2.

Check the continuity between battery current sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 9.

NO

>> Repair or replace harness.

7.

CHECK BATTERY TEMPERATURE INPUT SIGNAL CIRCUIT 2

1.

Turn ignition switch OFF.

2.

Disconnect battery current sensor connector and IPDM E/R connector.

3.

Check the continuity between battery current sensor harness connector and IPDM E/R harness connec-
tor.

Is the inspection result normal?

YES

>> GO TO 8.

NO

>> Repair or replace harness.

8.

CHECK BATTERY TEMPERATURE INPUT SIGNAL CIRCUIT 3

1.

Connect IPDM E/R connector.

2.

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

Is the inspection result normal?

YES

>> GO TO 9.

NO

>> Repair or replace harness.

9.

CHECK BATTERY CURRENT SENSOR

Refer to 

CHG-20, "Component Inspection"

.

Is the inspection result normal?

YES

>> Refer to 

GI-41, "Intermittent Incident"

. If the inspection result of the connector is normal then

replace IPDM E/R. Refer to 

PCS-67, "Removal and Installation"

.

NO

>> Replace battery current sensor.

Diagnosis Procedure

INFOID:0000000010431022

1.

CHECK “B” TERMINAL CONNECTION

1.

Turn ignition switch OFF.

2.

Check if “B” terminal is clean and tight.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair “B” terminal connection.

2.

CHECK “B” TERMINAL CIRCUIT

Check voltage between alternator “B” terminal and ground.

R9M engine

HR engine

K9K engine

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check harness for open between alternator and fusible link.

3.

CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)

1.

Start engine, then engine running at idle and warm.

2.

Check voltage between battery positive terminal and alternator “B” terminal.
