Check the exact position and labeling of each circuit protector before any repair, since mismatched amperage or incorrect placement may lead to wiring damage or failure of onboard systems. The vehicle uses multiple protection panels: one under the hood near the battery and another inside the cabin, typically located beneath the dashboard on the driver’s side.
The engine compartment unit contains high-capacity elements responsible for critical components such as the starter motor, cooling fans, and ABS module. These slots are usually marked with values ranging from 30A to 120A. Pay close attention to relay placement in this section, as relays for ignition and fuel delivery are often grouped рядом with these high-load circuits.
Inside the cabin, the secondary panel manages lower-amperage circuits, including lighting, audio system, climate control, and power accessories. Ratings here commonly vary between 10A and 20A. A clear understanding of the labeling scheme–typically printed on the panel cover or in the owner’s manual–helps quickly identify the correct slot for each function.
Use only identical amperage replacements and verify each slot against the official layout reference for this specific SUV generation. Even a slight mismatch can cause intermittent electrical issues or disable safety features such as airbags or stability control.

Locate the power distribution panel under the hood near the battery and use the lid legend to match circuit numbers with functions such as ignition coils, fuel pump, or cooling fans; for interior circuits, check the panel behind the lower dash on the driver’s side and align slot positions with labels like ACC, audio system, or power outlets to isolate faults quickly. If a component fails, pull the corresponding insert with plastic tweezers, inspect the metal strip for a break, and replace it with the same amperage rating marked on top (e.g., 10A, 15A, 20A) to avoid wiring damage or overheating.
For accurate identification, note that engine-bay slots are grouped by high-load systems and often use larger cartridge-style elements, while cabin sections contain mini blade types for lighting, infotainment, and auxiliary electronics; cross-check numbering sequences since they run left-to-right and top-to-bottom, which helps avoid pulling the wrong piece. When diagnosing intermittent issues, lightly wiggle the seated insert to detect loose контакты, then verify continuity with a multimeter set to resistance mode; zero or near-zero reading confirms a good link, while infinite resistance indicates a break. Keep spare inserts in multiple ratings in the glove compartment, and never substitute with a higher value, as this can lead to melted insulation and damaged control modules.

Pull off the small trim panel on the left side of the dashboard, directly facing the driver’s knee area, to reach the interior electrical block; it sits flush behind a snap-on cover just above the footwell and slightly forward of the door hinge line. The access notch is on the lower edge–use fingers to pry it open without tools. Behind this cover, the main cabin protection panel is mounted vertically, while an additional relay cluster is fixed deeper toward the firewall, partially hidden by bundled wiring. For better reach, slide the seat back fully and angle the steering wheel upward.
Lift the hood and locate the main power distribution unit on the passenger side, positioned between the battery and the air filter housing, close to the inner fender. The housing is a rectangular black case secured with two side latches; press them inward and raise the lid to expose internal components. A secondary control module is installed further back near the firewall, slightly offset toward the centerline and partly covered by harnesses. Identification markings for each circuit are molded into the underside of the крышка, allowing quick verification during inspection or replacement.
