MAJOR CHANGES
For vehicles with engines of Euro 4 and the electric and electronic equipment are subject to important changes.
To manage the increased complexity? features Euro-4, which requires the system to control the engine more hardware and software resources ? was introduced the control unit VCM (Vehicle Computer Module) which is the reallocation of the functions of vehicle, up
Euro 3 carried out by the control unit controllomotore EDC, then the greater flexibility? development for the functions in the vehicle. In this electronic control unit is also integrated immobilizer function.
New Body Controller (IBC3) unlike the IBC2 distributes direct and positive under lock and key, protected by external fuses (replaceable) or internal (recoverable).
In part the case, we have the unit MET (Electronic Module to the Chassis) that controls the power devices on the chassis.This unit can? be compared to the control units, the FFC and RFC of the Stralis.
For the net positive ? the state introduced a strap positive battery and the fuse box additional (75000) in close proximity? of the batteries.
The SCR system (Selective Catalytic Reduction) - Denox 2 ? present for the entire Range of Medium/Heavy vehicles with Euro 4 the Dosage Form Urea (UDS) is positioned on the frame.
The engine control unit ECM (Engine Control Module) replaces EDC 7, even if physically ? similar to it.
The new Cluster ? always monochrome of the functions in pi? compared to the previous one.
The introduction of new units and the change of existing ones involve changes on the structure of the vehicular system. Instead of a single line CAN VDB (for vehicles with Euro 3), we also have the system EasyMux made from small-Body Controller (IBC3) and MET that communicate via the CAN line BCB.
