”This document provides data, characteristics, instructions and methodology to perform repair interventions on the vehicle and its components.

Anyhow, this document is addressed to qualified and specialised personnel. Iveco commercial and assistance network personnel as well as all Iveco authorised points of assistance are specifically qualified and equipped to perform the repair interventions that are indicated in this document.

Before performing any intervention, check to have available the document relating to the vehicle model on which the intervention is being performed and also make sure that all accident prevention devices, such as, as a rough guide, goggles, helmet, gloves, shoes, as well as work tooling, lifting and transport tooling, etc., are available and efficient, and further make sure that the vehicle is put such a way that an intervention can be made in safety conditions.

Making interventions strictly observing the indications given here, as well as using specific tooling indicated, assures a correct repair intervention, execution timing observance and operators’ safety.

Each repair intervention must be finalised to the recovery of functionality, efficiency and safety conditions that are provided by Iveco. Each intervention, on the vehicle, that is finalised to a modification, alteration or else, which is not authorised by Iveco, involves the exclusion of any responsibility for Iveco, and, in particular, where the vehicle is covered by a guarantee, each such intervention involves an immediate lapse of the guarantee.

Responsibility for Iveco in repair intervention execution is excluded.

Iveco is available to provide all clarifications necessary to make interventions, as well as to provide indications in cases and situations not i ncluded in this document.

Data and information contained in this document could result not to be updated owing to modifications made by Iveco at any moment for technical or commercial r easons, or because of the need to adapt the vehicle to law requirements in different countries.

Inthecaseofadifferencebetweenwhatcontainedhereand what actually found on the vehicle, please contact Iveco network before making any intervention.”

The data contained in this publication might fail to reflect the latest changes which the Manufacturer may introduce at any time, for technical or sales purposes, or to meet the requirements of local legislation.

Copy, even partial, of text and drawings is forbidden.

NEW FEATURES DUE TO THE INTRODUCTION OF BODY COMPUTER 2 (BC2)

Functions moved from BC1, CM (now eliminated) and VCM:

- Engine cranking

- Some body builder sgnal

— Ext. Body Builder Cruise Control,

— Parking light,

— Parking brake.

Functions moved from CM to BC2:

- Window curtain,

- Red lght,

- Windscreen washer pump,

- Windscreen water low sensor,

- Vehicle standstill signal for BB.

Functions eliminated from the Multiplex:

- Rotating lights,

- Front window heater,

- Automatic snow chain.

Functions added to the Multiplex with BC2:

- External Light signal / Emergency light for BB

- K15 low for frame computer (the K15 with BC2 will be connected to Vbat instead of ground as BC1),

- Seat belt inserted sensor (not used at the moment),

- Fading white lights,

- New bed spot lights,

- Power preservation for production line and showroom, power management supplement shut off at very low battery,

- Programmable spare I/O,

- KW2000 on CAN.

Apart from these changes to the MUX system, the connectors are being standardised for the Stralis, Trakker and Eurocargo bodybuilders.

CAN LINES

Dialogue between the Multiplex system, vehicle systems, engine control unit, SCR system, radio and various setters is carried out by means of the CAN lines:

- BCB - Body Control Bus

- VDB - Vehicle Data Bus

- ECB - Engine Control Bus

- ICB - Instruments Cluster Bus

- IDB - Infotainment Data Bus

- FMB - Fuhrpark Management Bus

BCB (Body Control Bus) communication line

Allows communication between the different electronic systems on the vehicle. This line does not regard directly the units on the VDB line but the units that carry out different onboard services.
