"""Some Hyundai radars can be reconfigured to output (debug) radar points on bus 1.
|
|
Reconfiguration is done over UDS by reading/writing to 0x0142 using the Read/Write Data By Identifier
|
|
endpoints (0x22 & 0x2E). This script checks your radar firmware version against a list of known
|
|
firmware versions. If you want to try on a new radar make sure to note the default config value
|
|
in case it's different from the other radars and you need to revert the changes.
|
|
|
|
After changing the config the car should not show any faults when openpilot is not running.
|
|
These config changes are persistent accross car reboots. You need to run this script again
|
|
to go back to the default values.
|
|
|
|
USE AT YOUR OWN RISK! Safety features, like AEB and FCW, might be affected by these changes."""
