Okay, I just added a TPMS to the spare and rotated it in. I bought the TPMS from a Ford Dealer, but had Discount Tire do the rotation and balance— I can’t trust the local dealership anymore…
I had the local dealership do my oil change, but the service representative objected to a tire rotation and balance. The service representative became especially annoyed when I requested a five tire rotation. I scheduled this weeks ago with them, and they also didn’t do the recall for Reprogramming Tailer Relay Module — he said 5 hours wasn’t enough time (the whole reason I came in at 7:30 am). Bottom line, it was such an issue, I honestly can’t trust the dealership at this point to actually do the work. So I bought the TPMS and went to Discount Tire. I am changing dealerships…
Discount Tire tested the Ford TPMS with a programming device and found it to be non-responsive (the device lets the technician check/read the TPMS and also is used to assign a TPMS to a tire location in the truck computer). All the other TPMS devices on the truck could be read by the programming device.
I immediately returned the TPMS to the dealership and got a replacement — the replacement was also not readable. I had Discount Tire mount the TPMS into the spare anyway with the assumption it must activate after being driven a distance. Discount Tire technicians were skeptical. I drive home and did the reprogramming myself as per the manual — it worked.
I returned to discount tire and they verified the TPMS was functioning with their programming device.
Bottomline, if you buy a TPMS from Ford it will not be activated until you’ve driven a distance with it over 20 MPH. You will then need to assign it to the tire position as per the owners manual.
