SECURITY AND LOCKS
CODE WORD INPUT PROCEDURE
W 6 U 9 1 4 W 3 4
Note
• A code word is composed of eight digits from 1— 9 and is part of the Immobilizer unit from manufacturer.
Each unit has its own code word. To obtain the code word, you need to have the Immobilizer serial
number, then ask importer/distributor.
• The process for inputting the code word to the PCM is done by cycling the ignition key and counting the
number of flashes of the security light. The catch of number from security light flashing comes with the
timing of that cycling of the key.
1. Wait for 5 minutes until security light flashes slowly. (300 ms ON, 300 ms OFF -> 1.2 s ON, 1.2 s OFF)
2. Input the code word as the example shown bellow.

(1) Turn ignition switch to ON during security light OFF and count three illumination cycles. As the light goes
o u ta fte rth e t h i r d illumination, turn key to LOCK.
(2) Within 30 second of going to LOCK, turn ignition switch to ON during security light OFF and count one
illumination cycles. As the light goes out after the first illumination, turn key to LOCK.
(3) Repeat step (2) for rest of six digits.
3. When code word is registered correctly in the PCM. The security light stops flashing and illuminates.
4. As soon as the security light stops flashing and illuminates, the following immobilizer system reprogram
procedure should be started.
Note
• If the code word is not input correctly, the security light goes out after all eight digits are input. In this case,
perform the “Code Word Input Error Recovery Procedure”.
Examples of Incorrect Input of Code Word
Note
• The security light must flash one or more times between the figures of the code word.
• If the code word is input incorrectly, the security light goes out. Turn the ignition switch to ON then back to
LOCK five times (except PCM replacement) or six times (PCM replacement) and repeat the procedure to
input the all eight figures for the code word.
• When an error occurs during the reprogram procedures except when both the immobilizer unit and PCM
are replaced, repeat the procedure from step 1. If you still can not reprogram, confirm how many keys can
start the engine. Then, perform the key replacement or addition reprogram procedure according to the
valid key number.
• The security light flashes ten or more times while the ignition switch is at ON position.
