P1564 ASCD STEERING SWITCH

Description

INFOID:0000000001671042

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-61, "System Diagram"

 for the ASCD function.

DTC Logic

INFOID:0000000001671043

DTC DETECTION LOGIC

NOTE:
If DTC P1564 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer to

EC-215, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

3.

Press MAIN switch for at least 10 seconds, then release it and wait at least 10 seconds.

4.

Press CANCEL switch for at least 10 seconds, then release it and wait at least 10 seconds.

5.

Press RESUME/ACCELERATE switch for at least 10 seconds, then release it and wait at least 10 sec-
onds.

6.

Press SET/COAST switch for at least 10 seconds, then release it and wait at least 10 seconds.

7.

Check DTC.

Is DTC detected?

YES

>> Go to 

EC-267, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000001671044

 With CONSULT-III

1.

Turn ignition switch ON.

DTC No.

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

P1564 ASCD STEERING SWITCH

2.

Select “MAIN SW”, “CANCEL SW”, “RESUME/ACC SW” and “SET SW” in “DATA MONITOR” mode with
CONSULT-III.

3.

Check each item indication under the following conditions.

 Without CONSULT-III

1.

Turn ignition switch ON.

2.

Check the voltage between ECM harness connector terminals as follows.

Is the inspection result normal?

YES

>> GO TO 8.

NO

>> GO TO 3.

3.

CHECK ASCD STEERING SWITCH GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Disconnect combination switch harness connector M30.

4.

Check the continuity between combinarion switch and ECM harness connector.

5.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 4.

4.

DETECT MALFUNCTIONING PART

Check the following.
• Harness connectors M69, E7
• Combination switch (spiral cable)
• Harness for open and short between ECM and combination switch

>> Repair open circuit or short to ground or short to power in harness or connectors.
