For most of the Toyotas, longitudinal signal (0x343) can be intercepted through ADAS camera, however, there are some exceptions.
Radar ACC Filter (aka Radar Relay) is a CAN Filter that enables openpilot longitudinal control on some Toyota vehicles such as Camry, C-HR, Avalon and some new 2022 RAV4.
Eric Day has developed a more advanced + cheaper approach called canfilter, however, it requires some extensive modification on openpilot.
This approach uses a spare panda device I got at home with wocsor's smart_dsu firmware, works like a charm.
- a white panda, you can get it from comma.ai (grey panda is fine too).
- SmartDSU firmware.
- OBD-2 Female Connector
- 12520 connector
- 12519 connector
- 120ohm resistor
- soldering tools
