Hyundai Sonata: Battery Sensor. Description and Operation
Description
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)
