DTC P1564 ASCD STEERING SWITCH
Wiring Diagram
INFOID:0000000001702955
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.
