Theory Of Operation

The Left Rear Door Module (DMRL) is responsible for the operation of all latch requests. The door locked/unlocked status is determined in the DMRL by the door lock signal. The DMRL stores the last valid input for the latch status (including sleep mode), in order to detect a change. For any state other than described below, the interior switch inputs are ignored.

The power operation requests are applied as follows:

1. If the power sliding door is fully closed or closing, then the next movement would be to open.
2. If the power sliding door is fully open or opening, releasing (not cinching) excluded, then the next movement would be to close. A power operation request that occurs during a latch releasing (in the 'Latch releasing state' or 'Release sector home state') is arranged to be recognized after the release operation has completed (handle requests excluded).
3. If the power sliding door is not fully closed or fully open or closing or opening, and the door position is known, then the movement would be to open.
4. If the power sliding door is not fully closed or fully open or closing or opening, and the door position is not known, then there is no operation and the inhibit message indicating manual operation is displayed.
5. If the sliding door latch could not reach the closed (primary) position and has timed out in the open (secondary) position, no operation requests shall be recognized until the door is fully closed by manual operation.
