This summary uses the existing diagnostic information shown in full below.
This code means that the car's battery charger isn't working properly. It's like when your phone charger isn't charging your phone right.
The vehicle's onboard computer has detected an issue with the output current from the battery charger labeled 'B'. This could mean the charger is not providing the expected current to the battery.
The P2E3C code is triggered when the powertrain control module (PCM) or battery management system (BMS) detects that the output current from the battery charger 'B' is not within the expected range. This could be due to a malfunction in the charger itself, wiring issues, or a problem with the battery.
