5. CAN COMMUNICATION CONFIGURATION
The CAN topology is linked with CAN communication system, which consists of P-CAN and B-CAN.
The instrument cluster and BCM (Body Control Module) communicate through both P-CAN and B-CAN
at the same time, and the SKM (SMART Key Module) communicates with the instrument cluster and
BCM through B-CAN.
1) CAN Configurations (P-CAN/B-CAN)
Abbreviations Meaning Function
GCU Glow Control Unit Glow control unit
EPS Electronic Power Steering Unit Electrically driven power steering unit
BCM Body Control Module Body control module
SKM Smart Key Module Smart key module

1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITS
Disconnect the negative cable from the battery
in advance when working on electrical units. -
If a fuse is blown, replace it with a fuse which
has the correct amperage rating. If you use a
fuse with higher capacity than the
specification, the component can be
damaged or catch fire. -Do not drop or appy excessive impact to
sensors and relays. -

10 A 15 A
Make sure to turn "OFF" the ignition switch
and other lamp switches before disconnecting
or connecting the negative battery cable.
(Otherwise, semiconductor parts can be
damaged.)

Make sure a connector is connected
securely. Loose connection results in
malfunction. -
When disconnecting a connector equipped with
a lock, press it down to the direction in the below
figure. -
When checking voltage or continuity of the
connector terminal with a circuit tester, connect
the tester probe to the terminal at the harness
side. For a sealed type connector, connect the
probe to the terminal through the hole in the
rubber cap of the wiring. Take care not to
damage the insulation of the wires. Insert the
probe until it contacts the terminal completely. -
When inspecting the airbag system, make sure to use a diagnostic device, not a circuit tester.

2. CHECKING CABLES AND WIRES
Check for loose connection or rust.
Check terminals and wires for corrosion due to electrolyte leakage.
Check terminals and wires for open circuit.
Check the wire insulation and coat for damage, cracks or deterioration.
Check if the conductive parts of the terminals do not contact with vehicle body or other metal parts.
Check that the grounding part has continuity with mounting bolts and vehicle body.
Check that wires are properly routed.
Make sure that wires are securely fixed to avoid contact with sharp body parts and high-temperature
parts, such as the exhaust manifold and exhaust pipes.
The rotating parts, such as fan pulley and fan belt, perturbative parts and wiring should be secured
tightly at regular intervals.
Secure the wiring between the fixed parts, such as the vehicle body, and vibrating parts, such as the
engine, after slackening it slightly to prevent it from being damaged. -

ICM box
Interior fuse box
Fuse box in engine compartment
The fuse and relay boxes consist of three boxes: Integrated Control Module (ICM) box in which the
relays of rear wiper, rear fog lamp, mirror folding, ACC, IGN1 & 2, horn, tailgate, power outlet, shift lock
(A/T) are integrated, relay & fuse box in engine compartment and interior fuse box.
