Po683 not sure where to look first

Hey guys, I'm getting a code; po683 which is glow plug module communication fault . Not exactly sure what that implies.. A bad connection? A bad module? Anyone have this issue before? Know what I should Check?

Thanks everyone!

I had the same code. How is it starting?
Replaced the module and all was well again.

Re: Po683 not sure where to look first

I show the same code. Took off my tune and it goes away, either way bought a used good GPCM for like $35 shipped and it took care of it. I'm assuming you have hard cranks periodically?

I just noticed you have Vivians tune? Are you running it? The code appears with her tunes on my truck.. I am taking her tune off now for sure, to much smoke in her tunes as well

Re: Po683 not sure where to look first

Yes I am running my tune from Vivian still, and I can rule that out at not the issue.. I was getting the code before I had it tuned in the first place. It actually surprisingly, starts up pretty quick.. Occaisionally I notice it takes a little longer to fire up but it isn't that far out of the norm. I am just tired of looking at a cel .
I've been looking for a good used gpcm but everyone up here must be high.. Everyone wants north of 250 for a used one

Hmm.. I'll have to check my local dealer also just in case. And I do know the parts are usually a bit cheaper in the states than up here

Re: Po683 not sure where to look first

Truck starts runs fine but this p0683 code shows up. Was yours running or a no start situation? Is there a module? If so where is located?
