P0C0D: Drive Motor A Inverter Power Supply Circuit High
What to do
As P0C0B. Ask whether the pack is also reporting high voltage; alone this points at the circuit.
What this code means
The inverter supply for drive motor A is reading high, which is usually a measurement or sense fault rather than a genuine overvoltage; a real one would be reported by the pack as well. The family's argument is at P0C0B.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
