ASCD Steering Switch
FUNCTIONS WITHIN THE SYSTEM
The ECM controls the ASCD based on the signal that is transmitted from the ACSD steering switch.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
The ACSD steering switch transmits the signals of the switches operated by the driver to the ECM.
INDIVIDUAL OPERATION
Each switch circuit has a resistor with a different resistance connected in series. The ECM reads the voltage values that are transmitted from each switch and split by the resistors, and detects which button is operated. The ECM reads the voltage values that are transmitted from each switch and split by the resistors, and detects which button is operated.
