Check the driver-side interior panel first and match each slot with its labeled circuit before replacing any protective insert. Use only the specified amperage rating marked on each component to avoid damage to wiring and control units.
This off-road SUV uses multiple distribution points, including a cabin-mounted panel and an engine compartment unit. Interior electronics, lighting, and accessory systems are routed through the cabin section, while high-load components such as cooling fans and ignition circuits are handled under the hood.
Each position is labeled with short identifiers like “ACC,” “IGN,” or “ECU,” indicating accessory power, ignition feed, and engine control circuits. When a system stops working, locate the matching label and inspect the internal metal strip for breaks or heat damage.
Keep spare blade-style inserts rated at 10A, 15A, 20A, and 30A. Repeated failures indicate wiring faults or failing components, so inspect the circuit path instead of replacing parts multiple times.

Locate the driver-side interior panel and verify each circuit position using the printed legend before removing any protective insert.
The cabin distribution unit contains blade-style components arranged in rows, with labeled circuits for lighting, audio system, power outlets, and control modules. Amperage values typically range from 10A to 30A, with lower ratings assigned to electronic controls and higher ratings supporting motors and auxiliary equipment.
The engine compartment unit sits near the battery and includes larger cartridge-style elements along with relays. Cooling fans, ignition circuits, and fuel system components are routed through this section, where higher current flow is required.
Each position is marked with identifiers such as ACC, IG, ECU, or HTR, linking the slot to a specific system. Inspect the internal metal strip for breaks or discoloration to confirm failure, and ensure all components are firmly seated to maintain stable current flow.
Use wiring color codes as an additional reference, with constant power lines often in white or blue and switched circuits in red or green. Secure all covers after inspection to protect connections from dust and moisture.
Interior Fuse Panel Layout with Circuit Labels and Amp Ratings
Check the driver-side interior panel and confirm each slot using the printed legend before removing any protective insert.
The panel is arranged in rows with labeled circuits tied to specific systems. Common identifiers include:
- ACC – accessory power outlets and audio system
- IG – ignition-switched circuits
- ECU – engine control unit supply
- GAUGE – instrument cluster and indicators
- WIPER – windshield wiper system
Each blade-style insert has a stamped amperage value that must match the original specification. Typical ratings include 10A for lighting and control modules, 15A for electronics, 20A for wipers, and up to 30A for higher-load interior components.
Ensure each insert is fully seated and inspect the internal metal strip for breaks or heat marks. Loose connections or incorrect ratings can lead to intermittent power loss across multiple interior systems.
