DTC P1564 ICC STEERING SWITCH
DTC P1564 ICC STEERING SWITCH
PFP:25551
Component Description
NBS0054J
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
for the ICC function.
CONSULT-II Reference Value in Data Monitor Mode
NBS0054K
Specification data are reference values.
On Board Diagnosis Logic
NBS0054L
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

ICC steering switch
●
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.
●
Harness or connectors
(The switch circuit is open or shorted.)
