2005 Hyundai sonata is nowhere mentioned in the bulletin, how can we use this bulletin for my car?

In top right corner It is mentioned 1999 sonata.. And in the first table in repair procedure 1999-2004 sonata's are mentioned. So, how would this procedure applied to 2005 model?

Hello, I'm Andrew. Let me do some research and see what I can find about helping diagnose this issue.
Customer: replied 6 months ago.
Hi Andrew, I will be awaiting your response.
Expert:  Andrew Martin replied 6 months ago.
Alright, first off, lets check fuse 17 in the inside fuse box to the left lower of the steering wheel. If that one is good, we're gonna wanna check the A/T fuse (#6) in the under hood fuse box. I have attached pictures to help.
Customer: replied 6 months ago.
Yeah both are good.
Expert:  Andrew Martin replied 6 months ago.
Ok, you need to check the A/T control relay. Its under the center console but you can reach it from the driver side by the gas pedal. Just remove that trim piece and you can get to it. It should have a diagram on it with pin numbers next to the pins. You'll need to power up the coil and give it ground and see if the relay clicks over. Either that or you can just replace it. I've attached a picture to show you where it is.

Previously when i took my car to a repair shop, one mechanic checked and said that was good. Anything else could be wrong?
Expert:  Andrew Martin replied 6 months ago.
It's either that or the pcm
Customer: replied 6 months ago.
Where is PCM located? How it looks like? How to check whether or not it is working..?
Expert:  Andrew Martin replied 6 months ago.
PCM is located right in front of the AT relay in the same picture I sent you. You'll want to check connector # ***** 2, the second one from the front in the picture. With the car running, check for voltage at pin 10 of that connector. I've attached a picture to help. You'll have to check it with the connector connected, its a green wire. Just probe it from the back.
