1.

CHECK BATTERY CURRENT SENSOR

1. Turn ignition switch OFF.

2. Reconnect harness connectors disconnected.

3. Disconnect battery negative cable (1).

4. Install jumper cable (A) between battery negative terminal and

body ground.

5. Turn ignition switch ON.

6. Check the voltage between ECM harness connector terminals

as per the following.

Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to 

PG-4, "How to Handle Battery"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace battery negative cable assembly.

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.

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is more than 8 V at idle.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Start engine and wait at least 10 seconds.

2. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> Go to 

EC-372, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009620498

1.

CHECK GROUND CONNECTION

1. Turn ignition switch OFF.

2. Check ground connection E15. Refer to Ground Inspection in 

GI-48, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK BATTERY CURRENT SENSOR POWER SUPPLY

1. Disconnect battery current sensor harness connector.

2. Turn ignition switch ON.

3. Check the voltage between battery current sensor harness connector and ground.

DTC No.

Possible cause

P1553

Battery current sensor perfor-
mance

The signal voltage transmitted from the 
sensor to ECM is higher than the amount 
of the maximum power generation.

• Harness or connectors

(Battery current sensor circuit is open 
or shorted.)
(APP sensor 2 circuit is open or short-
ed.)
(EVAP control system pressure sensor 
circuit is shorted.)
[Crankshaft position sensor (POS) cir-
cuit is shorted.]
(Refrigerant pressure sensor circuit is 
shorted.)

• Battery current sensor
• Accelerator pedal position sensor 

(APP sensor 2)

• EVAP control system pressure sensor
• Crankshaft position sensor (POS)
• Refrigerant pressure sensor

GI-45, "Intermittent Incident"

.

NO

>> Repair or replace error-detected parts.

4.

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 5.

NO

>> Repair or replace error-detected parts.

5.

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 6.

NO

>> Repair or replace error-detected parts.

6.

CHECK BATTERY CURRENT SENSOR

Check battery current sensor. Refer to 

EC-377, "Component Inspection"

.
