Keyless remote and TPMS not working

Last October we received a lot of rain and water penetrated interior, pillar and sun visor. I took to the dealer and they replaced the satellite antenna.  

At the beginning of the year I would get calls from OnStar that the theft deterrent alarm was triggered. I would go outside or wherever I was and would look and the alarm was NOT going off. The dash did say theft deterrent system activated. This went on for several months and would happen like every 2 weeks. 

On April 4 on our way out of town, we stopped at a store and the suburban would not lock or unlock using remotes. I manually locked suburban and upon using the hidden key in remote to open the door, the alarm went off. After alarm cycled off, of course it would not start. I figured maybe it was a low or dead vehicle battery. I called dealer and they said it sounds like a dead battery, so I had a friend nearby come and we jump started the suburban. I drove to dealer and sure enough the battery was very low and they replaced it. After leaving I got a code on dash about  "remotes not programmed" then it went away. As we got on the interstate to leave, I lost the psi readings and it showed all lines. So I pulled off the interstate and checked the psi in all tires and they read good. The remotes still didn't lock or unlock suburban. So back to the dealer I went and they could not find the problem. It's been there for 3 weeks now and they have replaced different modules such as RCDLR, remote receiver module, BCU and other modules,  onstar antenna and cannot find or figure what the issue is.  I asked them to please call Chevy and see if an engineer can figure out problem. First they said my aftermarket window tint was not allowing remote signals in, seriously after having my suburban for 3 years now they claim its the tint?

Anyone out there encountered this issue?

They're full of crap by saying it's the tint.  Have them test the stuff with the windows down if they think it's the tint.

I'm curious if you ever figured this out. I'm having the exact same problem in my 2015 Yukon XL.

Have you found out the problem I have the same problem on my vehicle

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?

      Tire psi

      By jgaudet99 · Posted

      That's good to know, but I don't think I'll even be running them under 45 in the rear  unless it's on the sand or something but will only be for a short distance anyways!    I didn't read all the instructions in the booklet yet, but do you know let's say I set the rear psi on the placard to 45, will the warning light come on soon as it drops under 45 or is there a percentage it has to drop from the set value before the warning light is triggered?
