P0D15Battery Charging System A High Voltage Interlock Circuit/Open
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D15 reports an open high-voltage interlock loop in charging system A. This low-voltage loop runs through the connectors and covers of the charging path – inlet, charger and their HV leads – and breaks as soon as one of them is unplugged, so the module can keep that path de-energised. It is separate from the interlock of battery and drive, which uses P0A0A ff. Volvo stores P0D1513 in the on-board charger of the 2021–2023 XC40 Recharge when AC charging fails; bulletin TJ 36522 blames catches on the AC HV connector between inlet and charger that were not fully closed at the plant and has the connector reseated and latched. GM's Volt and ELR monitor such a charging loop with a 5 V source, and a Ford patent describes interlock shorting bars in connectors. Other loop faults are P0D16–P0D19.
