Details and Technology
The parametric special module (PSM) provides an interface for accessing the vehicle electronic system.
Vehicle information — for example, about rotary light switch positions, direction indicators, open doors,
wiper switch positions, etc. — can be accessed and vehicle functions can be modified via ten inputs and
20 outputs.
Benefits and Arguments
• Caters for electrical modifications and retrofitting
Access to the vehicle electronic system is now only possible/permissible via one defined interface. This
improves protection of the vehicle’s basic functional integrity.
Remarks
Responsibility for programming the PSM lies with the relevant body manufacturer.
