SEAT MODULES

NOTE: Right installation is shown, left installation is similar.

1. DSM with seat memory
2. PSM with seat memory

The seat modules are located under the driver and passenger seats, rely upon a number of inputs to control various outputs. Operation of the driver seat is controlled by the DSM. Operation of the passenger seat is controlled by the PSM.

Depending on vehicle configuration, the DSM controls the following functions:

• Driver seat adjustment
• Driver seat lumbar function
• Driver seat memory store and recall (if equipped).

Depending on vehicle configuration, the PSM controls the following functions:

• Passenger seat adjustment
• Passenger seat lumbar function
• Passenger seat memory store and recall (if equipped).

The DSM and the PSM have a fused permanent power supply from the Passenger Junction Box (PJB) and the Rear Junction Box. The driver/passenger seat switchpack sends operating requests to the PSM and DSM through Local Interconnect Network (LIN) connection.

The DSM and the PSM are connected to the High Speed (HS) Controller Area Network (CAN) body systems bus. The system allows the DSM to monitor the position of the door mirrors when storing and recalling memory settings. The signals are provided by the DDM and the PDM. The signals for the memory store and recall functions are received from the BCM/ GWM through the HS CAN body systems bus. The HS CAN body systems bus connection also allows the DSM and the PSM to transmit memory information. The confirmation chimes and display messages on the IPC message center are activated.
