The Electronic Control Unit (ECU) manages the Electronic Fuel Injection (EFI) system by processing signals from various sensors and controlling actuators like injectors and the fuel pump. In many Hijet models, the ECU is located behind the dashboard or glove compartment area. Critical ECU Pinout Terminals
Slide a fine sewing needle or backprobe tool along the wire insulation, underneath the rubber weather seal, until it touches the metallic terminal inside the plastic plug.
Check the voltage at Pin 2 (VC) against Pin 12 (E2) when the engine bay is hot. If the voltage drops below 4.75V, the internal regulator chip inside the ECU casing is failing, requiring professional circuit board repair or ECU replacement. daihatsu hijet efse ecu pinout hot
: Often caused by faulty alternators or short circuits in the loom.
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. The Electronic Control Unit (ECU) manages the Electronic
The Daihatsu Hijet is a small commercial vehicle produced by Daihatsu, a Japanese automaker. The EF-SE engine is a 660cc, 3-cylinder engine used in the Hijet from 1994 to 1998.
"Look," Kenji pointed to the screen. "Pin 12 isn't the ground; it’s the ignition trigger. And Pin 24? That’s the main 12V feed from the EFI relay." Check the voltage at Pin 2 (VC) against
Before diving into the wiring diagram, let’s establish context. The EFSE engine is a liquid-cooled, inline-3 cylinder, 12-valve SOHC unit found in Hijet vans and trucks from the late 1990s to early 2000s (specifically the S83 chassis). It utilizes electronic fuel injection (EFI) managed by a Denso ECU (typically part numbers beginning with 89661-...).
