P1564 ASCD STEERING SWITCH
P1564 ASCD STEERING SWITCH
Description
INFOID:0000000001116278
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
INFOID:0000000001116279
DTC DETECTION LOGIC
NOTE:
If DTC P1564 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer to

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

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 and ground.
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 M352.
4.
Check the continuity between ASCD steering 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 M77, E105
• Combination switch (spiral cable)
• Harness for open and short between ECM and ASCE steering switch
>> Repair open circuit or short to ground or short to power in harness or connectors.
