BODY COMPUTER NODE E04 (NBC)

The Body Computer Node (NBC) controls many functions microelectronically and is interconnected to the facia electromechanical control unit (CPL). They are located in the area beneath the facia and make up a single unit known as the facia node (NPL).

1 - Body computer (NBC)2 - Facia control unit (CPL)NBC+CPL = NPLThe electronic part and the electromechanical part both act as interconnections with the system and contain fixed connectors for connection to front, rear and facia wiring.The fuses and relays are fitted to the electromechanical part while the electronic part contains a fixed EOBD connector Diagnosis/programming of the NCM, NFR, NCR and CAB are carried out using a K line via this connector and also diagnosis/programming of components with a B-CAN interface.
