circuit low input

ECM detects that the ASCD steering switch is
stuck ON.
Harness or connectors
(The switch circuit is open or shorted.)

DTC P0580, P0581 ASCD STEERING SWITCH

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.
