System Overview: Signals

The table below summarizes the input signals to and output signals from the power seat module (PSM) (3/26). The signal types are divided into directly connected signals and CAN communication. The illustration below depicts the same information with Volvo component designations.

Input signals	Output signals
Directly connected:	Directly connected: (supply voltage unless otherwise specified)
Hall sensor (x 4, integrated in the seat motors)	Seat motors (6/16, 6/17, 6/18, 6/19)
Via CAN communication:	Via CAN communication:
Central electronic module (CEM) (4/56) Driver information module (DIM) (5/1) Driver door module (DDM) (3/126) Brake control module (BCM) (4/16)	Driver door module (DDM) (3/126) Passenger door module (PDM) (3/127) Central electronic module (CEM) (4/56) Driver information module (DIM) (5/1)
