When you get a low tire pressure warning on the DIC, does something show up on the HUD also, like the "check guages" message?

I noticed Sunday when I went for a drive that my tire pressures were a hair lower than 30 cold on the DIC. So, before I drove it the next time I got out the gauge to get check and adjust the pressures. The first tire I checked, the RR, showed 19 psi! Checked the DIC, and sure enuff, had a low pressure warning. Didn't notice anything on the DIC or HUD when I drove it last Sunday. All the other tires checked out fine with the gauge.

Brought the low one up to 30, then checked it the following night, and it was low again. Took the wheel off and found a small screw in the tread. Either I missed the warning message, which I can't believe I would have, especially if it was on the HUD also, or the tire leaked down after I parked it.

 

I've had a few on the DIC - never showed on HUD

 

Mine does.

 

Thanks. I didn't think to look at the HUD when I discovered the tire was low with the gauge, and checked the DIC.

Am I good or what? If you have to get a flat, I guess there's no better place than in your garage, ha, ha.

 

Any DIC warning brings up the check gages caption.

 

Not sure i read this right....think it does show up on DIC as check gages, but does it shows up on HUD...those are two different things. And then to run the tire check on the gages is when you find the pressure reading.

 

What I was saying is it shows up on the DIC as "low pressure right rear tire" or something like that, don't remember the exact wording. I was wondering if something also came up on the HUD when you had low pressure, in case you didn't notice it on the DIC.

I know some things trigger a "check gauges" message that pops up on the HUD and I wondered if the low tire pressure did as well.

I keep my DIC set so the tire pressure is on display all the time, and scroll from front to rear periodically. When I discovered the tire pressure was low when I manually checked it with a pressure gauge at the tire, I turned the car on to see why I hadn't gotten a warning on the DIC. When I did, it was showing the "low pressure warning" and when I tried to scroll thru the DIC displays to see what the actual pressure was, it wouldn't scroll, but just stayed on the low pressure warning. So, I think if the pressure goes down in a tire, the DIC warning comes on whether you have the DIC on or off, and regardless of what the display is set on.

The reason I was asking is I was trying to figure out if I missed the warning while driving, or if the tire leaked down after I parked it. I thought I might have overlooked one warning on the DIC, but it would be less probable that I could have missed it if it occurred in two places, the DIC and the HUD.

 

 

I just got my '02 vert. My '88 coupe does not have the tire sensors so I have not been used to watching tire pressure. The other day I tried to get the tire pressure to 30 as shown on the door label but ended up with them inflated to 36. I let some air out not knowing how much the pressure changes between hot and cold.

The next morning was very cool and I had the low pressure warning in teh DIC and the HUD has the 'Check Gauges' message displayed. So the HUD does indicate that you need to check your gauges.

I find it interesting how much the pressure changes from cold to hot. Mine seem to vary as much as 5 pounds.

 

"When I did, it was showing the "low pressure warning" and when I tried to scroll thru the DIC displays to see what the actual pressure was, it wouldn't scroll, but just stayed on the low pressure warning.

You have to press reset to clear the message, then you can scroll through the gages to display tire pressures on the dic. I think anytime a message is display on the dic, Check gages will appear on the HUD.

 

Yes, you will get a message on the HUD saying check gauges.

 

The reason I got out the tire gauge in the first place is I had noticed the DIC was showing 28-29 cold, and I wanted them at 30. When I checked with the tire gauge, all of them were at 30 however, except the leaky one of course.

What is more accurate, the tire gauge or the DIC? I would think the tire guage. It's a good dial type gauge.

Mine get as much as 6 psi higher per the DIC on hot summer days.

 

Try another gauge and see what the pressure reads. Tire pressure will rise when hot.

 

BTW - the same check gauges message comes up if the tire is OVERINFLATED. As in 3rd run on an autocross, showed high pressures on the front tires 38+. Don't remember exactly what it said but I found it interesting that the DIC/tire pressure sensors would also warn of high pressures.
