Driver Seat Module
The driver seat module (DSM) controls the adjustable pedals, only when the vehicle is equipped with the programmable/recall memory option (excluding Executive Series models).
NOTE:
DSM diagnostics are compatible with the Worldwide Diagnostic System (WDS). The DSM incorporates multiple functions into one module and offers diagnostics to easily locate and repair concerns affecting the subsystems that it controls.
The DSM constantly monitors the systems under its control and reports a concern in the form of diagnostic trouble codes (DTCs). A DTC can be retrieved with the WDS or equivalent through the communications link.
