Tools of UDS Toolbox
	Description		Read-only	Idempotent	Open world
`analyze_trace`Analyze a whole CAN trace of a UDS diagnostic or flash session and say what went wrong. Accepts candump logs, Vector ASC, PEAK TRC (1.x/2.x), SavvyCAN or python-can CSV pasted as text, and those plus Vector BLF, Wireshark pcap/pcapng (SocketCAN) and ASAM MF4 bus logging uploaded as a file. Reassembles ISO-TP, pairs requests with responses (including 0x78 responsePending), measures P2/P2*, follows sessions and security access, reconstructs RequestDownload/TransferData into an image with CRC32, extracts identification DIDs, and returns a root-cause finding with the frames that show it. Shows an interactive timeline.	Analyze a whole CAN trace of a UDS diagnostic or flash session and say what went wrong.

`build_uds_request`Build a UDS request as hex with an annotated breakdown. Services: session, ecu_reset, read_did, write_did, security_seed, security_key, tester_present, routine, request_download, transfer_data, transfer_exit, clear_dtc, read_dtc, control_dtc, comm_control, raw. Numeric strings are hex.	Build a UDS request as hex with an annotated breakdown.

`decode_dtc`Convert a 3-byte UDS DTC to the SAE J2012 style code (P/C/B/U + digits) plus failure type byte, or the reverse ("U0073-00" to hex). With a status byte, explains each of the 8 DTC status bits.	Convert a 3-byte UDS DTC to the SAE J2012 style code (P/C/B/U + digits) plus failure type byte, or the reverse ("U0073-00" to hex).

`decode_isotp`Reassemble ISO-TP (ISO 15765-2) messages from CAN frames, per CAN id, and decode each as UDS. Reports frame types (SF/FF/CF/FC), flow-control BS/STmin, sequence-number errors, interrupted messages, padding, and N_Bs/N_Cr/STmin timing warnings when timestamps (ms) are given. Accepts a frame list or a candump text dump.	Reassemble ISO-TP (ISO 15765-2) messages from CAN frames, per CAN id, and decode each as UDS.

`decode_uds`Decode a UDS (ISO 14229-1) PDU from hex: request, positive or negative response. Names the service, sub-function (and suppressPosRsp bit), DID/RID/address fields, and for negative responses the NRC with meaning and typical cause. Unknown SIDs and NRCs are labelled, not rejected.

No	Yes	Yes	No
`uds_reference`Short UDS reference with ISO 14229-1 clause pointers (paraphrased). Topics: a service ID (0x27) or name, an NRC (0x78 or "nrc 78"), a DID (F190) or RID (FF00), timing (p2, p2*, s3), sessions, security (0x27 vs 0x29), reprogramming_sequence. Unknown topics return a topic list.	Short UDS reference with ISO 14229-1 clause pointers (paraphrased).

`udslib_integration`Plan how to integrate the UDSLib C stack (ISO 14229 UDS server/client for embedded ECUs): which repo files to take, Kconfig/config hints, an init skeleton, the closest example, and the license terms (free noncommercial / commercial). UDSLib speaks ISO-TP over CAN/CAN-FD; DoIP is not supported.
