. I am so confused on this situation. Making me want to just find a junk yard

Have you pulled codes out of it at all, with a reader?

I just took it to town. It wouldnt start when I got outside.. I unplugged edge still wouldnt start. So i tapped the airdog relay on the fender and then I dont know if that fixed it or it was a coincidence but my pump kicked on

No, I havent pulled codes out of it yet. Going to my buddies shop tomorrow and use his scan tool

Very well could be the relay, or the connections to it.

I so hope that is all it is.

Relays are definitely NOT a non failing component. I hope it is a relay as well, or even a loose connection.

would that make that "no bus" code come up though?? if my pump is not kicking on because of a relay issue???

That sure doesn't make sense to me.:humm:

I had to pull a buddy out of driveway. So just went out there to start it up. pump wouldnt power. so tapped relay for the pump, still nothing. Then i unhooked edge still nothing.. so i let it sit there for a second plugged the edge back in an it kicked on.. I think its just kicking back on when it wants to. Just makes it look like tappin relay and unhooking box fixes it but really its not. Guess ill just have to stop worry about it tonight get some sleep an think about it in morning after i put scanner on it.
