P2D7BCharging Stop Switch Circuit Low

  • Generic OBD-II code · Powertrain
How the car detects it
P2D7B is stored when the charging stop switch line is pulled below its permitted voltage, most often by a short to ground in the wiring, water in the switch or a contact that no longer opens on a switch that grounds the line when pressed. No manufacturer documents P2D7B publicly. Here the effect is mostly the reverse of P2D7A: on the common ground-switching layout a grounded line reads as a stop button held down. Toyota describes exactly this situation for its charging stop switch, where a permanent stop request blocks the start of charging, and adds a user procedure to override the stuck button. If instead low is the idle level, the stop request is lost. The high counterpart is P2D7A; the start switch has its own low code, P2D80.
