P2DD3 Control Pilot Charging Switch B Stuck Off

Stuck Off: although the module orders charging switch B to close, nothing changes on the pilot; the voltage sits near 9 V, the plugged-in level, rather than dropping to about 6 V. Through this switch the station thus never sees a request for energy. A contact or relay that will not close, a broken 1.3 kΩ resistor or an error in the pilot measurement can each cause this. CARB generally treats a missing functional response to a command as an output component fault, and its plug-in section adds charger faults that stop charging. No manufacturer documents P2DD3 publicly. The opposite case is P2DD4; circuit faults are P2DCE to P2DD1; the switch A equivalent is P0CFD. At the station the car is recognised and may show as plugged in, yet no energy flows.

Likely causes

Symptoms

• Car recognised at the station but no charging
• Charging error message

Repair estimate

Typical range across vehicles; the real cost depends on what the testing finds.
