While specific pin locations can vary by year and exact model (e.g., S200V vs. S210P), many Daihatsu EF-series ECUs share standard terminal labels found inside the casing or in factory service manuals. +B1 / +B2: Main power supply from the battery/ignition. E1 / E2: Main ECU grounds. PIM: Pressure Intake Manifold (MAP sensor signal). THW: Water temperature sensor signal. THA: Intake air temperature sensor signal. OX: Oxygen (O2) sensor signal. IDL: Idle switch signal. SPD: Vehicle speed sensor signal. N+ / N-: Engine speed (RPM) or crankshaft position signals. VC: 5V reference voltage for sensors. Pro-Tips for Pinout Troubleshooting
Be careful when mixing looms. For example, some EF-series engines changed Pin 10 from an earth (ground) to a 12V+ line between generations; mixing them can immediately blow the 15-amp engine fuse. daihatsu hijet efse ecu pinout hot
Comprehensive Guide to Daihatsu Hijet EF-SE ECU Pinouts The with the EF-SE engine (a 0.6L non-turbo SOHC 3-cylinder) is a staple of the Japanese mini-truck (Kei truck) world. Understanding its ECU pinout is critical for troubleshooting sensor issues, performing engine swaps, or wiring aftermarket accessories like tachometers or air conditioning relays. Understanding the EF-SE ECU Configuration While specific pin locations can vary by year
The EF-SE engine typically uses a . Depending on the model year (such as the S200 series), the ECU may have different plug configurations, most commonly a 2-plug or 3-plug setup . Common ECU Pin Assignments E1 / E2: Main ECU grounds
If your Hijet stalls when the AC is turned on, check the Idle Up VSV pin. Improper wiring here often causes low RPM or engine stalling during high electrical load. Required Resources
