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.
