2025 ATTO 2 Door Open Warning: separate DOW alerts from door-lock faults

A message appears while opening a parked car’s door, but the work order says only “door lock problem”. On the Australian MY25 ATTO 2, describe Door Open Warning separately from door-lock movement so the repairer knows whether the issue concerns a warning, opening the door or something else.

DOW is a listed manufacturer function

Both Dynamic and Premium list Door Open Warning（DOW）, with blind-spot monitoring and other driver-assistance functions listed separately.[Manufacturer table][Q10] This confirms the warning feature, but several function names do not establish an equal number of independent sensors.

DOW should not be interpreted directly as an electronic child lock, or assumed to control lock opening and closing. Retain the distinctions between function names in the enquiry.

Record the original message before interpreting it

Useful records identify the exact text or icon, the side involved, the operating stage and the door’s actual movement. Save the original warning so that the owner, intake staff and purchasing do not each rename it.

These records support later inspection only. Without the applicable operating-condition text, one warning cannot establish normal function or sensor damage. Do not recreate a scenario yourself to test it.

Function count is not parts count

The product table does not establish whether lock, control and warning functions share hardware or whether the associated items are supplied separately. Wait for the repairer to locate a specific item, then check the catalogue. DOW is not automatically a standalone “door-opening radar”.

Scope and verification

This article covers only Australia, MY25 BYD ATTO 2, Dynamic and Premium.[Scope reference][Q10] The cited product specifications identify functions and parts; they are not fault or replacement criteria.

No public data was available in the reviewed material for DOW activation conditions, shared sensor relationships, positions, warnings or door-lock interaction; repair parameters, fault/replacement criteria, OE numbers, separate parts availability or interchangeability. [To be verified] Check compatibility or interchangeability using the VIN and the local Australian manufacturer parts catalogue.
