Hi Customer, Thank you for using JustAnswer.
What is the year, model and engine size
Do you have more than one transmitter?
You said when a passenger opens the door, The doors lock. Is this form the inside or the outside?
Sorry about that, the question timed out on me, and i could not reply. I have two other question. When the remote stops working. Did you try both remotes. As for the doors locking when someone opens the pass. door. I have an idea, but the information is not on the wiring diagram. On the passenger front door. If you unlock the door using the key does it unlock the other doors?
I have not forgotten you. I am at work right now. But i will be on line tonight around 8:00PM EST. I should have something for you by then.
I got it done early
If your power locks are still working. (you can unlock all the doors with the lock switch on the drivers door. Or with the key from drivers door.) I am going to tell you how to program your remotes. Using a jumper wire and the data link connector under the hood.
Code saving methodReceiver (ETACS module) can save maximum two codes from the transmitter.
Look under the hood by the battery. You will see a connector with a cover on it. See photo. This is what the connector looks like. You will need a piece of wire.(long enough to go from positive battery terminal to the connector.
(1)Connect one end of wire to the positive battery terminal. Connect the other end to the terminal "6" of DLC (Data Link Connector).
(2) Turn the ignition switch to "ON" position.
(3) If you only want to program one transmitter.Press the lock button of transmitter for over 3 seconds until the turn signal lamp turns off.
(4) If you want to program two transmitters.Press the lock button of one transmitter for 1 second until the turn signal lamp turns on, and then press the lock button of the other for over 1 second until the turn signal lamp turns off.
(5) Remove the jumper wire, and then the transmitter code is re-saved on the receiver.
(6) Check the operation of the keyless entry system.
Let me know what happens.
See picture for location. The connector has a cover over it.
First, do the power door locks work ? Can you lock and unlock all the doors from the drivers door or passengers door.
it sounds like wire should work. How long did you hold the lock button down for?
Can i git back to you in the morning. Its late and its been a long day. I think its probly going to be the ETACS module. But i wanted to verify it on a sorento i have in the shop.
Good night, Tony.
I will get back to you in the early afternoon.
Hi Customer, Sorry it took longer than i thought. Unfortunately you will need to replace the ETACS module. It is located in the center of the dash behind the radio. See photo.
A new ETACS module runs around $300.00. You might consider a used one. It is not common for the ETACS module to go bad, so a used one could save you money. Try http://www.car-part.com/ to find one used. I am uploading the procedures for replacing the ETACS. If you decide to buy used, give them the numbers off the old module.
