Accelerator Pedal Control
Purpose: To control the engine speed in response to
stepping amount of the accelerator pedal.
Operation:
1. MC converts the input value from the accelerator
pedal into the target engine speed and transmits it
to ECM.
2. ECM controls the engine speed in response to the
target engine speed.
NOTE: Output value of the accelerator pedal sen-
sor is 0.5 V to 4.5 V.
NOTE: In case the accelerator pedal sensor be-
comes abnormal, MC makes backup con-
trol, and the engine speed is fixed at about
1100 min
-1
.
NOTE: In case MC becomes out of order, or CAN
fails, ECM makes backup control, and the
engine speed is fixed at about 1100 min
-1
.
NOTE: In case MC becomes out of order with the
accelerator remaining normal, control of
the engine speed is possible by connecting
the accelerator pedal sensor wires directly
to ECM.
