SFI system - Brake Override System Description When the vehicle is being driven with the accelerator pedal depressed, depressing the brake pedal without releasing the accelerator pedal will activate the brake override system to restrict driving torque. The conditions for activating the brake override system as well as the items that are controlled are explained below.

SFI system - Cranking Holding Function Circuit Description The cranking holding control system provides current to the starter when the ECM detects the ignition switch start signal (STSW). When the ECM performs a firing judgment, the system cuts current to the starter. When an ECM receives the STSW signal, it turns on the ST CUT relay, which prevents flickering of the combination meter, clock, audio system, etc. Also, the ECM sends a signal to the STAR terminal of the ECM. Then the STAR output signal travels through the Park/Neutral Position (PNP) switch to the ST relay, causing the starter to activate.

SFI system - Starter Signal Circuit Description While the engine is being cranked, current flows from terminal ST1 of the ignition switch*1 or terminal STAR of the main body ECU*2 to the park/neutral position switch (for automatic transmission) or clutch start switch (for manual transmission) and also flows to terminal STA of the ECM (STA Signal).

SFI system - Fuel Injector Circuit Description The fuel injectors are located on the intake manifold. They inject fuel into the cylinders based on the signals from the ECM.

Description. Fuel Pump Control Circuit The fuel pump circuit consists of the ECM, fuel pump and fuel pump ECU (which operates the fuel pump). Based on the engine output, the ECM determines the fuel pump speed. The speed is then converted to a duty signal and sent to the fuel pump ECU. Based on the signal sent from the ECM, the fuel pump ECU adjusts the fuel pump operation speed between 3 settings.
