My brother-in-law has an 09 f350 with the trailer tow command system. How can we remove the module for a look see and maybe check out the wiring harness. He was having an issue with a message that said trailer disconnected while towing his 5th wheel. All the light worked but no brakes at the trailer. I read some place that the command module could have a loose connection. So we removed enough from the from to push my finger on the side. Now everything seems OK. I still would like to remove and have a look. Does anyone have the step by step for removal?
Does he only get the message when the trailer is connected? I know if you start to get it repeatedly even without the trailer connected its a sign your batteries are on the way out.
