CAN Error: Check Connections
Connections are fine but the device gives the error listed above. The device is getting information from my car such as the brakes, so I know it is communication on some level, but I cannot engage OP.
More information please like what car and type of harness? and did u just get op? Is vanilla working?
Videos are helpful. Try to provide as much information as possible please

2019 Hyundai Santa Fe Limited Hyundai D Harness Vanilla works fine This is my first time trying this fork. I installed using: git remote add neokii https://github.com/neokii/op4.git && git fetch --all && git checkout hkg_084_dev
Latest 085 update still has his car broken. Any ideas?
Turn off long control in the settings. Settings -> Community -> Turn off "Enable HKG Long Control"
If scc is on bus 0, long control does not work.
Long Control does work. It works on this fork: https://github.com/andy741217/dragonpilot
But it is only vision long. Orical and I think it has something to do with the radar.
The latest update did not fix the issue. CAN Error: Check Connections still present
His car works on OpenPilot long without moving scc off of bus 0 to 2 on this fork https://github.com/andy741217/dragonpilot
