Parametric Special Module (PSM)
Details & Technology
The Parametric Special Module (PSM) is the gateway into the vehicle electronic system.
Vehicle information can be accessed and vehicle functions can be modified via 10 inputs and
20 outputs.
Outputs:
Vehicle status: Doors open / closed; locked / unlocked etc. Hand brake applied
Light control: Side lamps, brake light, turn signals, main-beam headlamps etc.
Engine CAN information: Vehicle speed, engine speed, gear selector position,
AC compressor etc.
Inputs:
Light functions: interior / exterior lights turn signals etc. wig-wag
Central locking: lock / unlock entire vehicle, load compartment
Alarm functions: hazard warning flasher, warning buzzer, horn
PSM signals can be combined to create logic combinations (AND, OR, NOR, XNOR etc.).
PSM signals can be processed internally in Timer, Counter and Hysteresis Blocks or Threshold
Switches to trigger specified Output signals or Input functions.
Benefits & Arguments
The Sprinter is networked with several bus systems and the PSM was developed to give body
builders access to individual types of CAN bus data. The PSM is the gateway to the CAN bus
and can be used to read vehicle information and control vehicle functions (e.g. the central
locking).
Remarks
The above listed signals are examples only. For a complete list of signals see the 'Sprinter
Body Builder Information Book' or contact Sprinter Sales Engineering.
The PSM program has to be uploaded to the PSM via the MB Star Diagnostic.
