sorry arbab...i thought it was the following:
posted by shak:
1. Sit in the driver's seat.
2. Turn the ignition to the On position, but do not start the engine up.
3. Immediately depress the accelerator fully and release fully 5 times quickly.
4. Wait for a few seconds and you will see the Check Engine light flash once, then start it will start to blink. All codes are comprised of 4 digits. The number of blinks corresponds to the fault code. For example, ON then pause, ON ON then pause, ON ON ON ON then pause, ON ON ON then off would be a 1243.
5. Each four digit code will be flashed sequentially. When the codes start to repeat, all stored codes have been displayed.
6. Turn the ignition off and check the codes with the table below. 1444 and 2444 means no problem and that is what you hope to find! Good luck

Asif I dunno if you have searched the forum but we have another thread regarding this, a previous one..

Does it differ from it by any chance ?

My BAD, I didnt researched actually, there was a question regarding the same, in another thread which i answered and thought lets create a new one with the same for everyone's reference. Anyhow, you can close / merge / move / delete the thread. Lets keep the city clean.

Thanks & Regards.

That means it was already unlocked

If i pressed button during "L-On" appearance for test (19.0), none of the tests from 3 to 15 will be showmen (i tried it). But immediately i pressed the button during "L-Off" appearance and its work.
For test (19.0) "L-Off" & "L-On" remain changing until the button has been pressed. and for both cases no need to enter any kind of codes
