I am getting blind spot errors, disabled. When I connected my Forscan i found no mention of the the SODL in the DTC listing. SODR was fine? I found some wiring mess ups from when I connected the LED strip under the tailgate. I am working on those but I do not think I hit the BLIS wiring at all. I am heading in to get a new battery tonight as it looks like mine is OEM :shock Any other ideas before I break down and take it to Ford?

I thought this was in profile I will change

Without a DTC scan it is just a guess as to what is wrong. Scan for DTCs. Record them for future reference. I use Windows Active Window Screen Capture (Alt+Sys Req) to save JPGs of each DTC, then dump them into a MSWord doc. Clear the codes and run a BCM self-test checking for any returning or additional DTCs. The SOD modules are the same from left to right, so you can swap sides and see if the problem follows the module.

 

I have run for codes I would think if the actual module in the tail light was bad it would say so?

 

Found the issue. Somehow the wire for the circuit breaker/fuse was broken. Spliced and cleaned up and all is good.
