Check the interior panel under the dashboard on the driver side first, as most electrical faults like non-working lights, radio failure, or dead power outlets are tied to this location. Use the amperage rating printed on each slot and match it with the vehicle manual or cover label to avoid installing the wrong component, which can lead to wiring damage or repeated failures.
The engine compartment power distribution unit sits near the battery and handles high-load circuits such as cooling fans, ABS, and ignition systems. Always disconnect the battery before accessing this area to prevent short circuits. Pay attention to relay positions, as they often control switching for major systems and may be mistaken for standard protective elements.
Each slot is assigned to a specific circuit, including headlights, fuel pump, ECU, and HVAC controls. Identify the exact slot number and its function before removal, then inspect the metal strip inside for breaks or burn marks. A visual check combined with a multimeter test gives more reliable results than guessing based on symptoms alone.

Locate the cabin-mounted electrical panel beneath the steering column and use the cover label to match each slot number with its assigned circuit. Verify amperage values such as 10A for interior lighting and 15A for accessory sockets before removing any component to avoid misplacement.
The engine bay distribution unit near the battery contains high-load protection elements and switching modules. Circuits here typically include radiator fan control, ignition coils, and ABS system feeds, with ratings ranging from 30A to 80A.
Each position inside the panel corresponds to a dedicated system, including ECU power supply, fuel pump relay, and climate control. Check the printed legend carefully and compare it with wiring references when diagnosing power loss.
Burned or damaged inserts often show a broken metal strip or darkened plastic housing. Replace only with identical amperage units, as higher ratings can cause overheating in the wiring harness and connectors.
Relay locations are usually grouped next to high-current slots and control switching for headlights, starter motor, and cooling fans. Swap relays with identical part numbers during testing to confirm faults without installing new parts.
Interior circuits commonly include:
- Audio system and infotainment control
- Dashboard illumination
- Power windows and mirrors
- Central locking system
Engine compartment circuits commonly include ignition, charging system links, and main power distribution lines. Use a multimeter to check continuity and voltage at each slot rather than relying only on visual inspection.

Check the driver-side lower dashboard area behind a small plastic cover to access the interior electrical panel. Open the cover by pulling from the notch near the bottom edge, then use the printed legend on the reverse side to identify each slot tied to cabin systems like lighting, audio, and power accessories.
The engine compartment power unit is positioned next to the battery on the left side of the engine bay. It is secured with a clipped lid that must be pressed and lifted to reveal high-current protection elements and relays. Circuits in this area support systems such as cooling fans, ignition supply, and braking electronics. Ensure the ignition is off and the battery terminal is disconnected before opening to avoid accidental short circuits or component damage.
Key access points include:
- Driver footwell left side behind trim panel
- Engine bay near battery housing under sealed cover
- Relay grouping adjacent to high-amperage slots
- Spare inserts stored inside panel cover
