There's is another temperature sensor as part of the AC unit to make condensation doesn't freeze. There's another temperature sensor for the interior too.
Although the Canadian Escape for '09 had DRL enabled, the service manual didn't show it as a feature that could be enabled. I've never heard of any '09 owner having it enabled, not that there wasn't just never posted.
Why would one need DRL while in Park?

The temperature information is passed on to the display via the medium speed module communications network. Any other device on the MS-CAN network (like a reader) could also access the temperature information.
This is why it's complicated to get the temperature sensor working on a vehicle that was not configured for it originally - at least 2 devices (the EMTC/DATC module and the FDIM) must be properly programmed, and the sensor must be present and working.
As an aside, the DRL thing was just an observation - there's absolutely no reason for them to be on in park. That's just how GM vehicles used to work.

I spoke with a Ford electrical engineer when the other thread was being discussed, and he said that the EMTC and DATC modules are programmed at the factory. They can't be flashed in the field, and the programming is not related to the Smart Junction Box. He said that your best bet is to find a module from wrecked Escape with factory outside temperature.
The FDIM does not need to be programmed, since the signals controlling it are sent on the MSCAN "network".
