Hijet Efse Ecu Pinout Hot ((exclusive)) - Daihatsu
Daihatsu Hijet EF-SE (typically found in S200 and S210 series), the ECU pinout is essential for diagnosing EFI issues or performing engine swaps. The EF-SE is a Single Overhead Cam (SOHC) engine often paired with a 2-plug ECU configuration. Live To Dai Core ECU Pinout (22-Pin Connector)
Based on common EF-series technical data, the primary 22-pin connector (Plug 1) typically follows this configuration when viewed from the wire-entry side with the clip on top: Live To Dai Pin 1 (E1): Main Engine Ground. Pin 2 (VC):
Sensor Reference Voltage (typically 5V for MAP/Throttle sensors). Pin 3 (PIM): Intake Manifold Pressure Sensor signal. Pin 4 (THW): Water Temperature Sensor signal. Pin 5 (N+): Engine Speed Signal (Crank/Distributor positive). Pin 6 (IDL): Idle Switch signal. Pin 7 (SPD): Vehicle Speed Sensor input. Pin 11 (+B1): Switched Power Supply (Ignition ON). Pin 12 (E2): Sensor Ground. Pin 13 (OX): cap O sub 2 ) Sensor signal. Pin 14 (THA): Intake Air Temperature Sensor signal. Pin 15 (T): Test Terminal (for diagnostic code retrieval). Pin 16 (N-): Engine Speed Signal negative. Pin 18 (AC): Air Conditioning signal. Pin 22 (+B2): Secondary Power Supply.

) when probing ECU terminals to avoid internal circuit damage. Common Components for EF-SE
If you are troubleshooting, these specific parts are frequently linked to the ECU's performance in the S200P/S210P models: Fuel Injectors:
Uses specific S200P-compatible injectors (Part: 23250-97204-000). Main ECU Unit:
Often labeled as Fujitsu Ten or Denso (Common Part: 89560-series). Spark Plugs: Standard NGK BKR6E-11 or equivalent. Yokohama Motors JDM OEM Auto Parts

The Daihatsu Hijet equipped with the EF-SE engine uses a specific Engine Control Unit (ECU) pinout configuration common in various S200-series mini trucks and vans manufactured between 1999 and 2009. These systems typically feature a multi-plug connector setup—often a 22-pin or similar multi-row configuration—to manage fuel injection, ignition, and sensor feedback. Core EF-Series ECU Pin Functions
While specific wire colors can vary between models like the Hijet S200P (truck) and S200V (van), the EF-series ECUs generally follow this standardized pin logic for essential engine operation: Power and Ground
+B / +B2: Main power supply from the EFI relay, active when the ignition is ON.
BATT: Constant battery backup power used to store diagnostic codes and memory.
E1 / E01: Main ECU grounds, typically connected to the intake manifold or engine block. Sensor Inputs
PIM (Pressure Intake Manifold): Signal from the MAP sensor to determine engine load.
THW (Water Temperature): Input from the coolant temperature sensor for fuel enrichment.
VC: 5V reference power supply provided by the ECU to the sensors.
N+ / NE: Crankshaft or distributor signal used to calculate engine RPM and timing. Daihatsu Hijet EF-SE (typically found in S200 and
OX: Signal from the Oxygen sensor for closed-loop fuel control. Control Outputs #10 / #20: Injector control pulses.
IGT / IGF: Ignition trigger and feedback signals to the ignition coils.
FC (Fuel Control): Signal sent to the fuel pump relay to prime and run the pump.
W (Warning): Controls the "Check Engine" light (Malfunction Indicator Lamp) on the dashboard. Quick Diagnosis Guide
If you are troubleshooting a "no-start" or "no-spark" condition on an EF-SE Hijet, verify these critical pins:
Check Power: Use a multimeter to confirm +B has battery voltage when the key is ON.
Verify Ground: Ensure E1 has less than 0.1 ohms of resistance to the vehicle chassis.
Signal Testing: During cranking, the N+ (NE) pin should show a pulsing voltage signal; without this, the ECU will not trigger injectors or spark.

Step-by-Step: How to Hot Probe Your EFSE ECU
You searched for "hot pinout," so here is how to test these circuits safely without frying your $500 ECU.
Tools needed: Digital multimeter (DMM), back-probe pins (or paperclips), wiring diagram.
Do NOT: Use a screwdriver or large test light on ECU pins. Low-current circuits will be destroyed.
Procedure:
- Ground Check: Set DMM to Ohms (Ω). Place black lead on chassis negative. Probe Pin B2 and Pin B4. You need 0.1 ohms or less. Anything higher means clean your chassis ground strap.
- Constant Hot: Set DMM to DC Volts (20V scale). Black lead to ground. Probe Pin B1. You must have >11.5V (engine off). If not, chase the White/Red wire back to the battery.
- Switched Hot: Turn key to "ON" (do not start). Probe Pin B3. You should see battery voltage. Turn key off. Voltage should drop to 0V. If it stays on, your ignition switch is faulty.
- 5V Reference Test: Key ON. Probe Pin C1 (TPS 5V). You should see exactly 4.8V to 5.2V. If you see 0V, unplug the TPS and MAP sensor. If the voltage returns, one of those sensors is internally shorted.

4. To identify without a diagram:
- Use a multimeter, NOT a test light (test lights can blow ECU drivers)
- Measure for constant 12V (key off) – those are battery feeds
- Measure for 12V with key ON – ignition feeds
- Do NOT apply external power to unknown pins
