System Overview: Signals
The table below summarizes the input signals to and output signals from the driver door module (DDM) and passenger door module (PDM). The signal types are divided into directly connected signals, LIN and CAN communication. The illustration below (Fig 1) displays the same information with the Volvo component designations.
