Description

> there is overlap between the “FOME custom” codes and real OBD codes

https://wiki.fome.tech/Limits-And-Protections/Fault-Codes/ -- beware, page update/consistency is manual (and may be lagged)

ex:
- `CUSTOM_PRIMARY_TOO_MANY_TEETH`: `9002`
- `9002 == 0x232A` -> `P232A`
- `CUSTOM_PRIMARY_BAD_TOOTH_TIMING`: `9007`
- `9007 == 0x232F` -> `P232F`
