Communication Bus Architecture

The manual opens with a full breakdown of the vehicle’s communication networks. It documents the LIN BUS architecture and the CAN BUS architecture across Euro III, Euro V, Euro VI and Euro VI Step-E with ECM 4.0. Device keys list every ECU, sensor and control unit on each bus segment, including the instrument cluster, engine ECM, EBS, transmission control, door modules, alarm, tachograph and telematics gateway. This section is essential for diagnosing communication faults, identifying bus termination points and understanding how each module talks to the others.

Shared Functions

The shared functions chapter groups the vehicle’s major electrical systems into clear, self-contained schematics. Each shared function includes its own key to devices with component codes, descriptions and grid locations. Systems covered include:

• Distribution and management of electrical power (with and without ADR)
• Euro III, Euro V, Euro VI and Euro VI Step-E anti-pollution systems
• Air production management
• Mechanical suspension
• Windscreen wiper and washer
• Electric rear-view mirrors
• Display and instrumentation
• Braking management (front, rear, controlled axle and trailer)
• Engine management (11-litre and 13-litre, all emissions standards)
• Driveline and differential lock management
• Automated manual transmission management
• Retarder
• Tachograph
• Windows and sunroof
• Interior and exterior lighting
• Locking and unlocking of doors
• Alarm and immobiliser
• Safety and driving assistance
• Air conditioning

These schematics show the main equipotentials of each system, the communication buses involved and the equipment that affects the function. They serve as the top-level overview before diving into the detailed wiring diagrams.

• Safety management – immobiliser, door management, alarm, camera monitoring, airbag and alcotest
• Lighting and signalling – headlamps, rear lights, side parking lights, roof-mounted parking lights, horn
• Washing and wiping of windows
• Driving assist – front radar and side radars
• Life on board – cab compartment lighting, independent heating, air conditioning, heated seats, windscreen de-icing, sunroof, entertainment module and accessories
• Vehicle maintenance – cab tilt
• Trailer connections – rigid and tractor sockets
• Body builder system management – pre-equipment ECU, main ECU, central chassis ECU, electrical distribution box, supplementary lighting and BBIOM

Each diagram includes wire colours, pin numbers, connector references and component codes, allowing precise tracing of circuits from the battery to the load and back to earth.

Equipment Locations

This section provides a full summary of equipment locations with page references. It covers the distribution box, main information display (short and long dashboard), tachograph, electronic management of 11-litre and 13-litre engines across all emissions standards, fuel management, urea supply, vehicle management, power-assisted steering, energy production, air production, gearbox management, retarder, braking management, suspension, tyre management, differential lock, driveline management, vehicle maintenance connectors, power take-off, door management, safety systems, bodywork pre-equipment, life on board systems, driving assist, video surveillance, interior and exterior lighting, horn, washing and wiping, and earth points. This makes it fast to locate a component on the vehicle before beginning work.

Layout of Controls

The layout of switches on the dashboard and overhead ledge is documented with clear illustrations and component codes. This helps identify the function of every switch, its location and its associated diagram page.

Electrical Distribution

This chapter contains the complete fuse and relay tables for the electrical distribution box, including fuse ratings, circuit descriptions and diagram page references. It also covers fuses and relays outside the distribution box, the face A and face B connector pinouts of the distribution box, and the power supplies available inside the cab and on the chassis. This is the go-to reference for any electrical fault diagnosis.
