In this article I’ll cover the basics of getting Forscan set up, enabling keyless entry and programming the keys, enabling the AWD gauge, enabling aux input without Sync, and enabling remote start.
This is easiest to do on a Windows laptop. You’ll need a program called Forscan and some method to connect to the car. I’ve successfully used a VXDIAG VCX Nano and an OBDLink MX Bluetooth. Making these changes will require the extended licensing for Forscan, which is only available in the Windows version. You can get a 2 month free trial by registering on their forum and using this form.
Another very useful tool is the AsBuiltExplorer. It can calculate the checksum bits and performs analysis on the As-Built files for various cars. It also has a hex to bin converter.
The last two hex digits in each line are the checksum. If you’re sure you’re making all the other changes correctly, you can ignore them and click yes for the error message that will pop up when you write changes. There are a few cases where I’ll represent the checksum with “XX” because I didn’t keep track of it.
Your As-Built data may be different from mine and the other examples. The important thing to pay attention to are the bits that I’ll mark for each change. Use a hex to bin converter like the one in the AsBuiltExplorer if you need help figuring out what bits you have enabled and what to type into Forscan.
Keyless Entry
I found instructions for this here and here.
You’ll need compatible remotes. I got these keys to work with remote start as well.
To enable the factory keyless entry, you’ll need to change the appropriate bits in two different modules. After writing each change, you’ll be prompted to cycle the key off and back on.

Once these changes have been made, you’ll need to program the keys. The instructions I found are as follows:
Close the driver’s door, then using the buttons on the driver’s door lock, unlock, lock, and unlock the doors.
Cycle the ignition key off to on 8 times, ending with the key on.
The locks should now cycle. Each time this happens you have 20 seconds to complete the next action.
Press any button on the first remote, the locks will cycle to confirm.
Press any button on the second remote, the locks will cycle to confirm.
Continue with any additional remotes (up to 4 total, I believe) or turn the key off to exit programming mode. The locks will cycle again to confirm leaving programming mode.
AWD gauge
Information on this came from here.

Enable Aux Input Without Sync
I found a little information in this guide for enabling Sirius. The rest was trial and error. There is also some hardware required. An expensive cable is available from fordpimods.com. I used this cable instead, but the pins aren’t a direct fit with the connector in the Ford. I’m temporarily using some 2.54mm female crimp sockets. They’re a loose fit in the connector, but fit snugly on the actual pins. I found the pinout for the connector in this post.
FCDIM 7A5-01-01 from 0001 9000 205F to 0001 1000 20DF
Bit 16 disables aux, set to 0 to enable.

Remote Start
You’ll need compatible remotes, and you’ll either need to have factory keyless entry or follow the procedure above to activate it. I can confirm that these keys work.
You’ll also need to install a hood switch if your car doesn’t already have one. The wiring and connector will be there even if the switch isn’t.
I found a little information on enabling this feature here. The rest I figured out with the AsBuiltExplorer tool and a little trial and error.

Additional Options in IPC Module
Not all options are actually available or functional, these are just the bits to enable them under the IPC’s Settings screen. There appear to be some interactions between these values and the ones in 720-01-02. I’ll update soon with a little more info on this, and as I have time to experiment more with them.

The marked bits activate the following options:
02 Auto High Beam
03 Autolamp Delay
05 Easy Entry
06 Remote Windows
09 Auto Lock
10 Auto Unlock
13 Rain Sense Wipers
