Locate the main electrical distribution unit under the hood near the battery before checking any circuit fault. This vehicle uses separate protection blocks for engine and interior systems, each containing labeled slots tied to specific components such as lighting, ignition, and control modules.
Each protective element has a defined amperage rating, typically from 5A to 30A, and is color-coded for quick identification. Always install a replacement with the same rating to prevent overheating or damage to wiring and connected systems. A visible break in the metal strip indicates failure.
The interior unit, positioned on the driver side near the dashboard, manages lower load circuits such as radio, interior lights, and switches. Using the layout reference helps trace faults accurately and avoids removing functioning components during inspection.

Check the legend printed on the panel cover first to match each circuit slot with its assigned system before removing any protective element. This avoids disconnecting power from critical components like ignition control or fuel delivery.
Locate the interior electrical panel near the driver side lower dash and identify numbered positions. Typical assignments include lighting circuits, radio supply, and dashboard instruments. Use a plastic puller tool to extract each unit safely and inspect the metal strip for breaks or burn marks.
For under-hood distribution, inspect the larger power center positioned close to the battery. It contains higher amperage links for cooling fans, ABS module, and charging system. Replace only with identical ratings to prevent wiring damage.
- 10A slots usually serve interior lighting and small electronics
- 15A–20A protect outlets and audio systems
- 30A and above support motors and heating elements

Open the hood and inspect the area directly next to the battery on the driver side to find the main power distribution unit secured with a plastic cover; release the side clips to access high-amperage circuits for cooling fans, starter relay, and charging system, then cross-check each slot using the printed legend inside the lid.
Check the lower dashboard on the driver side by kneeling near the pedals and removing the small trim panel to reach the interior circuit block; this section handles low to mid current lines such as cabin lighting, radio supply, and instrument cluster, and each position is numbered for quick identification, allowing targeted inspection without disconnecting unrelated systems.
