Check the interior power distribution panel on the driver side lower dash first, as most cabin-related malfunctions originate there. Lighting circuits, infotainment system, and accessory outlets are grouped with protection ratings typically ranging from 10A to 20A.
Open the hood and locate the main underhood distribution unit near the battery. This section manages high-load systems such as cooling fans, ignition control, and charging circuits, using higher-rated protection components between 30A and 60A.
Use the printed layout inside the cover to match each slot with its assigned function. If the cover is missing, identify connections by wire color coding and connector positions. Frequent failure in the same circuit or visible heat damage indicates deeper wiring or component faults rather than a simple overload.

Use the panel cover chart to match each slot with its assigned circuit before replacing any protective element, as incorrect placement can disable multiple systems at once. Interior circuits such as power windows, radio, and dashboard controls are grouped in the cabin distribution panel, while engine-related loads are separated to reduce interference and simplify fault tracing.
Trace each circuit path from the battery through the distribution center to the end component using wire colors and connector positions; this helps identify breaks, overload points, or corrosion. Consistent voltage readings across terminals indicate stable connections, while drops under load often point to damaged wiring or failing relays located рядом с силовым модулем под капотом.

Check the left side of the dashboard near the driver footwell to access the interior power distribution panel; remove the plastic cover to reveal labeled slots for cabin systems. This section handles low and mid-range loads such as lighting, infotainment, and accessory ports.
- Mounted behind a snap-on or screw-fixed trim panel
- Positioned close to steering column lower area
- Includes identification chart on inner cover surface
Open the hood and inspect the area adjacent to the battery to locate the engine compartment distribution unit, enclosed in a sealed housing for protection against heat and moisture. This module supports high-current circuits linked to ignition, cooling fans, and charging system.
- Placed near battery positive terminal connection
- Covered with a tight-sealing lid with clip locks
- Contains larger amperage protection elements and relays
