Why it helps
Trace an electrical fault from fault code to the exact pin and wire colour without a separate wiring tool.
The Electronics card lists every electronic system on the vehicle, grouped as Engine, Brakes, Steering and Suspension, Exterior/Interior, Fuses and Relays, Locations, Warning Lights and Electronic Procedures.
Open a system to see its components, wiring diagram, CAN-Bus overview, locations and step-by-step fault code diagnosis. Open a component for its diagnosis, wiring, ECU pin and connector table, location, related parts and component information. You can trace an electrical fault from the fault code to the exact pin and wire colour without a separate wiring tool.
