Safety first: This typically indicates a non-critical condition, but always verify the charger and cable are not overheating.

Check the app: Open the BYD app to see if any warnings or active schedules are displayed.
Review LED legend: Consult the BYD manual for the meaning of specific LED patterns (e.g., blue pulsing, green blinking).
Try manual override: Disable schedules and load management temporarily and start a manual charge.
Observe vehicle status: Check the vehicle’s dashboard for any charging-related messages.
If behavior is unclear: Record a video of the LED pattern and contact BYD support for interpretation.

Charger’s front LEDs blink in an unusual pattern and the unit beeps repeatedly, but no clear error code is shown.
