: The ECU is typically located behind the glove compartment or on the cowl side of the passenger seat.
Ground-switching outputs that cycle the fuel injectors. You should see battery voltage when the key is on and rapid pulses when cranking.
Below is an organized, actionable reference for the EFI-type Daihatsu Hijet with the EF-SE engine ECU pinout focusing on the “hot” side: power inputs, ignition-switched feeds, fused supplies, and power-switched outputs that remain energized when key is ON or in START. Use this for diagnostics, wiring repair, or adding accessories. Assume left/right connector orientation when facing the ECU; verify with your vehicle wiring diagram and meter before applying power. daihatsu hijet efse ecu pinout hot
Some EF-SE models (like ECU A32 / 89560-B2460) may not support standard OBD-II protocols and require specific diagnostic tools or pin-jumping for blink codes.

If you own a Daihatsu Hijet (S85, S86, S100, or S110 chassis) equipped with the legendary 650cc inline-3 cylinder engine, you already know the struggle. This little kei truck is a workhorse, but when things go wrong, they often go wrong while the engine is hot —that is, at operating temperature or under load.
Permanent 12V backup power for memory storage (DTC codes). Common "Hot" Wiring & Diagnostic Issues Below is an organized, actionable reference for the
Check the lines for system voltage during engine cranking. If voltage is missing, inspect the primary EFI fuse and the main relay contacts. If power is verified but the system remains unresponsive, check for proper crankshaft speed pulses across the N+ and N- terminal junctions. Without clear rotational feedback, the processor will not trigger the grounding pathways for the ignition coils or fuel injectors. Corrupted Sensor Readings
EF-SE ECUs are robust, but the is often the culprit. Electrical issues account for approximately 90% of Hijet problems—corroded connectors, broken wires, and failed relays are far more common than ECU failure.
