Too Afraid to Ask

Trouble codes are like the car’s error messages. They help you figure out what system is having the problem instead of guessing.

Technical Definition

Trouble codes are stored diagnostic fault identifiers that point to which system detected a problem. In EVs, reading trouble codes helps narrow down whether the charging failure is related to the charge port, onboard charging components, wiring, or other modules.
