P2EB4Hybrid/EV Battery Inductive Charger High Voltage Interlock Circuit/Open
- Generic OBD-II code · Powertrain
- How the car detects it
- With inductive charging, the vehicle coil picks up high-frequency power from a ground pad and an on-board rectifier turns it into DC for the traction battery; SAE J2954 defines classes up to 11 kW around 85 kHz. Because this path carries high voltage, its plugs and covers sit in a high voltage interlock loop, a low-voltage signal wire that breaks as soon as a connector is pulled or a lid removed. P2EB4 says this loop of the inductive charger is open, and the charging path stays switched off. GM shows how a charging loop is checked on the Volt: the module feeds 5 V and compares the returned share, with a low reading set as type A. P2D35 covers implausible loop signals. No manufacturer documents P2EB4 publicly. Typical causes are an unseated connector after repair, a bent pin or a broken loop wire.
