P2D80Charging Start Switch Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D80 is set when the start switch line is dragged below its valid voltage, typically through a short to ground or a contact that stays closed on a button that grounds the input when pressed. No manufacturer documents P2D80 publicly. In that common layout a grounded line reads as a start button held down forever. The risk differs from the stop switch: a stuck start request could begin charging against a timer setting or keep re-requesting a session, so the control unit is expected to set the code and stop acting on the input. Where low is instead the idle state, presses are simply lost. CARB demands that distinct out-of-range faults of such inputs get separate codes, hence this code beside P2D7F. The stop switch has its own low code, P2D7B.
- What you may notice
- Charging ignores the timer or starts unexpectedly before the code is set
- Start button no longer works after the fault is detected
- Likely causes
- LikelyStart switch signal wire shorted to ground
- PossibleStart switch contact stuck closed or bridged by moisture
- RareCorrosion in the connector creating a path to ground
