Diagnosis Procedure

INFOID:0000000012198630

1.

CHECK ASCD STEERING SWITCH CIRCUIT

With CONSULT

1. Turn ignition switch ON.

Possible cause

P1564

ASCD SW
(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

(ASCD steering switch circuit is open 
or shorted.)

• ASCD steering switch
• ECM

P1564 ASCD STEERING SWITCH

Without CONSULT

1. Turn ignition switch ON.

2. Check the voltage between ECM harness connector terminals.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> GO TO 2.

2.

CHECK ASCD STEERING SWITCH GROUND CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Disconnect combination switch (spiral cable) harness connector.

4. Check the continuity between combination switch (spiral cable) and ECM harness connector.

5. Also check harness for short to ground and to power.
Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace error-detected parts.

3.

CHECK ASCD STEERING SWITCH INPUT SIGNAL CIRCUIT

1. Check the continuity between ECM harness connector and combination switch.

2. Also check harness for short to ground and to power.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

DTC DETECTION LOGIC

NOTE:

• If DTC P1572 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer

to 

EC-1052, "DTC Logic"

.

• This self-diagnosis has the one trip detection logic. When malfunction A is detected, DTC is not

stored in ECM memory. And in that case, 1st trip DTC and 1st trip freeze frame data are displayed.

1st trip DTC is erased when ignition switch OFF. And even when malfunction A is detected in two

consecutive trips, DTC is not stored in ECM memory.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

NOTE:

Procedure for malfunction B is not described here. It takes extremely long time to complete procedure for mal-

function B. By performing procedure for malfunction A, the incident that causes malfunction B can be

detected.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A

1. Start engine.

2. Press MAIN switch and make sure that CRUISE indicator is displayed in combination meter.

3. Drive the vehicle for at least 5 consecutive seconds as per the following conditions.

CAUTION:

Always drive vehicle at a safe speed.

NOTE:

This procedure may be conducted with the drive wheels lifted in the shop or by driving the vehicle.

If a road test is expected to be easier, it is unnecessary to lift the vehicle.

4. Check DTC.
Is DTC detected?

YES

>> Proceed to 

EC-1113, "Diagnosis Procedure"

.

NO

>> GO TO 3.

DTC No.

A)

When the vehicle speed is above 30 km/h 
(19 MPH), ON signals from the stop lamp 
switch and the brake pedal position switch 
are sent to the ECM at the same time.

• Harness or connectors

(Stop lamp switch circuit is shorted.)
(Brake pedal position switch circuit is shorted.)

• Stop lamp switch
• Brake pedal position switch
• Incorrect stop lamp switch installation
• Incorrect brake pedal position switch installa-

tion

• ECM
