Locate the interior and engine compartment electrical panels, then match each numbered slot with its assigned circuit using the cover label. Check high-load circuits first, including ignition supply, cooling fans, and lighting systems.
Each slot has a fixed amperage rating printed on top of the component. Common assignments include infotainment system, climate control, safety modules, and power accessories. Installing a higher rating risks wiring damage, while a lower one can interrupt normal operation.
Inspect terminals for corrosion, loose contact, or heat discoloration. Compact crossovers often experience vibration and temperature shifts that affect connection stability, leading to intermittent electrical issues.
Use a multimeter to verify voltage across both sides of each slot during operation. This method helps detect internal breaks or weak connections that visual checks cannot reveal.

Check the interior and engine bay electrical panels, then match each numbered position with its circuit using the printed legend. Focus first on high-current slots linked to ignition, cooling fans, and main lighting systems.
Each slot is assigned to a specific function and marked with an amperage rating. Lower values such as 7.5A and 10A are typically used for control modules, infotainment, and sensors, while higher values like 30A–50A support motors and heating elements.
The cabin-mounted unit usually handles:
Instrument cluster, audio system, climate control interface, power windows, and driver assistance modules.
The engine compartment unit supports:
Radiator fan motors, ABS system, fuel injection components, and exterior lighting circuits.
Inspect each contact point for oxidation or heat damage. Loose seating can interrupt current flow and cause intermittent faults without visible failure of the component itself.
Use a multimeter to test voltage across both terminals while the circuit is active. If no voltage is present on one side, the component is open and requires replacement with the same rating.
If repeated failure occurs, trace the wiring connected to that slot for insulation damage or short circuits rather than replacing components again.

Check the driver-side lower dashboard first, as the interior electrical block is mounted behind a small removable cover near the steering column. This area handles low to mid power circuits such as infotainment, climate control interface, and power accessories.
In the engine compartment, locate the sealed power distribution unit near the battery. This section manages high-load systems:
- Cooling fan motors
- ABS control unit
- Headlights and exterior lighting
- Fuel injection components
Remove covers carefully using light pressure to avoid damaging clips, then verify slot labels printed inside the крышка before inspecting or replacing any component.
