Actually Smart Summon (ASS)
On HW4 vehicles, the firmware enables Actually Smart Summon without EU regulatory restrictions.
How It Works
The firmware sets the UI_hardCoreSummon bit in CAN message 1021, mux 1, which removes the EU-imposed limitation on Smart Summon functionality.
CAN Message Details
| CAN ID | Mux | Bit | Value | Signal |
|---|---|---|---|---|
| 1021 | 1 | 47 | 1 | UI_hardCoreSummon |
Requirements
- HW3/4 vehicle only — this feature is not available on Legacy
- Active FSD subscription or purchase
- Vehicle firmware that supports Actually Smart Summon
note
This feature is automatically enabled on HW3/4 builds. No additional configuration is needed.
