On S200P/S210P Hijet models, the ECU is typically mounted behind the dashboard on the passenger side (right-hand drive models) or driver side (left-hand drive models). The ECU is a with identifying numbers such as 89560-97D80 or 89560-87532 . The connector layout varies slightly by model year—Daihatsu is notorious for changing pin assignments across production runs.
Depending on the production year, the EF-SE ECU generally ships in a or a later three-plug module . The wiring configuration is designed to monitor atmospheric signals and drive outputs like the fuel pump relay and ignition coils. 🔌 Core ECU Pinout Configuration
Because these compact utility vehicles work hard in harsh conditions, specific connections can build up resistance, creating "hot" spots or overheating points inside the control unit circuitry. This comprehensive wiring guide breaks down the essential pinouts, power sources, and common electrical failures.
