P0C00: Drive Motor A Current Low
What to do
As P0BFF. This one rarely stands alone — look at what else is stored, because low current usually means the inverter is holding back for a reason recorded in another code rather than the motor being at fault.
What this code means
Drive motor A is drawing less current than the torque being asked of it should require.
This continues P0BFF, where the family's argument lives: this is a value code, not an instrument code — the measurement is trusted and the number is wrong.
Low current for a given torque command is the direction of the motor not being driven, rather than of the motor being in trouble. The inverter may be limiting itself for a reason recorded elsewhere — temperature, a supply fault, a position-learning problem — or a phase may not be conducting. So a Low reading is usually a symptom of something else in this block, and the useful move is to read the whole code set rather than this page alone.

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.
