System ChartEBS0116V
*1: The input signal is sent to the ECM through CAN communication line.
*2: The output signal is sent from the ECM through CAN communication line.
Fuel Injection Control SystemEBS0116W
SYSTEM DESCRIPTION
Three types of fuel injection control are provided to accommodate engine operating conditions; normal control,
idle control and start control. The ECM determines the appropriate fuel injection control. Under each control,
the amount of fuel injected is adjusted to improve engine performance.
Pulse signals are sent to fuel injectors according to the input signals to adjust the amount of fuel injected to
preset value.
START CONTROL
Input/Output Signal Chart
When the ECM receives a start signal from the ignition switch, the
ECM adapts the fuel injection system for the start control. The
amount of fuel injected at engine starting is a preset program value
in the ECM. The program is determined by the engine speed, engine
coolant temperature and fuel rail pressure.
For better startability under cool engine conditions, the lower the
coolant temperature becomes, the greater the amount of fuel
injected. The ECM ends the start control when the engine speed
reaches the specific value, and shifts the control to the normal or idle
control.

DECELERATION CONTROL
Input/Output Signal Chart
The ECM sends a fuel cut signal to the fuel injectors and fuel pump during deceleration for better fuel effi-
ciency. The ECM determines the time of deceleration according to signals from the accelerator pedal position
sensor and crankshaft position sensor.
Fuel Injection Timing Control SystemEBS0116X
DESCRIPTION
The target fuel injection timing in accordance with the engine speed and the fuel injection amount are recorded
as a map in the ECM beforehand. The ECM determines the optimum injection timing using sensor signals
accordance with the map.
Air Conditioning Cut ControlEBS0116Y
INPUT / OUTPUT SIGNAL CHART
*: The input signal is sent to the ECM through CAN communication line.
SYSTEM DESCRIPTION
This system improves acceleration when the air conditioner is used.
When the accelerator pedal is fully depressed, the air conditioner is turned off for a few seconds.
When engine coolant temperature becomes excessively high, the air conditioner is turned off. This continues
until the engine coolant temperature returns to normal.
Fuel Cut Control (At No Load & High Engine Speed)EBS0116Z
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
speed is over 2,800 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies
based on engine speed. Fuel cut will be operated until the engine speed reaches 1,500 rpm, then fuel cut will
be cancelled.
NOTE:
This function is different from deceleration control listed under EC-885, "
Fuel Injection Control Sys-
tem" .
