Bought a used 2010 Platinum and it had TPMS light on. Three sensors were bad and I replaced them all (with Motorcraft TPMS12's) and they all work correctly now. For some reason the TPMS module isn't receiving their signal after entering program mode by turning flashers on/off three times. It does go into learn mode and the instrument cluster says to program LF sensor. I've had lots of F150's and am familiar with how to program correctly. Even with new sensors held in my hand right next to my TPMS programming tool triggering them the horn never chirps recognizing the sensor. Suspecting something is wrong with the module itself but have no idea where it's located. Thought it was above the body module in passenger a pillar next to 4x4 control module but it's not.

There are no aftermarket devices plugged in and I tired it with the doors opened as well.

It had the usual high mounted stoplight and satellite antenna leaks and the used car dealership I bought it from had removed the seats and pulled the carpet to get the water stains out before I bought it so hoping they just left something unplugged as I already found two things (ambient light switch in center console and heated seat module in back row) so hoping that they just forgot to reattach something. They did a great job cleaning the carpets but unfortunately they didn't fix the leaks....so after the first heavy rain it was all wet again so that was the first thing I fixed.

Anyone know where they put it in 2010 Supercrew?

Thanks

 

Figured it out, using the emergency flasher button on off three times horn would chirp, it would show the command on the instrument cluster that it was in relearn mode and to scan LF tire but then it wouldn't do anything as I triggered the TPMS sensor.

Using the other method of cycling the ignition key on off 3 times stepping on brake and doing it again brought up the same display on the instrument cluster, horn would chirp, and when I triggered the sensors it actually worked.

So I guess the emergency flasher procedure in the owners manual isn't correct on my 2010.

 

In case it ever does come up, the module should be right above the glove box.

 

The Emergency Flasher Button method is ONLY for when you ROTATE TIRES with previously activated sensors. This method tells the truck where the existing sensors are currently located.
You have to use the Brake Pedal / Ignition Switch method to TEACH the truck NEW SENSORS.
