# UDS Diagnostic IDs

Table of which *diagnostic* CAN IDs correspond to which modules. (Note: Diagnostic CAN IDs are totally separate from CAN messaging during normal vehicle operation.)

Each module has an `rxid` which receives UDS messages and it responds by sending messages to a `txid`. `rxid == txid + 8`.
