P2D35Hybrid/EV Battery Inductive Charging System High Voltage Interlock Circuit Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- The inductive charger feeds its rectified DC power into the high-voltage system, so its connectors are usually part of a high voltage interlock loop (HVIL), a low-voltage circuit that breaks as soon as a plug or cover is opened. P2D35 means this loop delivers a signal, but not the one expected, for instance a level that does not track the test source being switched. A clear open is P2EB4. No manufacturer documents P2D35 publicly. GM's Volt tables show how a charging interlock is judged: the module sources 5 V into the loop and treats a reading below 30 % of that reference as a fault, Type A (P0D17 in 14OBDG01). Partly seated plugs, worn or corroded terminals and chafed wires are typical. CARB expects charging faults to be detected. Wireless charging stays blocked until the loop is sound.
- What you may notice
- Inductive charging is refused
- Fault appears after work on the underbody or after driving through deep water
- Likely causes
- LikelyInterlock or high-voltage connector at the inductive charger not fully latched
- PossibleOxidised or spread interlock terminals with high contact resistance
- PossibleChafed interlock wire near the underbody pad, which is exposed to water and stone impact
- RareFaulty interlock source or sense stage in the monitoring module
