Inspection |
1. |
Disconnect the negative (-) battery terminal.
|
2. |
Pull out the relay from the engine compartment relay box.
|
Power Relay (Type A)
|
Check for continuity between the terminals.
1. |
There should be continuity between the No.30 and No.87 terminals when
power and ground are connected to the No.85 and No.86 terminals.
|
2. |
There should be no continuity between the No.30 and No.87 terminals
when power is disconnected.

1. |
There should be continuity between the No.30 and No.87 terminals when
power and ground are connected to the No.85 and No.86 terminals.
|
2. |
There should be no continuity between the No.30 and No.87 terminals
when power is disconnected.
|
Replacement of PCB Block
1. |
Disconnect the negative (-) battery terminal.
|
2. |
Push 4 hooks in the engine room relay box out to the arrow direction
and put up the PCB block (A).
|
3. |
Disconnect the connector and remove the the PCB block (A).
|
Fuse
1. |
Be sure there is no play in the fuse holders, and that the fuses are
held securely.
|
2. |
Are the fuse capacities for each circuit correct?
|
3. |
Are there any blown fuses?
If a fuse is to be replaced, be sure to use a new fuse of the same capacity.
Always determine why the fuse blew first and completely eliminate the
problem before installing a new fuse.

Dscription 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.

Fuse Inspection |
1. |
Check that the fuse holders are loosely held and that the fuses are
securely fixed by the holders.
|
2. |
Check that each fuse circuit has the exact fuse capacity.
|
3. |
Check the fuses for any damage.
|
Diagnosis with Diagnostic Tool
1. |
In the body electrical system, failure can be quickly diagnosed by using
the vehicle diagnostic system (diagnostic tool).
The diagnostic system(diagnostic tool) provides the following information.
|
2. |
If diagnose the vehicle by diagnostic tool, select "DTC Analysis" and
"Vehicle".
|
3. |
If check current status, select the "Data Analysis" and "Car model".
|
4. |
Select the 'ICU' to search the current state of the input/output data.
|
Removal |
1. |
Disconnect the negative (-) battery terminal.
|
2. |
Remove the crash pad lower panel.
(Refer to Body - "Crash Pad Lower Panel")
|
3. |
Disconnect the connectors (A) from the fuse side of the ICU.
|
4. |
Remove the ICU (A) after loosening the mounting nuts.
|
5. |
Disconnect the connectors from the back side of the ICU.
|
Installation |
1. |
Install the ICU.
|
2. |
Install the crash pad lower panel.
|
3. |
Connect the negative (-) battery terminal.
|
4. |
Check that all system operates normally.
|
ICM (Integrated Circuit Module) Relay Box. Description and operation
Description |
The ICM relay is united with (rear wiper relay, seat heater relay(front/rear),
head lamp washer relay and rear A/C relay) which installed inside the lower
crash pad.
