P1564 ASCD STEERING SWITCH
Description
INFOID:0000000001089463
ASCD 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
DTC Logic

Trouble diagnosis
name
DTC detecting condition
Possible cause
P1564
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 steering 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
• ECM
