P2D35 code meaning
Hybrid/EV Battery Inductive Charging System High Voltage Interlock Circuit Performance
What P2D35 means
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.
P2D35 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2D35
- Inductive charging is refused
- Fault appears after work on the underbody or after driving through deep water
Common causes of P2D35
- Most 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
- Less likelyFaulty interlock source or sense stage in the monitoring module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2D35 means

| 2 | Generic code (second SAE range): it means the same on every make. |
| 35 | The exact fault in that area. |
What to do next
- Note P2D35 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2D35
What does P2D35 mean?
P2D35 means "Hybrid/EV Battery Inductive Charging System High Voltage Interlock Circuit Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2D35?
P2D35 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2D35 fail an emissions test?
P2D35 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2D35 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2D35 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
