This is a real mystery. I took my car (2016 Hyundai Santa Fe 2.0T) in for an inspection sticker renewal and it failed. The rear brake lights
were flashing every time the mechanic activated my left or right signal indicator. It looked like hazard lights
were activated. Lots of flashing lights
. Obviously, not a normal situation.
I have a Scamp
13" with standard factory brake lights. I also have trailers brakes
. Everything has been functioning normally for five years (I think). Suddenly, a royal light
show! Evidently, the Hyundai has a four tail light
system and the Scamp
has a two tail light
system? At least, that is the way I understood it from my mechanic.
I had a fully functioning after-market wiring harness to a seven way plug. Now I have no trailer wiring harness at all - but I have my state inspection sticker.
Where do I go from here? Do I need the $160 Hyundai wiring harness? Is there anything "special" about the Hyundai facotroy part? Or do I have a problem with one of the computer modules, instead?
Is it a fault in the trailer brake wiring? Or do I stand at the mercy of unscrupulous Hyundai dealerships to muck up a simple repair or fix? I can't tow or camp until this is resolved.
Any and all opinions welcome.
