Door Switch Module (DSM)

The DSM receives power from the DDM. The DDM receives LIN inputs sent from the DSM for window motor actuation.

The DSM includes the following switches:

• Low current driver window lift switch (DWLS)
• Low current passenger window lift switch (PWLS)
• Low current rear left window lift switch (RLWLS)
• Low current rear right window lift switch (RRWLS)
• Low current rear window lock-out switch (RWLOS)

The DSM contains an internal LIN transceiver and uses this to communicate switch requests to the DDM.

The window switches incorporated to the DSM have four positions; two positions for press-to-open and two positions for pull-to-close. Both switch positions have two detents; one for manual open/close and one for express open/close. Each of these positions and detents are LIN bussed to the DDM for window operation.

Each rear door has its own window lift switch. These rear switches have two positions; one position for push-to-open and one position for pull-to-close. When either rear switch is pressed, it will apply battery level voltage and ground to the appropriate power window motor. The window motor will automatically stop when the full open or closed position is reached. Neither rear switch is capable of express window operation.

The DSM backlighting is tied to the panel lamps driver of the interior lamps system. When the headlamp switch is turned ON, the DSMs Light Emitting Diodes (LED) illuminate.
