(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.)

(Exhaust valve timing control position
sensor circuit is open or shorted.)
(Accelerator pedal position sensor 2
circuit is open or shorted.)
(Turbocharger boost sensor circuit is
open or shorted.)
(Engine oil pressure sensor circuit is
open or shorted.)

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 CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Check harness connector for short to power and short to ground, between the following terminals.
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-410, "Component Inspection"
.
Is the inspection result normal?
YES
>> Check intermittent incident. Refer to
GI-43, "Intermittent Incident"
.
NO
>> Replace battery negative cable assembly. Refer to
.

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.
