Ensure the ECU cover and seals are intact, as the Hijet's under-seat engine placement can expose the unit to moisture.
NE (Engine Speed/Crank Position): This provides the RPM signal. Without this "hot" signal, the ECU will not fire the injectors or spark plugs.
This detailed guide breaks down the architecture of the EF-SE engine control system, maps out vital pin locations, and highlights critical troubleshooting protocols to prevent your ECU from overheating or burning out. Anatomy of the Daihatsu EF-SE ECU Architecture
