I’m not sure if this has something to do with a problem with my truck’s head unit wiring harness or just my head unit. I have an 02 Ranger FX4 that I have had several different stereos in. I just recently installed a double-din Kenwood touch-screen head unit in my truck about a month ago. Had no issues installing. Today I get a “Miswiring DC Offset Error” message on the screen and the stereo wouldn’t even let me use the touch screen. I googled some answers and checked my wiring harness for any exposed wires-found none, checked all 4 speakers to see if they were blown-all were good, and replaced the h/u wiring harness. None of them solved the issue. Luckily I had a warranty on the stereo so I got it replaced but still came up with the same issue which makes me believe something with the wiring in the truck is wrong. I checked all connections and checked for any exposed wires probably 15 times. I’m stumped. Anybody else had this issue? Is there a certain point in the wiring harness that may chafe or become exposed over time and cause a speaker wire to short out? I’m not big into wiring so anything will help.
