I believe there is a fan inside of the cooled seats that sucks in air from the bottom of the seats and disperses the air out through the holes in the seat. I'm not sure if it is possible to replace parts of the existing seat to get the cooling feature, or if it is better to get a new seat. You would have to compare your edge to the same model year as an edge with cooled seats. You would have to look at the wiring diagrams for the cooled seats to figure out how to connect the seats. Then, you can use FORScan to enable the cooled seats so that they can function and you can control the cooling on the screen.

I removed the new 900mhz RTM and installed the 300mhz RTM. The DTC went away. I saved the AsBuilt data file to my computer. I installed the 900mhz RTM again and I wrote the AsBuilt file that I just saved to it. It said no data to write, but I just did the force write anyway and the DTC disappeared. I did the RTM module reboot and TPMS relearn mode. I went for a short drive and the tire pressures are working again with the 900mhz RTM. Now all I need to do is get a locksmith to program my 900mhz key.

I got my new 900mhz RTM and key fob. I remove the old 300mhz RTM and replaced it with the new 900mhz RTM. As expected, my old 300mhz key fob only works in the emergency slot, and I lost TPMS. I got a DTC: RTM U2100:00-2F Initial Configuration Not Complete. I went to the AsBuilt Configuration for the RTM and I loaded factory data from the internet. Then I did the module reset for the RTM. The DTC still remained. I did the tire pressure monitoring system train, and I was asked to retrain the front left tire. I don’t have the TPMS learning tool so I let about 6psi out of the tire instead. It didn’t seem to do anything so I just aborted the TPMS procedure. I took a drive and about a minute later my tire pressures started to pop up in the IPC because they automatically learned. I have tried to do the RTM module reset multiple times but the DTC still remains. Maybe I have to plug in my 300mhz RTM and save the AsBuilt data and write it to the new 900mhz RTM?? I only have one 300mhz key, and I haven’t programmed any 900mhz keys yet.

What do you mean by designation on the part itself? Was ML3T-15K619-JA on the sticker of the part, but ML3Z-15607-K was on the website?

I only have one key, so I will need a locksmith to program a second key. My understanding is that the RTM is not required for programming a key? If the key is programmed correctly, it should be able to start the car using the emergency slot inside of the center console? My plan is to: 1. Save the asbuilt data from my old RTM. 2. Install the new RTM. 3. I should still be able to start the car with my old 300mhz key using the emergency slot. 3. Make the new asbuilt changes to the new RTM and enable remote start. 4. Have a locksmith program the new 900mhz key. 5. Hopefully the new key should work.

I ordered a ML3Z15607G and a 5 button fob even though I don't have a power liftgate. I will find out if it works.

How did you know that the module was from a 2015 Mustang? What did you do to upgrade the firmware? Did you just need to change the asbuilt data or did you need firmware files?
