Why does my car's doors lock after using the remote to open all the doors

Hi,

The automatic door lock in this vehicle has different modes of operation. I suspect you want it to lock the doors when you shift from park to a drive gear and then unlock when you park and place the shifter back to park. The is mode B.

Here are the directions for programming it to do that. The attached pic correlates with these directions.

Initialization Procedure

Perform the following procedure to initialize the ADL function to Mode B.

1. Move the shift lever into the "P" position and close all doors.

2. Turn the ignition switch to the "ON" position.

3. Within 10 seconds after the ignition switch is turned to the "ON" position, push and hold the rear side (unlock position) of the door lock switch for 5 seconds.

4. All doors will automatically lock and unlock when you release the power door lock switch.

This indicates that the ADL function is set to Mode B. If all doors do not lock and unlock, the time the switch was held may have been too short or too long. Perform the procedure over again starting from step 1.

Let me know if that helps.

The only thing I can think of then is if there is a short to the ADL prompting it to actuate. What I would suggest is to scan the CAN bus system on the vehicle. CAN stands for computer area network. It should show if there is a break down of communication or a fault specific to any one module in the vehicle.

Here is a quick video showing how and why to do this:
