Selectable Tire Pressure Monitoring System (STPMS)

Nice job! It is like when you get your first pickup truck, you start finding lots of cool stuff you can do with it..
 
Ha ha, I hope not. I spent way more time/money than I should have on my 1st truck... and the 2nd, and 3rd, and so on. As the years have gone by though, I do less to them, but still can't seem to leave anything completely stock. But that 1st one? Oh man, I'd spend hours looking for things to do to/with it.
Good times. :)
 
Anyone know how to REMOVE the sgw bypass?
The instructions say to gently pull the connect while depressing the tab of the connector.

That photo doesn't make any sense. It looks like they're pressing from the female side, which is obviously plugged into the block.

Mine doesn't seem to be working now and I want to test the wires. If I plug the Vlinker into the OBDII directly, it immediately lights up. So either I've got a bad connection, or a short in one of the wires of the bypass. If I can take it out I can hit it with a multimeter to see where the problem is, but I can't get it out.
Any tips?
 
Insert a Small Tip Screwdriver as shown and press down on the Tab. Pull when holding it down. It will come out. I shaved mine down so it can be removed without this process.

That image is just the back side of the connector with no wires inserted into it.
 
Okay, that makes a little more sense. I'll see if I can figure it out with that.
Thanks guys.

Thanks for the help guys, I was able to unplug them. I was trying to find a release tap on the outside of the plug, not in a position that sort of looked like it's inside the wire holes. You guys helped me make sense of what I was looking at on the stock phots.
I decided to add a better photo (that actually have wires attached) for anyone else trying to remove the plugs.

I have one of the plug with the barb filed down. Now the plug pulls out of the socket easy enough. It's still snug in there since I didn't remove the tap all together, but there's nothing "locking" it into place. Much better for temporary installs.

Now the kicker. I tested the harness. I have good current through all the wires/plugs. Yet the VLink doesn't light up when it's plugged into the harness, but immediately lights up when plugged directly into the OBDII.
I must be missing something, so I'll have to revisit the instructions.

Why don't you just get setup with AlfaOBD or Jscan and set the threshold to whatever you want and/or turn the TPMS off (set to TPIS)?

Hello Brutal, I have a 2023 Ram 3500 and would like to reset the threshold tire pressure alert limits. I do have an AlfaOBD and the bypass cable. What exactly does need to be reset in the AlfaOBD? A certain code or what? Thanks

Assume you have already activated the TPMS. Go to adaptation and search for "tpms". Go to TPMS Settings. Set light load for front and rear to 0 and the max load to whatever you want. I set my front to 65 and my rear duals to 35. I use the door sticker values when I tow the fiver.

So, I was being stupid, everything works just fine. It helps to plug the harness into the OBDII, not just the security plugs. Wow. Sometimes I over think things and miss the obvious. Oh well, at least now it's really easy to remove from the truck when not in use.
 
Older thread, I know, but I've been searching all the threads for troubleshooting my issue and this is the closest one I've found.

I've been empty for the past few weeks so I changed my selectable tire fill system to 'honk' at 60psi rear and 75psi front (down from the 80psi rear and 80psi front that the tires were inflated with at the dealership. The honk was nice, and allowed me to deflate all tires until I heard the honk. I deflated only because the truck just rode like a tank, and the dirt-strips showed that only the center 1/3rd of the rear tires were touching the roadway. (I hope this makes sense to someone)

Yesterday I went out to inflate the tires back up to 80psi since I was helping a neighbor pick up some pigs in a gooseneck stock trailer. I turned the selectable tire fill alert system on, and went to set the pressure thresholds back up to the 80psi for hauling - except it won't let me raise the rear above 65psi. On the display, the plus symbol is there, but when you hit the plus symbol to increase the psi to what you desire, it won't go above 65psi on the screen. So, I just used the compressor and tire fill gage (by hand) to raise my rear tires to 80psi and confirmed it on the dash display (EVIC?).

Can anyone tell me why I can't change my display to show 80psi on the selectable tire fill alert system - so I'll get a honk when filling the tires back up to 80psi?

Thanks in advance for any advice you can offer.

Truck is a '24 3500 Dually Bighorn with the Uconnect5 and 8.4" screen, not the nicer Laramie and Limited screen (near speedo) but the more simple one. The thresholds are set on the 8.4" screen, but the TPMS values show in the smaller screen near speedo.
 
I'll take a look at it PRS, thanks. I'm wondering why the dealer had them at 80 and made a point to tell me that. I'm guessing the 65psi max like you pointed out is because of the heat and increasing pressure when towing/hauling down the highway?
