By reading the "connector views" section of the diagram, you see exactly which cavity the wire lives in. You use a terminal release tool, extract the corroded pin, crimp a new one using the exact wire gauge (0.5mm² for signals, 2.5mm² for lights), and re-insert.

Modern vehicles rely on complex Controller Area Network (CAN) bus systems, but the W638 Vito sits in a transitional era. It utilizes a mix of traditional relay-based electronics and early electronic control modules. This hybrid nature means that while some systems are simple circuits, others rely on specific signal paths that are impossible to guess.
Understanding these codes allows you to look at a harness in your hands and match it to the schematic on your screen. Note: In complex looms, multiple colors may be used (e
⚠️ The W638 does not have a central "SAM" like modern Mercedes. It uses conventional fuses/relays plus an early engine control module (Motronic or EDC). Wiring is simpler but corrosion-prone.

Components are drawn as schematic symbols. Relays are crucial in the W638; the diagram will show the coil (the control side) and the switch (the load side). Mercedes diagrams often separate these visually, so you must follow the current track numbers to see how the relay activates the component.
