P2D7CCharging Stop Switch Circuit Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D7C covers a stop switch signal that is electrically valid but does not make sense. A typical rationality test asks whether the reported state fits the situation, for instance a stop request that never ends although no one can hold a button that long, or a switch that reports pressed before any charging session has begun. No manufacturer documents P2D7C publicly. CARB requires such rationality checks for inputs where feasible and wants them stored under a code separate from circuit faults, which is the role of this code next to P2D7A and P2D7B. Toyota's patent illustrates the stuck-button problem behind it. A sticking key, a mechanically jammed trim panel or a switch with internal leakage are the usual suspects; charging may be blocked or the button ignored.
- What you may notice
- Charging blocked although the plug is seated correctly
- Stop button feels stiff or does not spring back
- Likely causes
- LikelyStop button mechanically sticking in the pressed position
- PossibleInternal leakage in the switch giving an in-between signal
- RareTrim panel or object pressing on the button
