P2DBDBattery Charger B Coupler Lock Position Sensor Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P2DBD is the plausibility fault of the coupler lock feedback on charger B: the signal is electrically valid yet does not fit what the lock is doing, for example a travel that is too short after a lock command, or longer than the pin could ever move with a plug inserted. No manufacturer documents P2DBD publicly. GM's patent US8936482B2 uses that second case to spot a broken or missing pin, since the computed travel then passes the locked end stop. Mercedes lists the A-side code P0D9F00, a malfunctioning position sensor of the charging cable lock, for the 22 kW charger of the smart electric drive (LI54.10-P-067823); loose low-voltage contacts at the charger were behind it. While the lock state is doubtful, charging is usually refused. Hard low or high faults are P2DBE and P2DBF.
- What you may notice
- Charging at inlet B refused
- Plug cannot be locked or released normally
- Likely causes
- LikelyLock pin broken off or missing, so the measured travel is implausible
- PossibleLock mechanism sticking or jammed by dirt or ice
- PossibleLoose low-voltage contacts at the charger or actuator
- Repair
- Medium · Usually a job for a workshop.Typical cost: €60 – €900
