Hyundai Kona: ISG (Idle Stop & Go) System / Battery Sensor Description and operation
Vehicles have many control units that use more electricity. These units control
their own system based on information from diverse sensors. It is important
to have a stable power supply as there diverse sensors giving a variety of information.
Battery sensor is mounted on battery (-) terminal. It transmits battery voltage,
current, temperature information to ECM. ECM controls generating voltage by
duty cycle based on these signals.
| • |
When battery sensor signal fault occurs, inspect the vehicle
parasitic draw in advance after inspecting the sensor because
the sensor will behave abnormally when the parasitic draw is
more than 100mA. (Refer to vehicle parasitic current inspection)
|
|
|
Perform the following process after replace the battery sensor.
| • |
Ignition switch ON/OFF.
|
| • |
Park the vehicle about 4 hours.
|
| • |
After 4 hours later, check the SOC (State of charge) of battery
using GDS.
|
|
| • |
For the vehicle equipped with a battery sensor, be careful not
to damage the battery sensor when the battery is replaced or
recharged.
|
| 1) |
When replacing the battery, it should be same one (type, capacity
and brand) that is originally installed on your vehicle. If
a battery of a different type is replaced, the battery sensor
may recognize the battery to be abnormal.
|
| 2) |
When installing the ground cable on the negative post of battery,
tighten the clamp with specified torque of 4.0-6.0 N.m (0.4-0.6
kgf.m, 3.0-4.4 lb-ft). An excessive tightening torque can damage
the PCB internal circuit.
|
| 3) |
When recharging the battery, ground the negative terminal of
the booster battery to the vehicle body.
