NHTSA Complaint #11270563 — 2009 JEEP WRANGLER

HAD AN INTERMITTENT PROBLEM WITH THE AIR BAG DASHBOARD LIGHT ACTIVATING. THIS WOULD OCCUR AT SPEEDS OF ZERO UP TO HIGHWAY AND WOULD COME AND GO WITHOUT WARNING. THE OBD-II CODE WAS B1B8F, DRIVER SEAT TRACK POSITION SENSOR CIRCUIT OPEN. AFTER REMOVING THE DRIVER SEAT TO ACCESS THE WIRING HARNESS DISCOVERED THAT ONE WIRE WAS BROKEN AT THE SENSOR, PARTIALLY HELD TOGETHER BY A "THREAD" OF THE WIRE INSULATION WITH BARE METAL EXPOSED. THE WIRING HARNESS HAD BEEN INSTALLED UNDER THE SEAT WITH THE WIRE PULLED TIGHT TO THE UNDER SEAT "SPRING" WIRE SUPPORT AND HELD IN PLACE WITH A ZIP TIE. I CONSIDER IT LIKELY THAT THE UP-AND-DOWN MOTION OF THE SEAT OVER A PERIOD OF YEARS CAUSED THE HARNESS WIRE TO BREAK. THE FIRST PICTURE SHOWS THE CONNECTOR TO WHICH THE BROKEN WIRE WAS ATTACHED. UNFORTUNATELY THE BROKE WIRE IS IN THE BACK, THE ONE WITH THE PURPLE STRIPE. THE SECOND PICTURE SHOWS THE BROKEN WIRE AFTER THE WIRE PLUG WAS PULLED OUT OF THE CONNECTOR,
