| Area | 0x0f000000 | 0x01000000 | GLOBAL |

| Ordinal | 0x0000ffff | 0x00000f06 | 0xf06 |
Reading it from an app
This property is defined in the HAL but is not exposed as a constant in android.car.VehiclePropertyIds, so it is not reachable through CarPropertyManager from an ordinary app. It is used by the platform, or by vendor code running with system privileges.
