NOTE
Gasoline NATS architecture. Compared to Supplement-VI EL-6045:
• ECM authorisation pin moved from 26 (Supplement-VI) to 88 (Supplement-VII) — ECM pinout was remapped.
• Super-lock CU added as a NATS-authorisation peer (Supplement-VI didn't have this link).
• Audio chain unchanged.
IMMU pin layout unchanged: 1=ECM, 2=Audio, 3=SLCU (new), 4=GND, 6=Security indicator, 7=IGN, 8=BAT.
Variant tags SL and AU on this page document which optional NATS peers are present in each trim.
WARNING
Super-lock CU now also relies on NATS authorisation — if NATS is faulty, super-lock and central-lock may stop working too. Pin 3 fault = stuck locks AND no engine start.
