3.Connect the battery cable without the battery current sensor to the negative battery terminal.
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. |
|
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. |
