What it means
The OBC message identifies an on-board charging-system fault. The shared triangle alone does not identify the fault.
What to do
Check the charging connection and reconnect the charging equipment using the handbook’s safe connection procedure. If the fault persists, contact a BYD authorised dealer or service provider.
