Check the electrical distribution panels first when a system stops working, as most faults are linked to a blown protective element or a failed relay. Use the panel cover chart to match each slot with its assigned circuit before removing anything.
This vehicle uses multiple power distribution units, including one inside the cabin and another under the hood. The interior unit handles systems such as lighting, infotainment, and seat controls, while the engine compartment module manages higher load circuits like cooling fans and ignition supply. Each slot has a fixed amperage rating that must be matched exactly.
Inspect both panel locations during diagnostics, since several systems rely on components split across different sections. For example, climate control and power accessories may involve both interior and engine-side elements.
Typical signs of failure include intermittent operation, partial system shutdown, or visible heat damage on terminals. Replace faulty elements with identical ratings and ensure tight контакts to avoid repeated issues.
Keeping a printed circuit layout inside the vehicle allows quick identification of slots and relays during roadside checks and reduces time spent tracing wiring manually.

Match each numbered slot with its circuit using the panel cover chart before removing any component, as similar amperage ratings can lead to confusion and incorrect replacement.
The interior power distribution unit contains low and mid-range current elements that protect systems such as audio, interior lighting, seat adjustment, and control modules. Ratings typically range from 5A to 30A, with clear numbering inside the panel.
The engine compartment unit handles higher load circuits, including cooling fans, ignition supply, and ABS. These positions often use larger cartridge-style elements designed for sustained current flow under load.
- Interior lighting and dashboard systems
- Infotainment and navigation controls
- Power seats and window regulators
- Engine control and fuel delivery circuits
Relays are located within the same distribution units or in adjacent sections and manage switching for systems like the starter, air conditioning compressor, and radiator fans. Identify each relay by its position code before testing or replacing.
- Turn off ignition and disconnect battery negative terminal
- Access the required panel based on the failed system
- Locate the correct slot using the printed chart
- Inspect the internal metal strip for breaks
- Swap relay with identical unit if needed
Check for overheating marks, corrosion, or loose контакts, as these issues can interrupt current flow without visible damage to the protective element. Ensure all components are firmly seated after inspection.
Exact locations of interior and engine bay fuse panels with access instructions
Open the driver-side lower dash cover to reach the interior power panel, as it is mounted behind a removable trim section near the steering column. Pull the cover outward to release clips and expose the electrical distribution unit.
Use steady pressure when removing the panel to avoid breaking plastic fasteners, and check the inner side for the slot layout chart. A flashlight helps identify numbering and circuit labels in tight spaces.
Engine compartment panel access
The under-hood distribution unit is positioned near the battery on one side of the engine bay. Release the locking tabs on the protective lid and lift it straight up to access high-current elements and relays. Ensure the battery negative terminal is disconnected before handling any components to prevent short circuits.
Inspect surrounding wiring and keep all covers secured after service, as proper sealing protects the internal components from moisture and debris.
