Understanding the Wiring Diagram and ECU Pinout for Daihatsu L9: A Comprehensive Guide Daihatsu Move L9 (1998–2002) utilizes various ECU pinouts
For detailed schematics of specific sub-systems like the ABS or A/C, you can refer to specialized Daihatsu Service Manuals or Workshop Guides. Crankshaft position sensor (CKP): Pin 5 (Connector B)
+B / +B2: Main ECU power supply from the EFI relay, active when the ignition is ON. BATT: Constant battery backup power for memory. E1 / E01 / E02: Primary engine grounds. Sensor Inputs: PIM: Intake manifold pressure (MAP sensor) signal. THW: Engine coolant temperature (ECT) sensor signal. THA: Intake air temperature (IAT) sensor signal. VTA / VTHO: Throttle position sensor (TPS) signal. SPD: Vehicle speed sensor (VSS) signal. Actuator Outputs: #10, #20, #30: Fuel injector triggers. IGT1, IGT2, IGT3: Ignition timing signals for the coils. FC / FC1: Fuel pump relay control. W: Check Engine Light (CEL/MIL) output. Wiring Harness Color Codes (L9 JBDET Example)
Most Daihatsu EFI systems from this era share a core set of terminal labels. When inspecting the ECU connectors (typically from the wire side), you will often find these critical pins: Power & Ground: BATT / +B: Constant battery power for memory . IGN / IG1: Switched ignition power to activate the ECU . E1 / GND: Main chassis ground for the control unit . Sensor Inputs: PIM: Intake manifold pressure (MAP sensor) signal . THW: Engine coolant temperature signal . VC: 5V reference voltage output for sensors . SPD: Vehicle speed sensor input . Control Outputs: #10, #20, #30: Fuel injector trigger signals. IGT / IGF: Ignition trigger and fail-safe feedback signals. FP: Fuel pump relay control . Wiring & Inspection Tips
