Adding BLIS

[Ken Speulstra]

Where did you get your SOD modules? Did they come out of an Expedition or a different Ford vehicle? Or, were they brand new? Did you initialize your SOD modules before installing them in your Expedition?

One came from a 2014 Edge and one from a 2017 Taurus. Both have the same part number as the Expedition. Not sure what you mean by initialize before installing.

Many different vehicles share the same module. But, it's likely you need to have the code for an Expedition loaded into your modules.

Have you had this done?

I haven't gotten that far yet (I have the modules and wiring but I don't have any mirrors yet). We need to get some "As-Built" code for the SODR and SODL from a Platinum or a rare Limited that has this option.

That info is easy. It can be downloaded from fords website for free.

I was also thinking I could build something to detect the lock switch and "hit the fold button". I am an Electrical Engineer by trade. Fairly easy to design. Wouldn't cost as much as the door modules either.

This really belongs in that other thread, but I've thought about this as well (I studied EE but went in a different direction after college). The trouble is when you start mapping out the conditions (truth table) for how you would want things to work. Ideally, you'd want the mirrors to fold/un-fold only when you lock/unlock the truck with the remote keyfob which also arms/disarms the alarm. There doesn't seem to be any discrete output to tap into when the alarm is armed. Same goes for the output from the keyfob. That's all handled via CAN messages over the network.

If you wired it up to the door lock switch, you might fold/un-fold the mirrors when you really don't want them to move. Even worse, the way our DDM works, the fold/un-fold input is the same input and it's a momentary connection to ground. Thus, it's up to the DDM to keep track of whether the mirrors are folded or not and which way to drive the motors. You might get into a situation where they are folded when they are supposed to be un-folded.

In addition, I still haven't figured out how the DDM knows when to stop providing power to the folding motors. The factory wiring diagram is confusing and anything but clear in this regard. Are there limit switches built into the mirrors? Is there some sort of current sensing in the module that senses when the mirrors are in the fully folded or fully deployed position (similar to the power windows) and shuts off the current flow? Or, is it a timed output? If you continue driving the mirror motors after they reach their end position, it will create premature wear on the parts.

I actually have a hard time believing that these modules are really that different from each other with the exception of connector type, module position, or radar configuration.)

I loaded the As Built data for a Platinum on each module.

Sorry, I missed your earlier post where you said you'd loaded the Platinum data values.

It's a good bet most vehicles use the same module as this would save Ford money. BUT, with that said, the firmware for each installation is probably quite different. For example, in a document I found about adding this option to a Mustang, there was a reference made to communication between the SOD Module and a "Door Control Module."

In this case, the module came from a Ford Edge which had the door module whereas the Mustang did not. The VIN info stored in the SOD module appeared to tell the module whether to drive an output pin to illuminate the alert LED in the mirror or communicate that status via the network instead.

If the VIN is stored in the SOD Module it means that module likely requires Programmable Module Installation (PMI). I don't yet have a full factory manual for 2017 so I don't know what it says about this for our trucks.

Can you completely erase all the code stored in your SOD modules? If you were to do this, then load the "As-Built" code from a Platinum, it should work -- at least in theory!

Mod done !

Fantastic!!! I have all the parts to do this, just have not had time to work on it. Do you for sure have to remove the rear bumper? Looks like that's the only way to access the modules?

Yup you must
