    POWER SLIDING DOOR
    SYSTEM
    DESCRIPTION
    Some vehicles are equipped with a power opening
    and closing sliding door system (Fig. 1). Depending
    on how the vehicle is ordered it may be equipped
    with only a right side power door or right and left
    side power doors. This power sliding door system is a
    complex system consisting of many components.
    Some of these components are the door motor, latch
    assembly, sliding door control module, lower drive
    unit, flex drive assembly, wire harness and track,
    lower drive unit track and rack assembly, full open
    switch, B-pillar switch, overhead console switch, key
    fob switches (Fig. 2), pawl switch, ratchet switch and
    child lockout and handle switches.
    Each power side door has its own door control module,
    located in the center of the door behind the door
    trim panel.
    (Refer to 8 - ELECTRICAL/ELECTRONIC
    CONTROL MODULES/DOOR CONTROL
    MODULE - DESCRIPTION) The power side door
    motor is located in the front portion of the door, on
    the inner door panel sheet metal. The latch assembly
    is located in the rear of the power side door, near the
    body line. The lower drive unit is attached to the
    lower door hinge. The flex drive assembly connects
    the door motor to the lower drive unit. The wire harness
    and track and the lower drive unit track are visible
    with the door open in the lower door sill area.
    The power side door full open switch is located under
    the lower drive unit and is part of the hold open
    latch assembly. The pawl, ratchet, handle and child
    lockout switches are all located on the power side
    door latch assembly. The B-pillar switch, as it will be
    referred to, is an open and close command switch
    located on the vehicles interior body side B-pillar
    trim. The overhead console switch, is an open and
    close command switch located in the vehicle’s overhead
    console. More detailed information can be found
    on these components later in this section.
    Safety is of the utmost concern with the power
    sliding door system. Software technology has enabled
    the power sliding door control module 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 (while closing only). Battery voltage is
    supplied to the power sliding door system through a
    40 amp fuse, located in the Intelligent Power Module
    (IPM) assembly (Fig. 3). The child lockout switch prevents
    children from opening or actuating the power
    sliding door system when desired. 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,
    just like a standard manual sliding door.
    The power sliding door control module communicates
    on the J1850 PCI Data Bus Circuit. Therefore,
    the power sliding door control module can generate
    and store its own diagnostic trouble codes (DTC). A
    diagnostic scan tool, such as the DRB IIIt is used to
    read and diagnose these trouble codes. Refer to the
    Body Diagnostic Manual for a complete list of diagnostic
    routines.
    NOTE: It may be possible to generate Sliding Door
    Diagnostic Trouble Codes during normal power
    sliding door operation. Refer to the Body Diagnostic
    Manual for a complete list of diagnostic routines.
    For additional information, (Refer to 8 - ELECTRICAL/
    POWER DOORS - OPERATION). For a complete
    power sliding door system wiring schematic,
    refer to Wiring Diagrams. For power sliding door system
    operation instructions, refer to the vehicle owner
    manual.
    WARNING: BE CERTAIN TO READ ALL WARNINGS
    AND CAUTIONS IN POWER SLIDING DOOR OPERATION
    BEFORE ATTEMPTING ANY SERVICE OF
    POWER SLIDING DOOR SYSTEM OR COMPONENTS.
    OPERATION
    With the push of a power sliding door open/close
    command switch (key fob, overhead console or B-pillar
    mounted) a signal is sent out to the Body Control
    Module (BCM). The BCM then sends a signal out on
    the PCI Data Bus circuit (J1850) to the power sliding
    door module. The power sliding door module then
    signals the power sliding door latch to release the
    door to the unlatched and movable position. The
    motor then starts an open cycle.
    During the door open cycle, if the power sliding
    door module detects sufficient resistance to door
    travel, such as an obstruction in the door’s path, the
    power sliding door module will immediately stop door
    movement and reverse door travel to the full open or
    closed position. The ability for the power sliding door
    module to detect resistance to door travel is accomplished
    by hall effect sensors and the door motor
    speed.
    The power sliding door control module 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 Diagnostic Scan Tool, such as the DRB IIIt, or with
    a complete cycle of the door, using any one of the
    command switches. Refer to Standard Procedures in
    this section for detailed instructions.

    I replaced the motors in both my doors a couple weekends ago. They worked fine for a day. Now they just pop open and stop. Do the latches need replaced? or does the module need reset? Can I reset it somehow?

    Everyone with power doors that work intermittently try this:

    Open the hood, then the fuse center. Remove the fuse labeled IOD. This is for the BCM. Wait a few minutes then plug it back in. I did this and while either side door just popped open at first, after manually opening then closing them with the door button, they seem to work every time (open and close). This was done on a van that sat over night without beibng started in cold weather (32) so I think it discounts the cold weather theory. I think it is something to do with the stupid BCM software or something. Let me know if this hel;ps anybody else!!!

    I purchased mine from wholesalemopar.com for around $250 each plus shipping. Total cost was about $550 as I remember.

    The door are self learning about how much force to use to open it. So if it just pop opens and goes nowhere else, you need to reset the BCM so that it does the self learning again so it can adjust with your use.

    sliding doors

    I have a different door problem with my 2001 TC. The drivers side sliding works fine if the drivers door is open. If you try to close the sliding door with the drivers door shut, it will close and immediately reopen. All other sliders work fine.

    It makes no difference which button you use the results are always the same.

    Any ideas?

    I tried this, but it didn't work for me. Went to dealer in Chattanooga this morning and asked them to reset the codes. They said this didn't work either. Dealer says I need new latches. Also claimed my driver's side door motor was bad, but I have just replaced both door motors two weeks ago. I noted to the technician that my doors slide much easier than the brand new showroom model!! So I guess I'll go for the new latches and hope this gets the door problem solved. There is a thread on here somewhere showing replacing the door latches solved one guy's problems.
