P1564 ASCD STEERING SWITCH
P1564 ASCD STEERING SWITCH
Component Description
INFOID:0000000006158856
ASCD steering switch has variant values of electrical resistance for each button. ECM reads voltage variation
of switch, and determines which button is operated.
On Board Diagnosis Logic
INFOID:0000000006158857
• This self-diagnosis has the one trip detection logic.
• The MIL will not light up for this self-diagnosis.
NOTE:
If DTC P1564 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer to
.

ASCD steering switch
• An excessively high voltage signal from the ASCD
steering switch is sent to ECM.
• ECM detects that input signal from the ASCD steer-
ing switch is out of the specified range.
• ECM detects that the ASCD steering switch is stuck
ON.
• Harness or connectors
(The switch circuit is open or
shorted.)
• ASCD steering switch
• Combination switch (spiral ca-
ble)
• ECM
