.

DTC CONFIRMATION PROCEDURE

1.

PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to 

EC-378, "Component Function Check"

.

NOTE:

Use component function check to check the overall function of the battery current sensor circuit. During this

check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

EC-379, "Diagnosis Procedure"

.

Component Function Check

INFOID:0000000009429310

1.

PRECONDITIONING

TESTING CONDITION:

• Before performing the following procedure, confirm that battery voltage is more than 12.8V at idle.

• Before performing the following procedure, confirm that all load switches and A/C switch are turned

OFF.

>> GO TO 2.

2.

PERFORM COMPONENT FUNCTION CHECK

With CONSULT

1. Start engine and let it idle.

2. Select “BAT CUR SEN” in “DATA MONITOR” mode with CONSULT.

3. Check “BAT CUR SEN” indication for 10 seconds.

“BAT CUR SEN” should be above 2,300mV at least once.

Without CONSULT

1. Start engine and let it idle.

2. Check the voltage between ECM harness connector and ground.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

EC-379, "Diagnosis Procedure"

.

DTC No.

3.

CHECK BATTERY CURRENT SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between battery current sensor harness connector and ECM harness connector.

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

YES

>> GO TO 4.

NO

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

4.

CHECK BATTERY CURRENT SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1. Check the continuity between battery current sensor harness connector and ECM harness connector.

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

YES

>> GO TO 5.

NO

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

5.

CHECK BATTERY CURRENT SENSOR

Refer to 

EC-380, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Replace battery negative cable assembly.

Diagnosis Procedure

INFOID:0000000009020874

1.

CHECK ASCD STEERING SWITCH CIRCUIT

 With CONSULT

1. Turn ignition switch ON.

2. Select “MAIN SW”, “CANCEL SW”, “RESUME/ACC SW” and “SET SW” in “DATA MONITOR” mode of

“ENGINE” using CONSULT.

3. Check each item indication as per the following conditions.

DTC No.

DTC detecting condition

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
