Self Study Program 265 – Vehicle electrics in Polo Model Year 2002

VAG SSP 265. The range of electrical systems in new vehicles is expanding increasingly as a result of the ever more effective safety systems and enhanced convenience systems. The vehicle electrics in the Polo Model Year 2002 have been reorganised with the aim of retaining a clear arrangement within the comprehensive onboard power supply.

A major role in this connection is played by a onboard power supply control unit. It monitors the capacity utilisation of the onboard power supply and performs functions which, until now, were executed by separate relays and control units. Moreover, the databus diagnostic interface, which permits data transfer between different CAN databus systems, is also integrated in the onboard power supply control unit.
