Vehicles have many control units that need large amounts of
electricity. These units control their own system based on information
from diverse sensors. It is important to maintain a stable power supply
as these sensors give 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, check whether the
parasitic draw is not abnormal (Refer to vehicle parasitic current
inspection) |
It takes a few hours for a new battery sensor to detect the battery state correctly.
Perform the following process after replacing the battery sensor.
1. |
Turn the ignition switch ON/OFF. |
2. |
Leave the vehicle in parking mode for more than 4 hours. |
3. |
After 4 hours, check that the SOC (State of charge) of battery is displayed on GDS properly. |
|
For the vehicle equipped with a battery sensor, be careful
not to damage the battery sensor when the battery is replaced or
recharged.
• |
When replacing the battery, it should be the same (type,
capacity and brand) as originally installed on your vehicle. If a
battery of a different type is installed, the battery sensor may
recognize the battery to be abnormal. |
• |
When installing the ground cable on the negative post of
battery, tighten the clamp with specified torque of 3.9~5.9N.m
(0.4~0.6kgf.m, 3.0~4.4lb-ft). An excessive tightening torque can damage
the PCB internal circuit and the battery terminal. |
• |
When recharging the battery, ground the negative terminal of the booster battery to the vehicle body. |

Other information:
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be overheating.
If this happens, you should:
1.Pull off the road and stop as soon
as it is safe to do so.
2.Place the shift lever in P (Park) and
set the pa ...
Inspection
When using a wheel alignment tester to check the alignment of
the wheels, make sure that the vehicle is horizontal and the front
wheels are pointing straight ahead. Make sure that the suspension and
steering equipment are normal, the wheels are straight.
