Locate the primary panel under the dashboard on the driver’s side to quickly identify circuits controlling lighting, climate systems, and infotainment modules. Each receptacle is clearly marked with amperage ratings, making it easier to replace or test individual connectors without guesswork.
Consult the secondary compartment beneath the hood for high-current relays and protective devices linked to the engine, cooling fan, and main electrical harness. The layout is designed to allow fast removal of a faulty link while minimizing interference with surrounding components.
Use the printed legend inside the cover to match numbered terminals with their corresponding systems. This ensures that any maintenance, whether swapping a protective element or diagnosing a circuit, proceeds safely and efficiently without risking shorts or misalignment.
Regular inspection of these panels helps identify signs of overheating or corrosion before they affect performance. Keeping connectors clean and seated properly maintains consistent power flow to all modules, preventing intermittent faults or warning indicators from appearing unexpectedly.

Locate the power distribution unit under the driver’s side dashboard for quick access to relays and amperage holders. Each slot is labeled with its corresponding circuit, including lighting modules, infotainment power, and climate control circuits. Always check the miniature legends printed inside the cover for slot identification before handling any connectors.
For circuits controlling high-demand components like the main fuel pump or ABS system, the holder rating is typically 20–30 amperes. Avoid replacing these with mismatched ratings; doing so can trigger short circuits or permanent module failure. Use a digital tester to verify current flow before reconnecting the cover.
Passenger Compartment Panel Tips
The interior distribution unit near the glove compartment contains smaller capacity holders, usually ranging from 5–15 amperes, for interior electronics and sensors. When swapping modules, observe the metal clip orientation to prevent bending or poor contact. Labeling spare holders with masking tape can prevent confusion during maintenance.
External panels under the hood control engine management and auxiliary power points. Slots are color-coded to differentiate between high-current and low-current circuits. Cross-reference the small schematic inside the lid with the vehicle’s service manual to identify circuits like ignition control, radiator fan, and trailer wiring.
For troubleshooting, remove one holder at a time and inspect the filament or metal strip inside. Blackened or broken strips indicate a blown unit. Replacing only the defective component avoids unnecessary replacements and preserves the integrity of the electrical harnesses.
Locating the Electrical Control Units Across Model Years
For vehicles manufactured between 2010 and 2012, the primary electrical access unit is positioned beneath the dashboard on the driver’s side. Slide the panel downward and you will see a rectangular enclosure containing labeled circuits for interior lighting and ignition components.
Models from 2013 to 2015 moved the compartment closer to the center console, near the passenger footwell. Access requires gently removing a small plastic cover; inside, a series of relays and protective elements are neatly arranged with numerical identifiers.
2016 through 2017 versions relocated the protective panel to the engine compartment. Look adjacent to the battery, where a black plastic casing houses multiple modular connectors. This area also contains high-amperage terminals for major engine and climate systems.
Vehicles built in 2018 and 2019 retain a dual-location setup. One enclosure remains inside the cabin, just above the glove compartment, while the other resides in the engine bay, toward the firewall. Interior units usually handle auxiliary and infotainment circuits, whereas exterior units manage propulsion and cooling circuits.
Stepwise Access Tips
- Confirm the year of manufacture from the VIN before attempting removal.
- Use a flashlight to identify small tabs that secure interior panels.
- Do not force any cover; gentle pressure releases most plastic clips.
- Note any circuit markings before disconnecting connectors.
From 2020 onward, manufacturers consolidated protective enclosures under the hood. The casing is typically near the windshield base on the driver’s side. This position simplifies inspection of high-load systems and eliminates the need for interior panel removal for major checks.
Older models, pre-2010, often store the protective module beneath the steering column. Lift the lower trim and check for a rectangular housing with a removable lid. Some units feature a snap-on diagram inside the cover, identifying each circuitry point.
