Locate the power distribution panels in both the cabin and engine compartment, then match each slot number with the printed circuit chart before attempting any replacement. Use a test light or multimeter to confirm power flow instead of relying only on visual inspection.
The interior panel typically handles low-current systems such as lighting, radio, and accessory circuits, while the engine compartment unit manages high-load components like starter motor, cooling fans, and braking systems. Amperage ratings vary from 10A to 60A depending on circuit demand, and each slot is labeled to prevent incorrect installation.
Check relay positions alongside protective elements, as many systems rely on switching components rather than direct current flow. Relays for fuel delivery, ignition, and HVAC are grouped near high-current slots, making identification faster when tracing faults.
Inspect contacts and wiring connections for heat damage, corrosion, or looseness. Clean terminals if oxidation is present and ensure replacements match original ratings to avoid circuit overload or component failure.

Match each slot number in the power distribution panel with the printed circuit chart inside the cover, then verify voltage using a multimeter before replacing any protective element. Focus on high-current lines such as starter, ABS, and cooling fans, as they rely on larger amperage ratings and dedicated relays.
Identify relay positions рядом with corresponding circuits to trace switching functions for ignition, fuel delivery, and HVAC systems. Check for discoloration, melted plastic, or loose terminals, as these indicate overheating or poor contact; replace damaged components with identical ratings to maintain stable operation across all connected systems.

Check the interior panel by opening the driver-side door and removing the trim cover at the lower dashboard edge; the unit sits behind this panel and contains low-current circuits for lighting, audio, and accessory systems.
Locate the engine compartment power distribution center next to the battery on the driver side; it is housed in a black plastic enclosure with a removable lid secured by clips. Thick cables from the battery feed directly into this unit.
The cabin-mounted unit uses smaller amperage components, typically ranging from 10A to 30A, and is arranged in rows with numbered slots molded into the plastic base. The cover usually includes a printed circuit chart for quick identification.
In the engine area, the main distribution center handles high-load systems such as starter motor, cooling fans, braking module, and ignition control. Larger amperage ratings, often between 30A and 60A, are used here, along with multiple relays positioned рядом with corresponding circuits.
Inspect both locations for secure mounting and clean connections, ensuring covers are properly sealed to prevent moisture entry and corrosion that can disrupt electrical flow.
