Schemi elettrici interattivi a colori ad alta risoluzione con pinout connettori ECU e logica dei circuiti per ogni modello.
Perché i nostri schemi sono diversi
I PDF generici fanno perdere ore. I nostri schemi interattivi sono creati per la ricerca guasti reale.
Schemi interattivi a colori
Naviga in circuiti complessi con percorsi codificati per colore. Clicca su un componente per saltare al relativo circuito.
Pinout ECU e connettori
Ogni connettore mappato con numeri pin, colori fili e valori attesi di tensione o resistenza.
Diagrammi rete CAN Bus
Viste topologiche complete delle reti CAN-H/CAN-L, moduli gateway e percorsi di comunicazione.
Valori di test circuito
Valori di riferimento per tensione e resistenza su ogni punto di test per eliminare incertezze.
Cablaggio sensori ADAS
Schemi dedicati per radar, telecamere, LiDAR e sensori a ultrasuoni con note per la calibrazione.
Esportazione per l'officina
Esporta ogni schema in un PDF pulito da stampare o portare sul veicolo senza necessità di un secondo dispositivo.

Wiring Diagram FAQs
Yes. All wiring diagrams from Haynes Pro and Mitchell1 are delivered in full colour, with each wire colour matching its physical colour to make tracing circuits intuitive and fast.
Yes. Component locator diagrams show the exact physical location on the vehicle with reference photographs, so you know exactly where to access the connector before you lift the bonnet.
We provide wiring diagrams for the vast majority of European and global vehicles from 1990 to present. Coverage includes all major makes: BMW, VW, Ford, Toyota, Mercedes, Renault, Peugeot, Honda, and 140+ more.
Yes. High-voltage circuit diagrams for BEV and hybrid systems are included, with clear safety warnings and isolation procedures for working on live HV components.
Yes. Hover over any ECU connector in the diagram to see expected voltage, signal type and ground values for every pin — speeding up multimeter-based diagnostics significantly.
