While specific connector layouts can vary slightly by manufacturing year (e.g., S200P vs. S210P), the following terminal codes are standard for Daihatsu EF-series engine management: Power and Ground Terminals +B / +B1 / +B2 : Main power supply from the EFI relay. : Constant battery power for memory back-up. E1 / E01 / E02 : Main chassis and sensor grounds. Sensor Inputs : Manifold Absolute Pressure (MAP) sensor signals. : Engine coolant temperature sensor signal. daihatsu hijet efse ecu pinout hot

• Solder joint cracks on the main relay driver and injector transistors.
• Capacitor leakage (common in early 1990s Denso units), which skews the 5V reference.
• Connector expansion, leading to high resistance on ground pins (E01, E02).

The Daihatsu Hijet equipped with the EF-SE engine (a 659cc, 3-cylinder, non-turbo SOHC unit) uses a specific Engine Control Unit (ECU) pinout configuration that is critical for engine swaps, diagnostics, or repairing electrical faults. Proper identification of these pins is essential to avoid shorting the system, which can blow the 15-amp engine fuse or damage the unit permanently.
