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
