СИСТЕМА SFI - Цепь функции полуавтоматического запуска двигателя


DESCRIPTION

The cranking holding control system keeps energizing the ST relay after the ECM detects the starter signal (STSW signal) from the main body ECU until the ECM performs a judgment of "Engine started". Furthermore, the ECM outputs an accessory cut signal (ACCR signal) to the ACC relay during cranking to prevent flickering of the combination meter, clock, audio system, and other areas.
When the ECM detects the STSW signal, the ECM outputs the starter relay drive signal (STAR signal) to the starter relay through the clutch pedal switch assembly, and then the engine is cranked. When the ECM receives a stable engine speed signal (NE signal) (more specifically, when the NE signal reaches a predetermined value), the ECM stops outputting the STAR signal. Also, the ECM monitors the ST relay operating conditions based on the STA terminal voltage status.
