So my wife is driving to work this morning and the DIC gives this display. She shuts the car off and calls me.So I ask what is the coolant temperature is. She says 100 degrees. So I ask her to read what the gauge button is reading. she gets to coolant temperture and it reads xxx. So I check the radiator fan and its running. The coolant level is good. So off to the dealership we go.Has anyone seen this?

Bet the coolant temp sensor took a hike.

Yep, a good bet. The computer turned on the fan, and shut down the AC based on bad data.

It would be hard to explain to a wife how a hot engine sounds/looks: hissing, creaking/snapping/popping as it cools after shutdown, maybe some extraneous steam/humidity, feeling heat on your face...

check your maf sensor harness, if it is unplug or lose you will get that exact message with the fan on. good luck.

I did it when in stalling my headers

dumb question here, what's the "maf sensor harness"? I'm having the same issue with my air. On heavy acceleration the air just shuts down and comes off/on again.

I don't any message displayed but I do notice that the control panel changes (the bars to represent how hi/low the fan is running) disappears. It's kind a wacky.

Awww, come on guys, it's so simple. Maybe you need a refresher course. Hey! It's all ball bearings nowadays. Now you prepare that Fetzer valve with some 3-in-1 oil and some gauze pads. And I'm gonna need 'bout ten quarts of anti-freeze, preferably Prestone. No, no make that Quaker State

A little line I always like to quote from the movie "Fletch".

your car is supposed to do that, under wot to give you max power, the ecm will shut off ac. maf harness is the harness where you plug into the mass air meter. it is also the iat sensor in the c6.

thanks for the lessons folks!

Dealership said lose or bad connection at C 184 What the heck is that?

FYI the C6 does not have a temperature sensor. Check out this recent post.

I don't see anything in that thread about a coolant temperature sensor...but I did see a lot about how the coolant level is calculated using temperature profiles, which are obtained using an old fashioned temperature sensor.

If you want to see the coolant temperature sensor, look in the driver-side cylinder head just in front of the Number 1 cylinder exhaust port...Or, if you have the 2006 Service Manual, you can see a diagram with it on the bottom of page 6-213.

I believe "C184" is a connection or connector ID tag on one of the engine controls schematic diagrams. But...I wonder if he got the connector ID number right...C184 is in the reference voltage circuit to the fuel tank pressure sensor.

It's been awhile since I read that post. It's the low coolant sensor in the surge tank that was eliminated.

I had the exact same thing happen to my 2007 C6 today, June 16, 2018.
Temperature gauge bottomed out to nothing (100) and reading "Hot engine Air conditioning turned off" Coolant level good. Radiator fan running...no leaks.

See3See6....what did you find out from the dealership?
Was there an answer to this question that I didn't read?

Was the C 184 connection bad or was it loose?

The last post before yours was 12 years ago.

Check to see if it sucked up some leaves or grass clippings between radiator and condenser.

allprohq

Yes; Batman75; I saw that; and thought that I'd put a comment here before I made a new post.

Wonder what the outcome was since the dealership said that it was a C 184 connection that was bad/loose....then someone said that C 184 was a code relating to the fuel tanks and that must have been a false code.

I appreciate the reply, bud.

allprohq

Yeah...I thought of that and also of sucking up a plastic bag, too.
I checked them both soon afterward and found no obstruction.

One of my vette buddies told me it might be a computer "glitch" and to let it cool down and turn it on again and again to see if it would correct itself.....I did that and NO...it did not.
Same message, a little rough to start, and fan running extra hard from the get go even when the engine is cold.

Hmmmmmm?
Thanks, Vettamous......

Batman75

It's very easy to overlook that. If the OP is old like many of us, he may not remember what the outcome was.
