Controls the common rail system, including the Supply Control Valve (SCV) and fuel injectors.
Constant power pins that maintain ECU memory.
While specific wire colors can vary by production year, the 4HL1-1 ECU pinout generally breaks down into these critical circuits:
Multiple signal pins to ensure redundancy and safety in throttle control. 3. Actuator Outputs (Control)
Signals the ECU to wake up when the key is turned.
Resistance-based sensors that help the ECU adjust fuel for cold starts.
