2025 DOLPHIN Premium cabin alerts: CPD is not driver fatigue monitoring
Australian MY25 DOLPHIN Premium lists CPD and indirect DFM separately. Keep the original alert identity rather than guessing a camera or sensor.
After a cabin-related alert, an owner may remember only “the monitoring in the car” and request a camera. Distinguishing CPD from DFM on Australian MY25 DOLPHIN Premium helps the repair record retain the original function identity.
The factory lists two separate names
The technical table lists Child Presence Detection (CPD) and Indirect Driver Fatigue Monitoring (DFM) as separate functions.[Factory equipment][Q15] This article is limited to the verified MY25 Premium scope.[Model-year supporting source][Q29]
Two function names do not establish two separate sensors. Nor does DFM identify a camera directly filming the driver: the original explicitly says Indirect.
The original alert is more useful than an invented label
At vehicle reception, retain the text, icon, operating context and software or service records. Do not rewrite different alerts as “cabin radar fault”. Any existing repair diagnosis should also be recorded against the original alert.
This article provides no activation tests. A single occurrence or absence of an alert cannot establish normal operation or failure, and an equipment list is not a safety guarantee to rely on.
Procure parts after identifying the specific component
A function name alone does not establish whether the requirement is for a sensor, control component or another item. Obtain the vehicle-specific diagnosis and catalogue identity before checking the supply boundary. Do not borrow cabin monitoring structures from other BYD models to fill in quantities, locations or part numbers.
Scope and verification
This article covers only Australian MY25 BYD DOLPHIN, Premium. The cited function and equipment information is not a fault or replacement criterion.[Scope reference][Q29]
No public data was available in the reviewed material for sensor types, quantities and locations for each function, alert conditions, shared hardware or parts supply; diagnosis and calibration, repair parameters, fault criteria, OE numbers, separate parts availability or interchangeability. [To be verified] Verify compatibility or interchangeability using the VIN and local Australian manufacturer parts catalogue.
For the parts discussed here, use the parts enquiry page.
