ENGINE CONTROL SYSTEM EC-25 [YD (WITH EURO-OBD)] C D E F G H I J K L M A EC DECELERATION CONTROL The ECM sends a fuel cut signal to the fuel injectors and fuel pump during deceleration for better fuel effi- Fuel Injection Timing Control System EBS013J6 DESCRIPTION The target fuel injection timing in accordance with the engine speed and the fuel injection amount are recorded Air Conditioning Cut Control EBS013J7 INPUT / OUTPUT SIGNAL CHART *1: The input signal is sent to the ECM through CAN communication line. SYSTEM DESCRIPTION This system improves acceleration when the air conditioner is used. Fuel Cut Control (At No Load & High Engine Speed) EBS013J8 INPUT/OUTPUT SIGNAL CHART *: The input signal is sent to the ECM through CAN communication line. If the engine speed is above 2,800 rpm under no load (for example, the shift position is neutral and engine NOTE: EC-23, "Fuel Injection Control System" .
