The subject line mentions "hot," which is the most common complaint with the Hijet EFSE system. Many owners find their truck starts perfectly cold but refuses to start after driving for 20 minutes and turning it off (a classic heat-soak issue).
Check the main EFI Relay socket and the primary ignition wiring loom underneath the dashboard. Corrosion on these pins causes voltage drops, meaning the ECU might receive under 9V and automatically shut down. 2. Missing Reference Voltage ( VC )
This is a specific request for the of a Daihatsu Hijet with the EFSE engine (often found in the S85 / S86 / S100 series Hijet vans/pickups, mid-1990s to early 2000s). "Hot" likely means you want the live signal info or critical pins (power, grounds, ignition, injector, distributor/igniter, sensors, CEL, fuel pump).
Heat is the EFSE ECU’s nemesis. The ECU is often mounted on the firewall or near the heater core. Over time, thermal cycles cause:
First, know your engine. The is a 660 cc (0.66-liter) SOHC 3-cylinder gasoline engine producing 33 kW (44 hp) at 5,900 rpm and 57 N·m (42 lb·ft) of torque at 3,600 rpm . It uses a 2-valve-per-cylinder design and electronic fuel injection. This engine powered S200P, S210P, S200C, S210C, S320V, and S330V chassis codes, including both 2WD/4WD and manual/automatic transmissions. daihatsu hijet efse ecu pinout hot

ECU failures are rare. Before condemning your ECU, verify:
: When troubleshooting a no-start or rough idle, use a high-impedance multimeter (>10 kΩ/V) to verify that the pins show 12V when the ignition is on. Diagnostic Codes
You searched for "hot pinout," so here is how to test these circuits safely without frying your $500 ECU. The subject line mentions "hot," which is the
Measures engine load.
For serious performance builds (especially EF-DET turbo swaps or other engine conversions), replacing the factory ECU with a programmable unit like Link, MOTEC, or HKS Power FC provides unlimited tuning flexibility. However, this requires building a custom wiring harness and extensive dyno tuning.
The Daihatsu Hijet equipped with the (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. Core ECU Pinout Configuration (EF-Series)
