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
.

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

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
