DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-

ing 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 with ignition

switch ON

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

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

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

YES

>> Proceed to 

EC-1094, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000012198617

1.

CHECK BATTERY CURRENT SENSOR POWER SUPPLY

1. Turn ignition switch OFF.

2. Disconnect battery current sensor harness connector.

3. Turn ignition switch ON.

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

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

CHECK SENSOR POWER SUPPLY 2 CIRCUIT

DTC No.

Possible cause

P1551

BAT CURRENT SENSOR
(Battery current sensor circuit 
low input)

An excessively low voltage from the sen-
sor is sent to ECM.

• Harness or connectors

(Battery current sensor circuit is open 
or shorted.)

• Battery current sensor
• Camshaft position sensor
• Camshaft (Intake)
• Starter motor
• Starting system circuit
• Dead (Weak) battery
• Sensor power supply 2 circuit

P1552

BAT CURRENT SENSOR
(Battery current sensor circuit 
high input)

An excessively high voltage from the sen-
sor is sent to ECM.

Perform 

EC-1240, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> Perform the trouble diagnosis for power supply circuit.

NO

>> Repair or replace error-detected parts.

3.

CHECK BATTERY CURRENT SENSOR GROUND CIRCUIT

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 power.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK BATTERY CURRENT SENSOR INPUT SIGNAL CIRCUIT

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

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

YES

>> GO TO 5.

NO

>> Repair or replace error-detected parts

5.

CHECK BATTERY CURRENT SENSOR

Check the battery current sensor. Refer to 

EC-1092, "Component Inspection"

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> Replace battery negative cable assembly.

Component Inspection

INFOID:0000000012198618

1.

CHECK BATTERY CURRENT SENSOR

1. Turn ignition switch OFF.

2. Reconnect harness connectors disconnected.

3. Disconnect battery negative cable.

4. Install jumper cable between battery negative terminal and body

ground.

5. Turn ignition switch ON.

6. Check the voltage between ECM harness connector and

ground.
