P2D7ACharging Stop Switch Circuit High

  • Generic OBD-II code · Powertrain
How the car detects it
P2D7A means the voltage on the charging stop switch line stays above the band the control unit accepts. This refers to the signal, not to the button position: typical causes are a broken wire or switch contact on a line held up by a pull-up resistor, or a short to a supply voltage. No manufacturer documents P2D7A publicly. What the driver notices depends on the circuit layout. If high is the idle level, an open line looks like a button never pressed, so charging can only be ended by unplugging. If the switch pulls the line up when pressed, the fault mimics a held button, the case Toyota's patent calls a closed failure, and charging will not start at all. The low counterpart is P2D7B, the start switch equivalent P2D7F.
What you may notice
  • Charging does not start although the plug is connected
  • Pressing the stop button has no effect during charging
Likely causes
  • LikelyOpen circuit in the stop switch line or connector (pull-up design)
  • PossibleStop switch signal wire chafed through and touching a supply voltage
  • PossibleBurnt or broken contact inside the stop switch
