SPECIFCATIONS
ENGINE COMPARTMENT JUNCTION UNIT (CVM)
Electromechanical control unit including fuses (maxi and mini), relays and circuits for interconnecting front wiring and radiator prewiring.
These wires are connected to the control unit via fixed joints. A tray beneath the protectivecover houses any further connectors/relays/fuses
A fastening is provided on the lower cover for sealed fuse carrier connectors (maxi and mini type).
1 - Engine compartment junction unit (CVM)
2 - System protection maxifuse
3 - Maxi type relay
4 - Micro type relay
5 - System protection mini fuse
6 - Connection cable between battery control unit (CBA) and engine bay control unit (CVM)
7 - Battery control unit (CBA)
The maxi fuses grouped on the battery control unit (CBA) and engine bay control unit (CVM) are connected directly to the battery positive terminal and protect the main power supply lines.
The engine bay control unit (CVM) is described below
In the more comprehensive version, the engine bay control unit protects the electrical equipment by means of the following fuses:

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 = NPL
The 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.

CARATTERISTICHE
CENTRALINA VANO MOTORE
La versione GTA è dotata di una nuova centralina elettromeccanica comprendente fusibili e teleruttori (di tipo micro), collocata nel vano motore accanto alla batteria.
Il coperchio di protezione garantisce la tenuta stagna richiesta per connettori, teleruttori e fusibili.
Accanto alla centralina è collocata una staffa che alloggia altri teleruttori (di tipo MAXI), anch'essi protetti da apposita copertura.
1 - Coperchio di protezione
2 - Centralina vano motore
3 - Teleruttori tipo maxi (esterni alla centralina)
4 - Teleruttori tipo micro
5 - Fusibili protezione impianto
