I bought it used and when I test drove it the built in backup camera worked just fine. When I got the van it was not activating when I backed up. I took it to a Ford dealership to see if they could fix it or at least figure out what is wrong. From what they told me the onboard computer doesn’t know that there’s a built in backup camera so there was no way for them to troubleshoot it. I looked at the fuses underneath the dash and the fuse is in place and doesn’t appear to be damaged. Does anyone have any ideas on how to fix this or at least troubleshoot it?
