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.

The ESCL (Electric Steering Column
Lock) is a device which locks the
steering handle with an electrical
signal.

9. ESCL CONTROL
ESCL lock/unlock is not performed at ESCL virgin mode.
The SKM does not carry out the ESCL LOCK control if the engine is running with IGN ON or the
vehicle speed is 3 km/h or higher.
All the ESCL functions including START/STOP switch is disabled during anti-scanning flag bit set. -
-
-
If the smart key is pressed with power off, the electric steering motor performs the steering column
unlock. In some cases, power transition is carried out to ACC or IGN ON.
If the power transition and start is not possible after retry to LOCK or UNLOCK operation, the power
transition and start is not still possible after automatic retry and the warning lamp comes on. -
-
1) ESCL LOCK Control
When the ESCL is unlocked and the followings are met at normal condition:
If the driver door is open or closed with ignition key OFF, the electric steering motor performs the
steering column lock.
If the theft deterrent mode is activated by the LOCK signal from the passive or REKES key when
The ESCL LOCK is performed after 60 seconds since the ignition key is turned to B+ from
-
-
-
2) ESCL UNLOCL Control
When the ESCL is locked and the followings are met at normal condition:

Ignition status change*
If above conditions are met again, the SKM re-verifies the transponder and sends the verification
status for another 10 sec.
When the ignition status is changed by a smart key verification while the transponder verification is
processed, the SKM sends the signal for [transponder verification fail], and sends the smart key
verification status for 10 sec. -
-
(6) Transmission position warning
When the gear selector lever is in a position other than P or N with IGN ON and engine started, the
SKM sends the [gear position warning] signal to the instrument cluster through the BCAN for up to 10
sec. until the operating conditions are deactivated.
Transmission position warning deactivation
When re-attempting to start with IGN1 ON and transmission in P or N -
(7) ESCL JAM warning
The SKM transmits the warning active command to the BCAN through the BCAN signals such as ESCL
NOT LOCKED warning signal or ESCL JAM warning signal within 10 seconds or until the active
command deactivation conditions will be met, if jam is occurred when the electric steering motor is
locked/unlocked.
Failure Detecting Conditions
When the UNLOCK retry occurs after ESCL LOCK command, the ESCL LOCK is performed.
- The UNLOCK retry is possible up to 2 times automatically. If the UNLOCK retry occurs 3 times
in succession, the ESCL NOT LOCKED warning is triggered.
- Reactivates when the ESCL LOCK conditions are met.
When the LOCK retry occurs after ESCL LOCK command, the command will be overridden without
retry.
- After the command is overridden, the ESCL NOT LOCKED warning is triggered.
- Reactivates when the LOCK conditions are met by pressing the START/STOP switch after
ESCL UNLOCK.
When the LOCK retry occurs after ESCL UNLOCK command, the ESCL UNLOCK is performed.
- The LOCK retry is possible up to 2 times automatically. If the LOCK retry occurs 3 times in
succession, the ESCL JAM warning is triggered.
- Reactivates when the ESCL UNLOCK conditions are met by pressing the START/STOP
switch.
When the UNLOCK retry occurs after ESCL UNLOCK command, the command will be overridden
without retry.
- After the command is overridden, the ESCL JAM warning is triggered.
- Reactivates when the UNLOCK conditions are met by pressing the START/STOP switch after
ESCL LOCK. 1.

EPS)
CAN scan(This message goes off when all the CAN signal inputs
are normal)
ESCLLCD display shows this message when ESCL (Electric
Steering Column Lock) system is defective. There is
no specific ESCL warning light on the instrument
cluster.
This problem could be temporary. Turn the ignition off
and then on again to check if this message will be
disappeared.
This message helps the driver to predict the driving
direction since the tire alignment is displayed on the
instrument cluster.
The images on the left show that the tires are
aligned to the left. When the tires are aligned to the
right, the image is symmetrical vertically.
Tire alignment is displayed between level 0 and
level 5 depending on the alignment degree when
the ignition switch is turned to "ON" position from
"OFF" position with the shift lever in "P" or "N"
position. While the images up to level 2 comes on
for 5 seconds, the images from level 3 stay on.
These messages are not displayed when the EPS
check message is displayed. -
