Check the interior power distribution panel under the dashboard first, as most accessory and lighting faults originate there. Use a multimeter to confirm voltage and continuity before removing any protective element.
This vehicle uses multiple panels to distribute electrical load between cabin systems and engine components. The interior unit handles low-amperage circuits such as audio, dashboard indicators, and климат control, while the engine compartment module supports higher loads like cooling fans and ignition systems. Each slot is identified by a number and rated amperage, which must match the installed component.
Common issues include oxidized контакts, loose seating, and heat damage on frequently used circuits. Inspect terminals for discoloration or weak contact points, especially in circuits tied to lighting and auxiliary power outlets, as these often show early signs of wear.
Access typically requires removing a plastic cover secured by clips. Once opened, compare the slot numbering with a verified layout reference to identify each circuit path and avoid disconnecting active systems unintentionally.
NV200 Fuse Diagram Layout and Circuit Identification
Match each numbered slot on the electrical panel with its assigned circuit using a verified reference chart, focusing first on systems that have stopped functioning such as lighting, wipers, or accessory outlets.
The interior panel typically includes low-amperage elements ranging from 5A to 20A, controlling dashboard electronics, audio system, and cabin lighting. Slot numbers are printed next to each position, allowing quick identification when cross-referenced with a layout chart.
The engine compartment unit handles higher current loads, including cooling fans and ignition-related systems. These positions often use ratings above 30A and are paired with relays for switching control.
Reading layout and circuit paths
Identify each circuit by combining slot number, amperage rating, and wire color. Black wires often indicate switched power, while red wires usually supply constant voltage from the battery.
Grouped circuits are placed in adjacent positions, allowing faster diagnosis when multiple components fail at once, such as interior lighting or power outlets.
Check both sides of each protective element, as damage may not be visible from the top. Use a multimeter to confirm continuity rather than relying on visual inspection.
Common identification issues
Confusing relay positions with standard protective elements can lead to incorrect replacement, since relays manage switching rather than overload protection.
Installing a higher-rated component than specified can cause overheating and damage wiring insulation, especially in circuits with frequent load changes.
Interior and Engine Bay Fuse Panel Locations in NV200
Open the driver-side lower dashboard area to access the interior power distribution panel, which is mounted behind a small пластиковый cover near the steering column.
Remove the cover by pulling it outward; it is secured with clips and does not require tools. Inside, you will see a compact grid of protective elements assigned to cabin systems such as lighting, audio, and accessory power lines.
The engine compartment unit is positioned close to the battery and enclosed in a sealed housing. To access it:
- Press side latches on the cover
- Lift the крышка upward
- Locate larger amperage elements and relays inside
This under-hood unit manages high-load circuits, including cooling fans and ignition-related systems, so inspect it first when multiple major components stop working at the same time.
