For ASIL‑B and higher ECUs, repacking must:
Violation: Repacking a safety‑critical sensor next to a high‑dI/dt injector driver violates ISO 26262‑5 (freedom from interference).
| Artifact | Purpose | |----------|---------| | Repack mapping table | Old pin → New pin → Function | | Adjacency matrix | Pairs of pins that must never be adjacent | | Return path analysis | For each high-speed pin | | Pin stress simulation | Current density per pin (W/cm²) | | Test pin allocation | Boundary scan, ICT, debug | | Harness compatibility report | Connector locking, wire gauge, seal |
"Repack" is industry jargon for transplanting the internal logic board of an ECU into a different mechanical housing. Why do this?
There are three primary scenarios requiring a repack:
