Replace sliding door safety switch

Could be Child safety lock help prevent the rear doors from being opened accidentally. The child safety lock levers are located on the edge of the rear doors.

DESCRIPTION
Each power sliding door is equipped with a Power Sliding Door Control Module (1) (PSDM). The PSDM is mounted directly to the inboard side of the power sliding door drive assembly (2) with two retaining screws. The drive assembly is mounted to the body near the bottom of the sliding door in the track cavity with the use of five retaining nuts. The wire harness and chain link track and the power sliding door drive assembly are visible with the door open in the lower door sill area.
Software technology has enabled the PSDM to detect resistance to door travel. This allows the power sliding door to stop and reverse direction any time an obstruction is felt or any of the command switches are operated. Battery voltage is supplied to the power sliding door system through a 40 amp fuse, located in the Totally Integrated Power Module (TIPM) assembly. The power sliding door lockout switch located in the front overhead console prevents opening or actuation of the power sliding door system when activated. In the unlikely event that the power sliding door system develops a fault, the power sliding door can still be operated manually from the interior or exterior door handle similar to a standard manual sliding door.
NOTE: It may be possible to generate Sliding Door Diagnostic Trouble Codes during normal power sliding door operation. Refer to the appropriate power sliding door diagnostic information for a complete list of diagnostic routines.
OPERATION Battery voltage is supplied to the power sliding door system through a 40 amp fuse, located in the Totally Integrated Power Module (TIPM) assembly. With the push of a power sliding door open/close command switch (key fob, overhead console or B-pillar mounted) a signal is received by the Power Sliding Door Control Module (PSDM). The PSDM receives this signal via the Controller Area Network (CAN) Data Bus circuit. The PSDM then signals the power sliding door cinching latch to release the door to the unlatched and movable position. The power sliding door drive assembly motor then starts an open cycle.
The overhead power sliding door switch is mounted in the front overhead console of the vehicle. The switch has resistors in parallel of 1.76K ohms, 3.17K ohms and 15K ohms. When pressed, the switch will have a nominal resistance of 1.76K ohms for the right sliding door button, 3.76K ohms for the left sliding door button and when not pressed, the switch will have a nominal resistance of 15K ohms.
The status of the overhead power sliding door switches is continually monitored by the circuitry within the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). The instrument cluster receives input messages from the overhead power sliding door switches over a hardwired connection. Whenever the instrument cluster receives an input from the overhead power sliding door switches it sends a function command signal to the selected PSDM. This message from the cluster to the PSDM is delivered via the Controller Area Network (CAN) data bus.
The B-pillar switch is located on the lower B-pillar trim panel and allows the rear occupants to power open or close the sliding doors. The B-pillar switch is an R-Mux switch that has a resistance of 3.6K ohms and 16K ohms depending on switch position. When pressed the B-pillar switch will have a nominal resistance of 3.9K.
The B-pillar switches are hardwired to the Totally Integrated Power Module (TIPM). The PSDM receives the message for operation status via the Controller Area Network (CAN) data bus. If all the necessary conditions are met the PSDM will then perform the requested operation. The B-pillar switch lockout feature must be disabled and the sliding door must be unlocked in order for the B-pillar switch to function.
The FOBIK switch sends a signal to the Wireless Ignition Node (WIN). The PSDM receives the message from the WIN for operation status via the Controller Area Network (CAN) data bus. If all the necessary conditions are met the PSDM will then perform the requested operation. The vehicles theft alarm must be disabled and the sliding door must be unlocked in order for the FOBIK switch to function.
When one of the PSDMs receives a command signal it checks the following:

1. PRNDL Status
2. Vehicle Speed Status
3. Ignition Status
4. Vehicle Theft Alarm Armed/Disarmed Status
5. Sliding Door Latch Status
6. Sliding Door Full Open Status
7. Ambient Temperature
8. Door Lock Status
9. Sliding Door B-Pillar Switch Lockout Status
10. Sliding Door Window Up/Down Status

If the appropriate conditions exist the PSDM will send a command signal to the selected Rear Door Control Module (RDCM) so the sliding door can be latched/unlatched as needed. This command signal is sent via the CAN data bus. Once the PSDM senses the latch function it will power the motor on the power sliding door drive assembly to open/close the sliding door as requested by the overhead power sliding door switches.
During the door cycle, if the PSDM detects sufficient resistance to door travel, such as an obstruction in the door's path, it will immediately stop door movement and reverse door travel to the full open or closed position. The ability for the PSDM to detect resistance to door travel is accomplished by hall effect sensors detecting the door motor speed.
The PSDM has the ability to learn. Anytime a door is opened or closed using the power sliding door system the module learns from its cycle. If a replacement power sliding door component is installed or a door adjustment is made, the module must re-learn the effort required to open or close the door. A learn cycle can be performed with a complete cycle of the door, using any one of the command switches or with the use of a scan tool. (Refer to 08 - Electrical/Power Sliding Door - Standard Procedure) for detailed instructions.
The power sliding door system is designed with a number of system inhibitors. These inhibitors are necessary for safety and/or feasibility of the power sliding door system. The power sliding door system inhibitors are:

