Smart Data Link Module Adapter - What is it?

[Carl_Sj]

I'm installing my Ford trailer brake controller and while under the dash I found the Smart Data Link Module (SDLM) (it incorporates the OBD port) just hanging under the dash with the adapter in the photo hooked up to it. It plugs into the SDLM and has an OBD connector that is attached where the SDLM would normally mount. It looks like a poorly installed aftermarket add-on. The adapter connector mount doesn't have the same bolt spacing as the original, so it was only held on with one screw. The adapter has an extra connector (or two?) coming out of it, that was just twist-tied in place. I took the adapter out and put the SDLM back in place (the adapter can still be connected if needed).

What the heck is this thing?

Did you buy your Ranger new or used? Looks like some kind of "T" adapter, maybe for some add-on gauges or tuner of some kind. I'd leave it off for now. Maybe someone else has more knowledge?

The truck is new.

Maybe a programmer cable? Might belong to the service department of your dealer?

That looks like a dongle for an add on device that would use the ODBII port and still be able to plug in a diagnostic tool. I think I saw where the Ford dashcam plugs into the OBDII port.

Hi Carl,

The dealer owes you and explanation on this as this is not OEM. Something smells here. Our local dealer installs an "alarm system" that they charge a million bucks for nothing more than a system that can shut the Truck/Car off if you miss a payment.... At least this has a bridge connector so no wire damage was endured, but of what is this jumper harness an aftermarket system.

I sent them a request for more information. I'll let you know if/when I hear back.

The dealer responded with this reply, "...what you are seeing is most likely our GPS system. You may have purchased it [I didn't] or it may have been left in there accidentally."

Interesting that they never mentioned a GPS system when we purchased the truck.

Is there a Ford part number molded into it? Might be worth a Google.

 

[Carl_Sj]

Like Phil said, it's not a Ford part. There's no part number (from any manufacturer) on it.

I read this thread with great interest. Any further word from the dealer?

Like the other comments, I too feel like this is super sketchy.

Dealers seem to have a habit of replying or answering questions only when they want. Especially after the sale.

The entire can bus is not available from the front connector. Can only access some modules. The smart datalink is essentially a gateway for other modules. Splitter cable to access rest of modules on buses not on main plug.

Some engineer (most likely) or line worker left it there by mistake.
