Check the panel cover label first and match each slot number with its assigned system before removing any component, as incorrect placement can disable ignition, lighting, or control modules.
Inside the electrical distribution unit, each position is linked to a specific circuit and marked with a current rating such as 5A, 10A, 15A, 20A, or 30A. Lower values typically support interior electronics like ambient lighting and infotainment, while higher ratings handle power windows, cooling fans, and engine management systems. Always verify the printed value on the component before replacement.
Power is routed from a central supply line into multiple branches, so a single damaged contact may interrupt several systems at once. Inspect terminals for heat marks, looseness, or corrosion, as these issues often cause intermittent malfunctions rather than full shutdown.
Use wire color identification to trace circuits; solid red commonly indicates constant voltage, while striped variants correspond to switched lines. This approach allows targeted diagnostics without removing large sections of wiring or interior panels.

Check the panel cover label first, as it shows slot numbering and circuit assignments for this crossover; align each position with its amperage marking before removing any element. The cabin-mounted power distribution unit typically groups lighting, infotainment, and accessory lines, while the engine compartment unit handles high-load systems such as cooling fans, ABS pump, and ignition control.
Use the printed chart on the inside of the cover to match each slot number with its function; for example, positions in the 5–15A range often correspond to interior electronics, while 20–40A slots serve motors and control modules. Never swap ratings, since higher values can damage wiring insulation and control units.
In the engine bay section, larger blade-type inserts are arranged in rows near the battery housing; these connect to systems like radiator fan relays and fuel delivery circuits. The cabin panel, usually located behind a side trim near the dashboard, contains smaller inserts for audio, climate control, and lighting controls.
Trace circuits by following slot numbers rather than color alone, since manufacturers may reuse colors across different ratings. A multimeter set to continuity helps confirm whether a specific path is intact without relying only on visual inspection.
Keep a printed or photographed chart of the panel layout in the glove compartment, and label any replaced components with their correct rating to avoid confusion during future electrical checks.

Open the driver-side door and remove the side dashboard trim to access the interior power distribution panel; it sits directly behind a snap-on cover near the steering column edge. Use a plastic trim tool to avoid scratching surfaces, and pull straight outward to reveal the rows of blade inserts and relays.
The engine compartment unit is positioned adjacent to the battery housing under a sealed plastic lid; release the retaining clips and lift upward to expose high-current links and control relays. This section handles systems such as cooling fans, ignition supply, and braking electronics, so disconnect the battery negative terminal before touching any component.
For quick identification, follow these reference points:
- Driver cabin panel: left side of dashboard behind removable cover
- Engine compartment panel: next to battery under protective lid
- Secondary relay cluster: near firewall, slightly above main wiring harness
