I have a doozie!
Long time lurker...but I just had to sign up to get some help

So I am having an issue with my TPMS system. Nwe to me truck, so I don't know it's total history.

I tried to do the relearn with the truck....nothing happenes when I let the air out.

So I pull up forscan lite and read the codes.

These are the ones I get.

TPMS are B124D:02:8a and B1182:008A for the TPMS

Then when I pull up the live data for the TPMS modules, they just don't move in the picture below.

I also made sure to run 3 miles down the road at 50mph to wake up the sensors.




So at this point...should I pull the tires off to make sure I have TPMS sensors in there? Is it my module that's bad?

 

I had to replace the sensors in a 2010 about 6 months ago. One died, I assume from a dead battery. I just replaced all 4 myself. Broke the bead, yanked out the old, pulled in new valvestems and sensors, reseated the bead.

 

were you having weird issues like I am when you did it? I wonder if it's possible all mine are dead. Guy I bought it from said the fault has been on for a while

 

I replaced mine a few years ago, batteries only last so long. I know there are different frequency requirements for different years. A TPMS reset tool was required to pair them. Also read somewhere on the forum that slight voltage fluctuations can trigger a light. If I have multiple 12V devices plugged in on trips every once in a while I will get a pressure warning. Usually goes away in a few minutes and never actually had a tire going soft.

 

A couple comments....

It is not a different frequency, but sensors from 2015+ do not work in 09-14 trucks.
If 12v devices are interfering, it is more likely RF interference than voltage. It is most likely to be a problem in the 12v socket in the dash, as that is right near the tpms antenna.

 

I don't remember the exact fault, it was something like TPMS System Fault. I never pulled live data, and the truck doesn't show individual tire pressures. I just guessed that the batteries were dying, and got lucky.
I also didn't have to program anything. Just went for a drive, and the truck figured it out.

 

Around 7-8 years is typical battery life. I've seen some go 10+ years, but you are overdue if those came from the factory. I'd replace them. I paid $15-$20 each for new sensors from Amazon and have replaced them on 3 vehicles now with great success.

 

Yeah, mine were starting to get a little intermittent, especially with longer journeys around the 8 or 9 year mark.

 

that could explain it.
