I have been working with Foxwell on getting the NT510 Elite with Toyota software to program TPMS IDs. We have gotten to the point where the tool can program 1-4. There is a 5th spot prepopulated with 00000000. Is this actually a valid sensor ID memory location? The lady helping me said it depends on whether the vehicle has a spare or not. I interpret it as whether the computer has the memory spot allocated for a 5th ID, and if it's actually monitored if programmed. I installed a larger spare tire to better match the larger 225/50R17 tires I had installed. While I had the original spare out I installed a sensor in the spare and wish to program it in. Can anyone please confirm that they successfully programmed a spare and it works just like the 4 others? I'm just not sure whether she will just say it's a limitation with the car and not the tool.... Thanks in advance!
