BATTERY
CURRENT SENSOR CALIBRATION <VEHICLES FOR
ARGENTINA>
PURPOSE
The engine-ECU carries out the
electrical generation control according to the charge level
of the battery, based on the battery current sensor signal. To improve
the effect of reducing
the fuel consumption by the electrical generation control, it is
necessary to accurately detect
the charge level of the battery. For this, if the following services are
performed, carry out the
battery current sensor calibration.
- Replacing the battery current sensor
- Replacing the engine-ECU
LEARNING
PROCEDURE
1.After the ignition switch is in LOCK
(OFF) position, disconnect the battery cable
from the negative battery terminal.
2.

Remove the
battery current sensor from the battery cable (Do not disconnect the
battery current
sensor connector).
3.Connect the battery cable without the
battery current sensor to the negative battery
terminal.

Connect the
M.U.T.-III to the diagnosis connector (But do not start the
engine).
5.Turn the ignition switch to the ON
position.
6.Select "MPI/GDI/DIESEL" from System select Screen
of the M.U.T.-III.
7.Select "Special Function" from
MPI/GDI/DIESEL Screen.
8.Select "Learning" from Special
Function Screen.
9.Select "Battery current SNSR.calibration"
from Learning Screen.
10.Start the calibration by pressing the
OK button.
11.Confirm that the M.U.T.-III data list item No.
119 Battery current sensor calibration
is "Completed".
12.After the ignition switch is in LOCK (OFF)
position, disconnect the M.U.T.-III.
13.Install the battery
current sensor.
