Each location entry references the relevant diagram page for quick cross-referencing.

Layout of Controls

This section shows the physical layout of switches on the dashboard and on the overhead ledge, with a key-to-devices table that identifies each control by code, function and diagram page. Controls covered include the automatic transmission gear selector, work lamp lighting control, rear inter-wheel differential lock control, inter-axle differential lock, rear axle lift control, independent heating switch, headlamp level adjustment, roof hatch control, power take-off engagement controls, traction control cut-off (ASR), hill start aid, trailer brake holding control, vehicle emergency stop control, beacon warning lamps control, emergency call control, alarm panic button, hazard lights control, door locking control, body builder pre-arrangement controls, engine speed set-point control for difficult terrain, air suspension position access controls, axle load-shedding activation control, particulate filter regeneration activation control, work site mode activation control, tailgate pre-equipment control, AEBS system and lane departure warning. The overhead ledge layout covers microphone, reversing audible warning inhibition, alarm siren sound level reduction, door locking and ambience lighting controls.

Electrical Distribution

This is one of the most practically useful sections of the manual. It contains the complete fuse and relay tables for the EJB electrical distribution box, including fuse rating (in amps), folio reference, code, function and diagram page for every circuit. Separate tables are provided for the standard EJB box and the electrical distribution box used on gas vehicles. There are also tables of relays, diodes, and fuses located outside the distribution box, along with detailed connector pinout tables for Face A and Face B connectors – XCBB1, XCBB2, XCH1, XCH2, XCH3, XCR3, XCR4, XCR5, XCR7, XCR8, XCR11, XCR12, XCRI, XCRH, XCI1, XCI2, XCI3, XCIC1, XCIC2, XCIC3, XCIC4, XCIO1, XCIO2, XCIO3, XCIF1, XCIF2, XCIF3, XCIG1, XCIG2, XCIM1, XCIM2, XCIM3, XCIM4, XCIN1, XCIN2, XCIR1, XCIR2, XCIS1, XCIS2, XCIS3, XFB1, XFB2, XFD1, XFD2, XFD3, XFD4, XFF1, XFL1, XFL2, XFRC1, XFTP1 and XFTP2.

Why This Wiring Diagrams Manual Matters

Electrical faults on modern commercial trucks are among the most time-consuming and frustrating problems to diagnose without the right documentation. The Renault Trucks C and D Wide wiring diagrams manual gives you the complete electrical architecture of the vehicle – every circuit, every connector, every fuse, every relay and every earth point – in a single, coherent reference. Whether you are tracing an intermittent fault in the CAN bus network, replacing a sensor, repairing a damaged harness, adding body builder equipment, or performing a full electrical system diagnosis, this manual provides the accurate, vehicle-specific information you need to get the job done correctly the first time.

Using generic wiring diagrams or guesswork on a complex commercial vehicle electrical system leads to misdiagnosis, unnecessary parts replacement, and potentially costly damage to sensitive electronic control units. This manual eliminates that risk by showing you exactly how the system is configured for the C and D Wide, with connector pinouts that match the actual vehicle, fuse ratings that correspond to the real distribution box, and harness routings that reflect the physical layout of the truck.
