DTC P1564 ICC STEERING SWITCHPFP:25551
Component DescriptionNBS005M7
ICC 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 ACS-6, "
DESCRIPTION" for the ICC function.
CONSULT-II Reference Value in Data Monitor ModeNBS005M8
Specification data are reference values.
On Board Diagnosis LogicNBS005M9
This self-diagnosis has the one trip detection logic.
The MIL will not light up for this diagnosis.
NOTE:
If DTC P1564 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer to
EC-1190, "

An excessively high voltage signal from the
ICC steering switch is sent to ECM.
ECM detects that input signal from the ICC
steering switch is out of the specified range.
ECM detects that the ICC steering switch is
stuck ON.

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.
Diagnostic ProcedureNBS005MC
1. CHECK GROUND CONNECTIONS
