"Check Brake System" Message
On a cold start I get a flash on message screen "Check Brake System". It only appears for a split second and then its gone and doesn't come back till the next cold start. 2017 6.7 Lariat with adaptive cruise.
I would appreciate any help with this one.
Thanks.

first thing I would do is to check the batteries, First is the eye on them green? Then load test each independently.
That is where I would start, due to the age of the batteries and the time of year it is.
Others will respond with their thoughts.

don't just buy the batteries, have them load tested and have codes read first.
I would not say that is your issue, but I would think to start there.

My truck is only a year old with 15K miles and dealer replaced batteries once at 4K miles due to them leaking. About a month ago at start up I got all kinds of wrenches, odd lights and warnings. I went replaced the batteries with Norstar replacements. Yep 700.00 a pair, but guess what, no more leaks, no more warning lights, etc. Factory ones were both in the green but I wouldn't even mess with the stock ones.

many have had the issue including me. Replacing the batteries resolved it. Use a battery tester to check your batts, one of mine had a bad cell.

I had already purchased the batteries before I read the further suggestions. I went with Interstates from Costco. It was beginning to turn over slowly and now it spins well. Looks like it solved the message issue, I will know for sure in the morning.
Thanks

Same here.
Sounds like me exactly. 2017 6.7 with 60K miles - had to jump it twice in the last 3 weeks on cool mornings. Was getting the "Hill Assist" and "Traction Control" warnings also, but hit the grey connector next to the spare with dielectric grease got rid of those two errors. Went with the Costco Interstates for $99.99. That fixed the momentary "Check Brake System" alert. I wanted to at least consider the Interstate AGMs for $164.99, but the tire guy at Costco said his Interstate rep told him they will not have them for several months "due to COVID." That simplified the choice and saved me $130.
