Limitations: This viewer is intended for inspection, debugging, and educational use. CAN logs may contain vendor-specific conventions, CAN FD frames, diagnostic traffic, J1939 messages, remote frames, error frames, and nonstandard ASC variants. Parsed values should be independently validated before being used for engineering, safety, calibration, compliance, or production decisions.
