P1564 ASCD STEERING SWITCH

P1564 ASCD STEERING SWITCH

Component Description

INFOID:0000000009481078

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 

CCS-3

 for the ASCD function.

On Board Diagnosis Logic

INFOID:0000000009481079

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

EC-347

.

DTC Confirmation Procedure

INFOID:0000000009481080

NOTE:

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at

least 10 seconds before conducting the next test. 

 WITH CONSULT

1. Turn ignition switch ON and wait at least 10 seconds.
2. Press MAIN switch for at least 10 seconds, then release it and wait at least 10 seconds.
3. Press CANCEL switch for at least 10 seconds, then release it and wait at least 10 seconds.
4. Press RESUME/ACCELERATE switch for at least 10 seconds, then release it and wait at least 10 sec-

onds.

5. Press SET/COAST switch for at least 10 seconds, then release it and wait at least 10 seconds.
6. Check DTC.
7. If DTC is detected, go to 

EC-384, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT” above.

Diagnosis Procedure

INFOID:0000000009481081

1.

CHECK GROUND CONNECTIONS

1. Turn ignition switch OFF.

2. Loosen and retighten two ground screws on the body.

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
