2025 DOLPHIN Premium cross-traffic braking: do not label FCTB and RCTB as parking sensors

A cross-traffic message while reversing out of a parking space may be written into a parts request as “rear parking sensor”. On Australian MY25 DOLPHIN Premium, retaining the factory function abbreviations helps prevent a braking-related function from being reported as a specific sensor.

FCTB and RCTB are listed as braking functions

The specification table lists Front Cross Traffic Brake and Rear Cross Traffic Brake for Premium. A separate, explicit MY25 Premium entry in the local brand network supports the model-year check.[Factory equipment][R14][Model-year supporting source][R17] This article uses these function descriptions only within that verified equipment overlap.

Brake should not be reduced to an ordinary parking alert. However, the names alone do not identify the sensor combination, installation locations or all participating components.

Record the message before guessing the component

Retain the original instrument or screen message, the vehicle situation and changes before and after repair. Record separately whether a warning appeared, a vehicle action was felt or there was simply a question about function availability. A system abbreviation alone cannot decide replacement of radar, a sensor or a brake component.

Put the original screen message and circumstances first in the record, and list the component diagnosed by the repairer separately. Retain MY25 Premium and the complete FCTB and RCTB names when selecting parts, so that function descriptions and actual component requirements each remain clear.

Scope and verification

This article covers only Australia, MY25 BYD DOLPHIN, Premium; excluding other trims.[Model-year scope][R17] The cited product equipment identifies functions and parts; it is not a fault or replacement criterion.

No public data was available in the reviewed material for sensing component types and locations, activation and exit conditions, braking thresholds, calibration and service parameters; OE numbers, repair parameters, separate parts availability or compatibility and interchangeability. [To be verified] Verify compatibility or interchangeability using the vehicle identification number (VIN) and local Australian manufacturer parts catalogue.

For the parts discussed here, use the parts enquiry page.
