If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to
. Also,
replace the engine oil. Refer to
.
1.
Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to
MA-11, "Anti-Freeze Coolant Mixture Ratio"
2.
After refilling coolant, run engine to ensure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.
PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to
EC-425, "Component Function Check"
.
NOTE:
Use component function check to check the overall function of the cooling fan. During this check, a DTC might
not be confirmed.

P1550 BATTERY CURRENT SENSOR
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.

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.
Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to
PG-91, "How to Handle Battery"
.
