P2D5D: Battery Charging System Positive Contactor C Stuck Open
Standardized SAE J2012 code · P2Dxx codes
What does P2D5D mean?
The positive contactor C of the battery charging system reports a stuck open condition. HV charging path cannot be commanded reliably.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Contactor contacts oxidised
- Medium Contactor coil burned out
- Low Carbon or debris buildup preventing free movement
Likelihood is a general estimate across vehicles; your make and model may differ.
Add your car to see reports of P2D5D on the same make and model first.
