I’m gonna try to make this short but packed with as much info as I can.
I bought a 2008 express van 3500 with 42k miles on it last year. The TPMS worked properly. 80 psi rear tires 40 in the front. I decided to upgrade my battery to accommodate some more electronics. At this point I haven’t wired any aftermarket stuff. Just replaced battery. Service tire system is on dash now. So I go to reprogram the tires and it flat out does not work.. I’ve been over the procedure 100 times. My vehicle does not have power windows or locks so the only option I have is to use the DIC buttons.. when I get to “press (check) to relearn” it just blinks nothing more. I have tried holding the check for 2 minutes. Nothing. Someone said make sure my door is closed. Still nothing. I will attach a video below of what it’* doing..

further more I’ve been dealing with this for over a year. There has to be a way to diagnose why it won’t relearn. I’ve found zero information on tpms problems. Only instructions on how to relearn them.

Any help leading me in the right direction would be greatly appreciated




the video quality doesn’t really show the words on the display blinking. But when I press the check button. The display blinks and that’* it
