Code??

[ForumBlue]

I got the P0683 "Glow plug control module to PCM communication circuit."
I cleared the code and restated the truck and it didnt come back on. Is this something to worry about or that needs fixed?
Thanks.

May be a one time glitch.

This code has now come up 3 times. Any idea on what I need to do to fix it? The truck starts and runs fine but every once in a while the light comes on when I cycle the key on, but still starts without hesitation.
