DTC P0580, P0581 ASCD STEERING SWITCHPFP:25551
Component DescriptionEBS01FDT
ASCD steering switch has variant values of electrical resistance for each button. ECM reads voltage variation
of switch, and determines which button is operated.
Refer to EC-1690, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)" for the ASCD function.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
