Hyundai Santa Fe: Fuses And Relays / Relay Box (Passenger Compartment). Description and operation
ICU (Integrated Central Control Unit)
ICU (Integrated Central Control Unit) is an integrated model of smart junction
block and central gateway.
It performs the function of conventional "Smart junction block" and the function
of communication medium of "Central Gateway".
Battery Monitoring System
When the risk of battery discharge is detected due to excessive current consumption
from using electrical device such as black box while the engine is OFF.
The system warns the customer of battery discharge through the warning message
on the cluster.
The battery sensor detects the excessive current consumption of the battery
and the Integrated Central control Unit (ICU) records the battery discharge
history.
When the battery discharge is detected, the message warning the customer is
displayed on the cluster and the battery is charged using the alternator when
the engine is driven.
The recorded history can be checked via optional diagnostic tool function: "Check
the battery discharge warning history".
Checking the battery discharge warning history
– |
This function allows checking the history of excessive battery consumption
of the parked vehicle.
|
– |
It is possible to check the running distance and SOC when the battery
consumption was excessive and the current SOC information.
|
Using diagnostic tool, the "Check the battery discharge warning history" function
of ICU is implemented.

Description
Continuous Variable Valve Timing (CVVT) system advances or retards the valve
timing of the intake and exhaust valve in accordance with the ECM control signal
which is calculated by the engine speed and load.
By controlling CVVT, the valve over-lap or under-lap occurs, which makes better
fuel economy and reduces exhaust gases (NOx, HC) and improves engine performance
through reduction of pumping loss, internal EGR effect, improvement of combustion
stability, improvement of volumetric efficiency, and increase of expansion work...
