How to read it

Retarder system belongs to the gearbox & driveline group of the Scania specification. The variant tells you what the vehicle was ordered with — Without means the option was not fitted at the factory . The specification is fixed at production: if the vehicle was modified afterwards (a PTO added, an axle converted), the FPC list still shows the original order, while the SOPS parameters show the current configuration of each control unit. Scania SOPS Editor decodes the full specification of a SOPS file with these descriptions — including the codes themselves, which are not published here.
