Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

You may have a couple of things going on. If the module truly isn't communicating then it has either failed or is missing power or ground. The communication code may have been set due to the module being unplugged with the key on. IN any event, you can't move the module from it's original location and if it has been removed from the vehicle it requires an alignment procedure with a special tool and scan tool.

Are you able to communicate with the module using a scan tool?

On line there are directions how to move such a unit by Ford What's the difgerence?
GMC Mechanic: sprinkles08, ASE Certified Technician replied 8 months ago

That's a completely different manufacturer and system.

Why is it necessary to mount it on the end of the frame where a grill guard is mounted?
GMC Mechanic: sprinkles08, ASE Certified Technician replied 8 months ago

Because that's where the module is designed to operate from. That's where it's field of view is designed from and it will not work if not mounted in it's original location.

When we moved it and put the grille guard on it worked perfectly well for 200 miles and then quit when another vehicle passed me
GMC Mechanic: sprinkles08, ASE Certified Technician replied 8 months ago

It didn't work perfectly, but you may not have noticed an issue immediately because it takes time for a fault code to set. It cannot be moved from it's orignal location.

I guess my alternative is to mount it in the original location and remodeling the grille guard to attach differently if that doesn't work the vehicle should be returned to the dealer and go as a lI've time customer to Ford
GMC Mechanic: sprinkles08, ASE Certified Technician replied 8 months ago

The module needs to be mounted in it's original location, it needs to be calibrated by a dealer, and nothing aftermarket can be mounted in it's field of view, if you want to retain the use of the system.
