Description

INFOID:0000000001693375

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 

EC-424, "System Diagram"

 for the ASCD function.

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
