Communication module failure detected message

This happened at startup maybe 6-8 weeks ago. I went to the dealer and the service lady said it was from the car wash I went through with the collision sensors and nothing was to worry about. I bought it and went on. Now, over the last week while up in Bowling Green, KY it has happened many times. It seems like 60% of the time now. Has anyone else had this occur?

I plan to go to the dealer this week and demand they look into the codes, as there must be something showing somewhere.

Thanks in advance for any insight,
Mike

 

Communications module failure? Isn't that supposed to be great news?!

 

First thing that came when reading the thread title was Led Zeppelin.

Sorry couldn't resist

 

I get it. Now that you mention it, it’s in my head now. Darn it. lol

I did just add that the car wash was screwing with the collision sensors. I didn’t have that in there at first.

So…

I took it in today. Played the audio recording for the service advisor. He wanted to keep the truck for a while after looking up my records on his computer for my startups. He saw nothing for what I was hearing in their system. I really thought there would have been something. But not.

The mechanic had it running for a while and heard nothing. I then emphasized it was only at start up. They had went through more start cycles with no failures reported.

The tech was there when I picked up my truck to talk with me more. He stated that it may be where I used the power feed above the rear view mirror for my dash cam, possibly. He suggested I disconnect it for some time to see if it returns. Oddly, it has only happened once since I have been back home from Kentucky. This is a strange one to me for sure.
