All doors lock automatically when the vehicle speed reaches 15 MPH (24 km/h).
? All doors unlock automatically when the ignition is placed in the OFF position.
The automatic unlock function can be deactivated or activated. To deactivate or activate the automatic door unlock system, perform the following procedure: 1. Close all doors.
2. Place the ignition switch in the ON position.
Within 20 seconds of performing Step 2, push and hold the power door lock switch to the position (UNLOCK) for more
than 5 seconds.
4. When activated, the hazard indicator will flash twice. When deactivated, the hazard indicator will flash once.
5. The ignition switch must be placed in the OFF and ON position again between each setting change.
When the automatic door unlock system is deactivated, the doors do not unlock when the ignition switch is placed in the OFF position. To unlock the door manually, use the inside lock knob or the power door lock switch (driver's or front passenger's side). NOTE: The automatic door unlock function can be changed using the Vehicle Settings in the vehicle information
Taking your vehicle to a qualified repair shop instead of mess with thing's you have no clue about ,is what you should have done . Replacing BCM'S - needs to be programmed .
If the body control module (BCM) is replaced, the following procedures must be performed in the following order:
BCM reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
Theft learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent. A new BCM will learn the Passlock™ information automatically but the powertrain control module (PCM) must still learn the theft information from the BCM.
Plus the bcm has nothing to do with the power window's DDM -the driver door module controls the window .
Programmable Automatic Door Locks
The automatic door lock feature can be programmed to control the door lock system. The automatic door lock feature is factory programmed to have all doors lock and unlock. For detailed instructions on programming the automatic door locks, refer to Vehicle Personalization in Personalization.
When the automatic door lock feature is programmed to control the door lock system, the driver door module (DDM), passenger door module (PDM) and body control module (BCM) will lock the vehicle doors if the following inputs are true:
• Ignition 1 input is active.
• All door jamb switch inputs are inactive.
• Cargo door or liftgate/liftglass ajar inputs are inactive.
• Transmission is shifted out of park.
This automatic door lock function will only occur once per ignition cycle unless, a door jamb switch input changes state to active and back to inactive. Then the DDM, PDM and BCM will lock all doors again.
Once the automatic door lock feature has locked the doors, the BCM will then unlock all the doors when the transmission is shifted into park.
Before replace these componets hooking up a factory scan tool an checking data input's an DTC'S - diagnostic trouble codes .
You do not specify, whether you ability to lock the doors is inside the vehicle, or with a remote. Are you the only one in the vehicle most times it is used? Is there another "rocker" switch, on another door to see if it will lock a door. In most cases (not all) it is a simple matter of replacing the switch. Automatic lock, & automatic windows, operate on the technical term of a 'momentary' contact switch. As long as it is being pressed, it is sending current, into the lock or window to make it operate the device in the direction you want. If the other side of the switch fails.......nothing. I think this is where you should start. Napa, is a good source for "look alike" replacement switches.
if you use the keyless entry to unlock the vehicle & don't open a door within 30 secs.the vehicle will automatically lock & the alarm will reset,if you unlock it with the key this shouldn't happen.....cheers.
That sound is going to be your door lock motors wearing out. I would suggest getting them replaced pretty quickly as they will soon stop locking altogether. It's not cheap, but it isn't horribly expensive either.
Go to your fuse panel (under your dash). Remove the fuse marked "door". It may be named something else, perhaps "locks".
Once you find and remove the fuse, give it a try at speed. Hopefully the fuse only supplies door lock power and not your windows. More than likely this will render your door locks completely manual.
However, there was a recall on this vehicle for this problem.
NHTSA Campaign ID Number: 92V135000 Component: Structure: Door Assembly: Latches And Locks Manufacturer: Toyota Motor Co., Ltd. Year: 1989 Make: Toyota Year of Recall: 1992 Type of Report: Vehicle Potential Number of Units Affected: 554,910 Defect Summary: The electronic control unit (ECU) for the power door lock system can fail, causing the contacts to "weld", and resulting in door lock solenoid damage, with failure of the door to lock or unlock, even under manual operation. Consequence Summary: If the door fails to open after ECU failure, vehicle occupants would have increased difficulty exiting the vehicle in an emergency. Corrective Summary: Install an additional sub-circuit relay control to prevent malfunction of original relays in the ECU.
So the thing to do is contact your local Toyota dealer and have the recall performed.
I have had this problem once before. I solved it by resetting the "automatic locks" setting on the overhead console...first turned this off and then turned it back on a day later and the locks worked again fine.
