Code SCM_f027 was reported by the “Supercharger — stall module” controller in the car. The letter “f” in the middle places it among entries of the fault type.

The control module of a Supercharger stall. These codes arise on the charger side rather than in the car — typically during the vehicle isolation test before charging starts.
The more serious level. The affected component has shut down or is running in limp mode. These codes belong in a service centre.
This is how the fault is named inside the car's firmware. For codes without a description it is the most precise clue there is — the name itself says what the event is about.
The text below comes from Tesla's technical documentation. We leave it in the original English so that translation cannot shift its meaning.
Alert may be shown on the supercharger while a car is charging. This alert may indicate an insulation breakdown or other loss of isolation resistance in one of the following:The DC cabling between the supercharger and the car.The DC cabling between the charge port and high voltage junction box (HVJB), If while charging, anywhere inside the vehicle's high voltage DC system.
This part is written by you. If you have had code SCM_f027, tell us when it appeared, what brought it on and how it ended — for the next person, one such sentence is often worth more than the entire service documentation.
Be the first. A nickname and a few sentences are enough — they will make this page useful to the next person standing by their car with the same message.
No e-mail, no registration — a nickname and your text are enough. The comment appears straight away.
Comments are written by visitors to this site. They are not advice from Tesla or from TesList and we do not verify them — treat them as one person's experience with one particular car.
Copy it exactly, letter and number included. Photographing the screen is safest — codes often differ by a single digit, and mixing them up leads somewhere else entirely.
Some codes clear after a screen restart or after the car sits locked for a few hours. If the code does not come back, it was usually a one-off glitch.
A one-off entry and a code that appears after every drive are two different things. It helps a service centre enormously if you know exactly when it shows up.
With airbags, brakes, steering and high voltage there is no point waiting it out. With the other groups you can watch and see whether the code returns at all.
Error codes are only part of the picture. For cars on TesList you also see battery health pulled straight from the vehicle, plus a price calculator that works out from current listings what a given car is actually worth today.
