Great info on this thread.  I lost my entire trailer tire pressure program. Can't get to first base with it.  Dealer can't figure it out either.  This was after a system upgrade was installed.  Any ideas as to why I lost the whole shebang??

I just ordered the TireMinder Rhino booster for the helluvit.  It is 433 mhz, but they said it would not be compatible.  However, there is no "learning" or other pairing to do, so I am hoping it will

I called Rhino tech support and they said in the near future (?) there were thinking of making a repeater for the GM vehicles to help people that need a repeater.   Chuck

I was rooting around the GM sites and came across this interesting tid bit on the TMPS materials and some part numbers. If this helps or you do extend the TMPS unit behind the rear license plate let u

Mike I just tried to relocate my module. I made up a cable 22 gauge twisted shielded. I made up the ends and ran it under my trailer. I had the module 16 feet away from the furthest tire. I ran 22 gauge 2 pair twisted shielded about 53 feet long. I tried to relocated the module under the trailer and the truck didn't seem to recognize a receiver was present. I rang out the cable and its all good. I also put the receiver back on the truck and it recognizes it?  I ran out of time so next week I plan on taking a voltage reading as the only thing different is you had 20 gauge power wire.  I might try that also.  I'll let everyone know what's happening.

Thanks to all the contributors to this thread for a lot of great info.  What I learned is that for my 20' dual axle box trailer, I may be able to get away with just moving the receiver on the truck.  I attached a length of 1" wide steel bar to a bracket behind the license plate and moved the receiver to where you see it in the below photo.  I was able to do this using the existing service loop and connector, so no need to add an extra length of cable.  Test so far have shown that this method works great.  We'll see how well it works in the rain.  It's somewhat protected by the spare tire, so I don't anticipate any failures.  Then again, we don't get much rain here in SoCal.

I’m curious if this is still working well for you?  My rear most axle on our TT is just barely outside 23’ and it seems your solution is the easiest/best option.

 Ok a little ketchup, I ran a 18 gauge pair of red / black cable. I intercepted the 22 gauge cable about 6 inches from the ends. I also verified the cable was getting power to the end. It now powers up the TMPS and it was recognized the TMPS receiver.  I had the receiver on the ground adjacent to the wall of the trailer. I got 1 tire to see in the truck. The others I was not able to get the truck to see it. I stopped and put things away for now. I am waiting for a Deusch military bulk head connector to use in the bed of the truck next to the trailer / cam plugs. When I get that I will put it all together. I'll take the trailer for a rid to wake up all the tire sensors. Then again try to get the truck to recognize the tire sensor.

On a second note, I understand someone had a problem that the tire blew out before the TMPS monitor in the truck responded. A passerby flagged down the driver as the tire was shredded and nothing was left but rim? Any one check how long or the response time from a tire problem to the dash display?

Gecko, just read your post.  Looks like you got the power and signal end taken care of.   As for communications to each tire make sure the face of the module is facing the wheels.  From what I read this works by line of sight.  I will post some instillation pictures today of how my rig is set up.   

 

Just for notes here on the forum I made another extension cable for my truck so I don't have to keep climbing under the truck to plug in the TPMS sensor to the connector behind the license plate.   So now I have 2 jumper cables between the truck and the module which is mounted the trailer permanently   Total length around 43'.   Been working flawlessly.  

 

As for the blown tire I think the sensors transmit every 30 seconds or if it detects a significant pressure change.  Not sure what the circumstances were but if normal tire pressure is around 95 or above as the tire heats you cap off at 102.  After that you are in the dark as far as pressure goes.  At that point I monitor temperature.  Usually my tires are within 5-10 degrees of each other.  If I was to see something outside of that range I know I have a issue.  If it is not reporting the truck should pick up on that.

Here are some pics of how I set up my trailer.  I have no longer experienced any connection issues.  

#183 Module mounted center of trailer @ 15' from furthest tire angled slightly downward

#184 pic from behind last axle

#184 short extension from original module location behind license plate, this connects to extension I made for new module location on trailer.

To Sher715:  Please excuse the late reply.  I didn't get a notice about your question.  It's still working great for me.  Then again, I don't have a lot of miles on it.  I've towed the trailer twice since making the mod and it worked as designed both times.  If you're having issues, it's an easy mod and worth a try.

Thanks!  It’s going to be on my list of things to do. Need to but the sensors and have them mounted as well.

Mike,

I have been searching Amazon for the parts. Would it be possible to get the part numbers for the shielded wire? And what was the diameter of the loom you used? I love this forum. I used info to extend my trailer camera wiring and all worked well, now to this one.

Thanks.

I traded my 2020 3500 GMC for a 2021, it was no different as far as the signal went. i just went on a long trip. before i went I moved the antenna to the outside of the license plate to see if that helped. It did. I have a tri axle Toy Hauler and before moving the antenna i was constantly getting messages for loss of signal on the rear wheels & also the center axle. I now will get a message for the rear wheels abut once an hour which is much more tolerable.

Did you move the entire module or just the antenna? I thought that the module didn't really have an external antenna.

I moved what I believed to be the antenna. There are two that clip on a m0unting plate behind the license plate on one bracket. The smaller one I believe is for the keyless remote & the larger one is for the sensors. I just disconnected it from the bracket and used one of my tag bolts to connect outside the tag temporarily. There was enough slack to do so. I can take a photo latter today and post if you would like.

Yes there are 2 modules. The thin one with a clip on each end is for the keyless entry. The larger rectangular one is the TMPS trailer system. I did orient the module under my trailer so it faces the 3 axle tires, under the trailer. I am no more than 12 feet from the box to the furthest tire. I am not finished yet but maybe this weekend. I also did orient the module to face. The same way it was on the truck in case it had a internal antenna.

      2024 Silverado 2500 HD with the 6.6 Gas (L8T) Engine

      How many miles were on the truck when you bought it and was there some form of oil change history generated through a dealer or an independent shop although not much would show up if the owner had changed their own oil. Just curious if it was a maintenance issue or if there was something off from the start, surely one would think the original owner would have realized it was using a lot of oil, its hard to go back in time and find out the true story of mysteries like this. Well hopefully the warranty company will go for it and just install a new engine, that would be the ideal outcome.    I still have so few miles on my truck as per not quite 9000 and will be changing the oil shortly which has around 2700 miles on it or so and its down so little on the dipstick from where it was at the beginning of this oil change that I could make the "claim" that it uses no oil but in reality would be a very small amount, less than a 1/16 of an inch. Just driving empty/not towing and easy driving so hard to say what it would do if it had a load behind it for oil consumption. So far very impressed with the very minimal oil usage.

      Doors lock and mirrors fold in while driving

      By BIGBOYS · Posted

      I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again.  Any advice, thank you,   Ed

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

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.
