Looking for a favor from anyone who lives life on the edge with no TPMS.
I’m trying to figure out if your truck will go into learn mode even if you have no sensors in your wheels.
I always bring my express van drama here. I’m fairly certain it falls in the NNBS category (2008 express NNBS style steering wheel and cluster).
I bought the van in 2019, the tpms system was working. I replaced the battery with an optima battery shortly after and the systems all reset. No readings from the TPMS system. Tried to relearn them and my van just would not go into learn mode. Searched the web with no luck. I let it go for months. In like 2020 I bought 4 new tires and I asked them if they could figure out why my sensors wouldn’t work. They called me and told me it would be like $500+ to even diagnose so I told them to just rip all the sensors out and install regular valve stems because 1 of the sensors was leaking anyway. I’ve chalked it up since then.
Fast foward to now. I’m exploring what I can do to try fix the issues. The information I’m receiving from other sites is that possibly the vehicle won’t even enter learn mode if no sensors are nearby/active. But no solid answers just speculation. I have my doubts because I have a hard time believing all 4 sensors went bad at the same time when I changed my battery in 2019.
If anyone who doesn’t have sensors installed could do me a solid and let me know if your truck will enter learn mode or just doesn’t respond when you try it. I’d greatly appreciate it.
When i did mine, i activated the tpms learn via a tech2, then i used a cheap little yellow activator wand thing on the sensors following the instructions i found talking about what wheel to start with.
The wand thingy i guess wakes the sensor up to check condititon of some basic shit, then the tahoe can read.
I get a honk, then move to the next sensor following the manual.
This is what i have for my 09.
It also worked for my wifes 2011
Edit: no judge here, hell i talk about my pos jeep project here (aka STD jeep).
And i might have mis read, going w/o tpms, or your trying to learn a new set?
