B0247Passenger Window Switch Circuit

  • Generic OBD-II code · Body
How the car detects it
B0247 is listed in none of the publicly available J2012 sources and no carmaker publishes it; passenger window circuit faults have the code B0501. The passenger switch is the simpler partner of the driver's master block: it moves only its own window, and the master can override it or lock it out. In Honda's US7145299B2 the passenger door unit keeps its own up and down buttons wired across its drive transistors, so they still work while the master line is idle; should the master command up while the local down button is pressed, a relay lifts one motor terminal off ground. A circuit code therefore points to the passenger switch, its plug in the door or the line to the master. FMVSS 118 restricts when such a window may move without the ignition key.
