Check the panel cover first and match each slot number with its amperage rating to locate the faulty circuit without removing multiple links.
The interior power distribution unit is typically mounted behind a dashboard side cover and contains low to medium current blade-type elements rated from 5A to 30A. These positions supply systems such as lighting, infotainment, power outlets, and control modules.
Under the hood, a separate module handles higher load circuits including cooling fans, ignition supply, and braking system electronics. These positions use larger connectors and higher current ratings, often exceeding 40A for components with increased demand.
Use the printed layout on the cover or service manual to match slot numbers with assigned circuits and amperage values. A failed element usually shows a broken internal strip or burn marks, which can be confirmed with a multimeter set to continuity.
Repeated failure in the same position points to wiring damage or a malfunctioning component. Inspect harnesses, connectors, and grounding points before installing a replacement to avoid recurring issues.

Match each slot number with its amperage marking on the cover label, then use the layout chart to identify the exact circuit before removing any protective element.
The interior electrical unit includes low and mid-range current blade elements assigned to systems such as lighting, infotainment, dashboard cluster, and accessory sockets. Each position is numbered and grouped in rows for quick reference during inspection.
- 5A to 10A for control modules and sensors
- 15A for audio and interior power outlets
- 20A to 30A for windows and locking systems
The engine compartment distribution module handles higher load circuits, including cooling fans, ignition supply, and ABS components. These positions use larger cartridge-style elements with higher amperage ratings.
- Cooling fan circuits often rated above 30A
- Ignition supply connected through dedicated high-current slots
- Brake system electronics protected by separate high-load positions
A broken internal strip or visible burn marks indicate failure, while repeated issues in the same position suggest wiring damage or a faulty connected component that must be inspected before replacement.

Open the driver side door and remove the side dashboard cover to access the interior electrical unit positioned near the steering column.
This cabin-mounted unit sits behind a пластиковая trim panel secured with clips and can be removed by hand. Inside, rows of blade-type protective elements and relays are arranged in a compact layout, with numbering printed along the frame for quick identification.
Lift the hood and locate the main power distribution module near the battery, enclosed in a sealed plastic housing designed to protect high-current connections from moisture and dirt.
Press the locking tabs and remove the cover to access larger cartridge-style elements and relays assigned to systems such as cooling, ignition, and braking. Disconnect the battery before working in this area to reduce the risk of short circuits.