1. The power sliding door must be in the full open or closed position in order for the power sliding door system to start a normal cycle. If the door is not in this position (based on the input from the switches integral to the cinching latch assembly) the PSDM will only perform a power open cycle.
2. The transmission must be in park or neutral in order for the power sliding door system to start a cycle.
3. The front overhead console lockout switch must be in the "UNLOCKED" position in order for the power sliding door systems B-pillar switches to function.
4. If multiple obstacles are detected during the same power open or close cycle the power sliding door may go into full manual mode.
5. If severe Diagnostic Trouble Codes (DTC) are stored in the PSDM the power sliding door may go into full manual mode.
6. Due to the high pressure created in the passenger compartment with the blower motor on high, the power sliding door may not complete a power close cycle unless a window is cracked, allowing the pressure to escape. This situation will only be experienced on some vehicles, or vehicles with brand new side door weather seals installed.

The hard wired circuits for the power sliding door switches may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the electronic controls and communication between other modules and devices that provide some features of the power sliding door system. The most reliable, efficient, and accurate means to diagnose the power sliding door switches or the electronic controls and communication related to the power sliding door system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

POWER SLIDING DOOR SYSTEM WARNINGS

WARNING: Always disconnect the negative battery cable before attempting any power sliding door system service.
WARNING: Extreme care must be taken to prevent objects from entering the doors path once the door reaches the cinch motor contact (approximately 1 inch before fully closed). Never place objects in the power sliding door when cinching closed. The obstacle detection function is inoperative during the cinch phase and damage to the vehicle, power sliding door system or components and/or personal injury may occur.
WARNING: Never attempt to enter or exit the vehicle while the power sliding door is in motion. You could damage the power sliding door system or components and/or cause personal injury.
WARNING: Never attempt to drive away with the power sliding door in motion. You could damage the power sliding door system or components and/or cause personal injury.

disengage the saftey Anon, I believe it is done on the overhead console or if you mean the child prevention lock, it is a small switch by the doors latching assembly. Links below give instruction.

How To Install Replace Power Sliding Door Lock Actuator Chrysler Town and...

Do a reset on the door system, by pulling the door fuse. I don't have location, possibly drivers side fuse box.

Try this... it fixed my problem whereby the 2005 Toyota Sienna passenger sliding door would sometimes open and sometimes not, yet I could hear the motor trying to open/close it. It cost me 20 minutes and 10 drops of oil, not $1200.

First, get the door open. It took me two weeks of constant trying, but it finally opened.

Next, remove the plastic covering of the inside door handle this way: locate the two screws on the forward edge of the sliding door near the child-safety switch: (the switch is a small lever near the door latch, on the forward edge of the door) loosen and remove the two phillips screws, one above the child-safety latch, and one below.

Remove the plastic cover to expose the gears for the door open/close mechanism.

There's a bunch of intricate plastic and metal parts in there, all coated with white grease. I used some 3-n-1 oil to lubricate everything in there thoroughly, In my case, there was one part that was a little void of grease, hence it "stuck" occasionally.

Test the system. If it's Okay, replace the plastic cover, and re-install the screws.

Now my Toyota Sienna 2005 door never fails to open or close.

Show me how to take the safety child lock off switch also I need a picture of this location on the door

Hi,

Thanks for using FixYa!

The most probable cause for this problem is blown fuse. Check for the door fuse under the dashboard. You should be able to see a fuse diagram found on the fuse box cover. I hope this helps.

Thanks and have a nice day.

Has the door been serviced as in clean and lubricated tranck?A lot of power is not put to the opening or clsin mechanism for safety reasons

Do you know anything about automotive electronics ?
All courtesy lamps are controlled by the generic electronic module (GEM).
The four contacts are not switches , the part you want to replace is the door ajar switch . The door ajar switch is inside the door part of the lock actuator . Those contacts just allow circuit continuity when the door is closed , when you open the door continuity is broken or open . The GEM now know the door is open an will now turn on the dome lights . The door ajar switches stick , try spraying WD-40 into the door latch ,open an closing the latch . If this doesn't fix the problem you will need to take the inside door trim panel off and replace the ajar switch .
