obd_reader.py: - Mode 22 plumbing: ELM.mode22() sends a 16-bit PID request, parses both positive (62 ..) and negative (7F 22 NRC) responses. - --ford runs a small TENTATIVE table of community-sourced Ford 6.0 PIDs (ICP/IPR/FICM/EBP/EOT). All printed with raw bytes for verification. - --pid XXXX probes a single PID and prints multiple candidate decodings (u8, u16, mV, temp, duty) so we can eyeball the right scaling. - --watch [N] streams ATRV + module voltage (PID 0142) for N seconds. Designed for capturing voltage sag during cranking. - --scan AAAA-BBBB brute-force scans Mode-22 PIDs with --scan-log PATH for output. Uses fast ELM timing (ATAT2, ATST19) for ~3.5 PIDs/sec. diagnostics/2026-06-29-no-start/: - Captured cranking voltage trace, full Mode-22 scan (1000-14FF -> 46 hits), and a session writeup. Working hypothesis: not batteries, not fuel -- ICP / FICM / CMP. FICM meter test still owed. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
