Do me a favor first, look on your option sticker that should be on the inside of the glove box door. I am looking for option YE9. You make mention of the vehicle having door modules, it looks like only the YE9 option has door modules. If you have YE9, it could be a very simple test. Locate your I/P fuse block, which I believe is under the left side end cap. There are two relays labeled lock and unlock. Swap the two relays. If now the rear doors unlock, and not lock, replace the relay that is now in the lock relay cavity.

Yes, I checked relay its works. Front door lock and unlock all works. Only rear unlock is not working.
I pulled out one connector from fuse box witch is you told me.
From connector to rear door is okay. But I check power from fuse box side connector when I push lock unlock.
Lock side I get power from it but I didnt get power from unlock side.
So I guess fuse block is something wrong.
I will check more.
Thank you for your time and help

You never stated if you had YE9, I can only guess you do if you are having rear door issues. Here is some schematics. Sorry about the size, it is the best reproduction I can do.

If you could ground the tan/black wire as shown at the BCM, it could control the relay as well. If there is no power on the tan and black wire, then there is a problem with the power to, or through the relay.

Thank you for your help. I changed fuse block and all relay. So now its all fixed. Basically I didnt get power to rear unlock from fuse block.
Thank you very much.
