The doors don't lock immediately but in about 30 to 60 seconds, they lock. I can have the door(s) opened or closed and the doors lock automatically even before I put the key in the ignition.
When the car is in drive, all the doors lock automatically also.

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.

Pic 1

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 doors were already in Mode B from the time I purchased the vehicle. I was just asking why do all the doors lock automatically when using remote control to open all the doors. This is even before placing key in the ignition.

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:

Will my vehicle close the doors automatically after I remove the key from the ignition? If I leave my key in the ignition, will the vehicle give me a warning beep? I know when I press the unlock button on my remote control, if I don't open a door within 30 seconds, the vehicle will close all the doors automatically.

Good morning,

When you remove the keys from the ignition, the doors will not lock automatically. You need to lock them with your remote. When you start the engine and start to move, the doors will lock. If you have an key for ignition, then yes, there should be a beep. If you have push button start, the remote will beep.

1. The remote does not work at all 2. The power lock button on the driver and passenger doors do nothing when pushed unless the key is turned on 3. Interior lights do not work at all 4. Clock built into dash does not light up Could it be a fuse? All of this appeared to occur at once within the last day. My wife tells me the temperature/compass reading in the rear-view mirror acted up in the last day or so but since then has cleared up (99 DegF here in the day)

Bought a tester and 10 amp fuse for "Gauge" is OK. Other ideas?

My wife took the van in so I don't have the code. Maybe I can get a shop to check again and tell me the actual code.

What's a good code reader for me to buy so I could check it myself? I'm fairly mechanical but never dealt too much past alternator replacement as far as electrical.

Codes in that particlar sequence indicates loose or defective fuel tank cap. An Actron CP 9575 excellent scan tool runs about $145 Auto Zone has good selection from $40 up. Check or replace cap clear codes by removing EFI 15 amp fuse in engine compartment box. See if they reset

Fuse was the problem and those lock and light problems disappeared. But then engine light came back on and now I have Code 1135. Air Fuel Ratio Sensor

I bought an Actron 9580. Has the code description built in along with likely fix.

I bought a Bosch Wideband A/F sensor (goes in exhaust pipe at front of engine just under the hood).
Sound like this is the fix?

Which fuse was the problem? I took mine to a store and told them I needed to replace whichever fuse was causing almost no interior lights (only left side of dash and a/c controls worked) and no locks unless you did each door manually. I really need to get this fixed, but I don't have much money to fix it.

BEVEYBS, it is probably the 10 amp dome fuse underneath the hood in the long fuse box beside the battery.

I had the same problem with my 2000 Sienna. The remote door fob unlock/lock would not work and the door lock/unlock switch inside the car on the driver s armrest would not work with the car turned off.
The blown fuse was under the hood in the fuse/relay box on the drivers side. The 10 amp fuse was labeled dome lights. There is a row of 3 spare fuses in that fuse box: a 10, 20 and 30 amp. I used the spare 10 amp fuse. Problem fixed.

I have the above noted car. For the last few weeks, the automatic locks will begin automatically switching on and off. This can occur while driving or while the car is turned off. I haven't studied it enough to test with cause and effect. It doesn't happen all of the time- but when it does, it is sure annoying. Any ideas on how I can remedy this problem?

Have you recently used a key to unlock one of them the is normally opened otherwise? IF so, unplug the micro door switch to the suspected door and see if the problem stops. Do this with each door until it stops, plugging the previous one back in.

Good chance a door switch is bad.
