1 pointYou need a Windows PC and an adapter. Here are excellent instructions from the Ford Fusion forum http://www.2gfusions.net/showthread.php?tid=4573 The TC is built on the Focus platform. Module changes must be made using pre-programmed functions in Forscan. You can't change individual bits like you can on Fusion and F150s. There is a learning curve but Forscan gives you a free, powerful tool to read and change the ECU settings in your vehicle. You may be able to add options like DRL, alarm etc. Dark mode was added to the BCM programming in late 2016. You may be able to activate it with Forscan. But if your build was earlier, the dealer would have to update the programming first. I have an earlier build so I don't know if the Forscan setting for Dark Mode (I think it is called approach light) works.
1 pointHere's the instructions from my 2015 TC owners manual: Enabling or Disabling Auto lock and Auto unlock To enable or disable these features, do the following: 1. Switch the ignition on. 2. Press the power door unlock button three times. 3. Switch the ignition off. 4. Press the power door unlock button three times. 5. Switch the ignition on. The horn will chirp indicating your vehicle is in programming mode. Auto lock: Press the power door lock button for less than one second and release. The horn will chirp once if disabled or twice (one short and one long chirp) if enabled. Auto unlock: Press the power door lock button for longer than two seconds and release. The horn will chirp once if disabled or twice (one short and one long chirp) if enabled. After programming the feature, switch the ignition off. The horn will chirp once indicating programming is complete. Note: You will have 30 seconds to complete the procedure. Note: You can enable or disable the auto unlock feature independently of the auto lock feature.
