Theory Of Operation

WARNING: This page is about a different car, the 2022 Chrysler Voyager and 2022 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.

Under normal vehicle stopped conditions, the Power Sliding Door System accepts an input (initiated by an operator activated switch) to open or close. Most of the inputs are toggle inputs and the resulting action of either open or close is the opposite of what was or is currently being executed; if a sliding door is closed or closing, it will open; if a sliding door is open or opening, it will close. The requirements of generating an sliding door request apply to the associated Power Sliding Door (PSD) module and the requirements for door movement apply to the associated Rear Door Module and Front Door Module, unless otherwise noted.

The associated PSD module has the responsibility of authorizing the operation requests. Door locked/unlocked is determined by the associated door lock signal from the associated Front Door Module. Door unlatched is determined by the associated door latch signal from the associated Front Door Module. The Front Door Module shall determine unlatched for the associated signal based on the Pawl Switch. The associated PSD shall remember (including during sleep mode) the last valid (not SNA) input states in order to detect a change. For any state other than described, the interior switch inputs shall be ignored.

If a hardware input maintains the same active value, such as button pressed, for more than 15 seconds, the input shall be disabled until the input changes value. The module that has the hardware input and transmits that value on the network (LIN or CAN) shall be responsible for disabling the input and transmitting the not pressed/not active value until the input is enabled. The Body Control Module (BCM) will perform the stuck disable for the Over Head Console (OHC) inputs. As a LIN switch bank, the OHC is exempted from the stuck disable requirement

If the left B-Pillar switch signal indicates transition to pressed and the operation request conditions are met, then a left sliding door operation will be performed. If the right B-Pillar switch signal, indicates transition to pressed and the operation request conditions are met, then a right sliding door operation will be performed.

If the left interior power sliding door handle switch indicates a transition to true and the operation request conditions are met, then a left sliding door operation is performed. If the right interior power sliding door handle switch indicates a transition to true and the operation request conditions are met, then a right sliding door operation is performed.

If the left exterior power sliding door handle switch indicates a transition to pressed, the operation request conditions are met, and the left sliding door is unlocked or unlatched, then a left sliding door operation is performed. If the right exterior power sliding door handle switch indicates transition to pressed, the operation request conditions are met, and the right sliding door is unlocked or unlatched, then a right sliding door operation is performed.

The Hands-Free Door Modules will not cause an inadvertent trigger operation when there is no input by the operator. The Hands-Free modules will be able to wake up the BCM via LIN upon a valid input. The BCM shall relay/share the Left Side Kick and Right Side Kick signals and status from LIN to CAN. The Hands-Free modules shall adjust the detection parameters based on the signals and status.

All of the following conditions associated with an operation request shall be met prior to initiating the associated sliding door operation. The PSD shall determine the correct conditions to operate the sliding door. Some of the following conditions, if not met, have an associated inhibit indicator that is reflected in the associated PSD status or signal. If an inhibit indicator is not specified, the associated PSD status or signal will indicate 'No message'.
