P0D87: Battery Charger Coupler Status Indicator Control Circuit A Low
What to do
Charging is almost certainly working — confirm through the car's app or dashboard rather than the port lights. Worth repairing, because without them every charge becomes a guess, but nothing here prevents driving or charging.
What this code means
The control circuit for one of the charge coupler's status indicators is faulty.
The coupler status indicators are the lights that tell somebody standing at the car what the charging connection is doing — connected, charging, finished, faulted — usually as colours or flash patterns around the charge port.
There are three of them, and that is the detail worth pausing on. Three separate driven circuits mean the car can show combinations rather than one state at a time, which is how a single port conveys several distinct conditions to a person who cannot see a dashboard from where they are standing.
None of this affects charging itself, and that is precisely the risk: the car may be charging perfectly while showing nothing at all. On a vehicle whose charging is silent and invisible, these lamps are the only confirmation at the moment of plugging in, and an owner who sees nothing will usually unplug and try again somewhere else. So an indicator fault reliably presents as a charging complaint, and checking the app rather than the light settles it in seconds.
The circuit is at or below its lower limit, usually a short to earth. Depending on the design this can leave the indicator permanently lit, which misleads in the other direction.

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 you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
