P0D56Proximity Detection Circuit A
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D56 is the general circuit fault of proximity detection circuit A, the line through which the vehicle notices that a charging plug sits in its inlet. Under SAE J1772 this proximity pin runs to protective earth through resistors in the plug and a switch tied to the latch button, so the car can block driving away and end charging before the plug is pulled; under IEC 62196 a resistor on the same pin also codes the cable's current rating. This is a different line from the control pilot, which carries the PWM dialogue with the charging station and has its own codes P0CF3-P0CF6. No manufacturer documents P0D56 publicly. A fault can mean no charging, or a car that thinks it is still plugged in.
- What you may notice
- Charging does not start although the cable is plugged in
- Vehicle refuses to drive or shows the cable as connected without a plug
- Charging system warning
- Likely causes
- LikelyDamaged or corroded proximity contact in the charge inlet
- PossibleOpen or chafed wire between charge inlet and evaluating module
- RareEvaluation input in the charger or control module failed
