P0D15 code meaning
Battery Charging System A High Voltage Interlock Circuit/Open
What P0D15 means
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.

Symptoms of P0D15
- AC charging not possible
- Charge inlet light indicates a fault
Common causes of P0D15
- Most likelyHV connector in the charging path not fully seated or latched (Volvo XC40)
- PossibleBroken interlock wire or pushed-back terminal
- Less likelyMissing or loose cover on a charging component
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D15 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 15 | The exact fault in that area. |
What to do next
- Note P0D15 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 P0D15
What does P0D15 mean?
P0D15 means "Battery Charging System A High Voltage Interlock Circuit/Open". P0D15 reports an open high-voltage interlock loop in charging system A. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D15?
P0D15 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0D15 fail an emissions test?
P0D15 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 P0D15 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0D15 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
