ID Code Entry Procedure
Activation of the registration mode:
The vehicle must have been unlocked by either the multi-remote controller or a transponder OK signal (TPOK)
from the vehicle's immobilizer.
Preparation: - Make sure all doors unlock.
- Make sure all multi-remote controllers to be registered are available.
- Make sure the batteries of all multi-remote controllers are in a good condition.
- Make sure all transmitting sources are out of the neighbourhood of the vehicle.
- Make sure the battery of the vehicle is in a good condition.b
Switch ignition-switch exactly six times from the ªLOCKº to the ªONº position within 10 seconds and return the
ignition switch to the ªLOCKº position (leaving the key in the ignition switch).b
After 2 seconds the registration mode is activated. The turn signal lamps will flash twice.
OKNG
Proceed with the registration mode.
NOTE
The registration mode is operated when:+The ignition-switch is turned to the ªONº position.
+4 multi remote controllers have been learned.
+No multi-remote controller or ignition switch input is received within 120 sec-
onds.
Registration mode
Press and hold the ªUNLOCKº button of the multi-remote controller.b
Press the ªLOCKº button 3 times.
Release the ªUNLOCKº button.cIf the multi-remote controller
code is registered correctly,
the turn signal lamp will flash
once.cNG

After registration of the requested No. of multi-remote controller(s),
confirm the ID-code(s) by switching the ignition switch to the ªONº
position.cIf the multi-remote controller
registration is performed
correctly, the turn signal lamp
will flash twice.
Take the ignition key out of the ignition switch and confirm the func-
tioning of all multi-remote controllers by locking and unlocking the

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
+ªSELF-DIAG [CURRENT]º
A current Self-diagnosis result is displayed on the CONSULT-II screen in real time. After the malfunc-
tion is repaired completely, no malfunction is detected on ªSELF-DIAG [CURRENT]º.
+ªSELF-DIAG [PAST]º
Return to the ªSELF-DIAG [CURRENT]º CONSULT-II screen
by pushing ªBACKº key of CONSULT-II and select ªSELF-
DIAG [CURRENT]º in ªSELECT DIAG MODEº. Touch
ªERASEº in ªSELF-DIAG [CURRENT]º mode.
NOTE:
If the memory of the malfunction in ªSELF-DIAG [PAST]º is
not erased, the User mode shows the system malfunction by
the operation of the warning lamp even if the malfunction is
repaired completely.
+ªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be erased.
Without CONSULT-II
After a malfunction is repaired, return Diagnosis mode to User mode by switching the ignition ªOFFº for at
least 1 second, then back ªONº. At that time, the self-diagnostic result is cleared.
How to Perform Trouble Diagnoses for Quick
and Accurate Repair
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
