These functions are typically found in the primary ECU connectors (often labeled A and B) for managing fuel and timing: Pins 1, 3, 5: Battery Power inputs Pins A01, A03: Power Ground (P-GND) Pin 82: T15 (Main Relay Power) Fuel Injection System Pins 31, 46: Injector No. 1 Cylinder (High/Low) Pins 17, 2: Injector No. 2 Cylinder (High/Low) Pins 16, 1: Injector No. 3 Cylinder (High/Low) Pins 32, 47: Injector No. 4 Cylinder (High/Low) Pin 39: Rail Pressure Sensor Engine Timing and Speed Pin 22: Engine Speed Sensor (CRS Position) Pin 14: Camshaft Position Sensor Pin 7: CRS Negative Sensors and Temperature Pin 55: Water Temperature Sensor (CTS) Pin 38: Air Mass Sensor (AMS) Supply Pin 42: Intake Air Temperature Supply Pin 54: Fuel Temperature Sensor Pin 13: Boost Pressure Sensor Supply Communication Pins 62, 61: Controller Area Network (CAN) High and Low Detailed Resources
While specific pin-by-pin numbering can vary slightly based on the truck's manufacturing year (e.g., the 24V FEF63B model), standard configurations include: Power & Ground Battery Power If you are tracking down a no-start condition,
Understanding the view is key to efficient Fuso Canter maintenance. By identifying the correct pins for power, ground, and crucial sensors, you can significantly reduce diagnostic time and ensure the 5.2L engine operates efficiently.

The ECU controls several actuators to manage engine operation:
: Accelerator Position Sensor (APS), Engine Speed Sensor, Rail/Turbo Boost Pressure Sensors.
Nothing. He switched the ignition to the "On" position. He needed the constant 12-volt feed and the switched ignition feed. He focused on the pins that looked slightly larger—manufacturers often used thicker gauge wires for main power.
