Access the main power distribution module behind the driver-side kick panel to check relays and protective units controlling engine, lighting, and interior circuits. Verify terminal labels before handling components to avoid misrouting current.
Measure voltage at each connector with a digital multimeter to confirm steady supply across ignition, cooling, and auxiliary circuits. High-current lines feeding the starter or radiator fan require careful observation for signs of resistance or corrosion.
Document each slot’s amperage and purpose using a photo or written chart. This record helps trace auxiliary electronics like aftermarket lighting or stereo amplifiers and prevents accidental overload when replacing modules.
Inspect terminals for discoloration or melted plastic which can indicate overheating. Clean contacts with electrical cleaner and tighten screws to restore proper connectivity before installing new protective units.
Handle replacements individually to maintain proper sequence and circuit integrity. Confirm each new module matches the original amperage and seating to ensure reliable operation of all vehicle systems.
2017 SUV Electrical Panel Layout
Locate the main power distribution module behind the driver-side kick panel to access relays and protective elements for engine management, interior lighting, and auxiliary systems. Check labels on each slot before touching connectors.
Verify voltage across terminals with a digital multimeter to confirm steady supply to starter, cooling fan, and ignition circuits. High-current lines may show slight discoloration, indicating past overheating that should be addressed.
Check the engine compartment power center for modules controlling ABS, fuel pump, and large lighting circuits. Use the slot labels to trace each circuit and identify which protective elements correspond to specific systems.
Clean corroded or discolored terminals using electrical contact spray. Tighten screws on each connector to restore stable contact and reduce the risk of intermittent operation or voltage drops.
Document each protective element’s rating and position on a reference sheet or photograph. This helps when adding aftermarket devices such as auxiliary lighting, stereo amplifiers, or trailer wiring to avoid overloading existing circuits.
Test relays individually by removing them one at a time and checking continuity and voltage under load. Replacing only faulty units prevents unnecessary system interruptions and keeps circuits organized.
Label all aftermarket connections separately to track additional draw on the original power distribution. Proper labeling allows safe troubleshooting if auxiliary systems interfere with standard vehicle electronics.
Reassemble the modules carefully, ensuring each protective element fits securely in its designated slot and matches the original amperage rating. This maintains consistent operation for engine, lighting, and interior circuits without causing shorts or overloads.
Locating Interior and Engine Compartment Panels
Access the interior electrical panel behind the driver-side kick panel. This compartment houses low- and medium-current protective elements for cabin lighting, infotainment, and turn signals. Verify slot labels and color-coded modules before testing or removal.
Locate the engine compartment distribution center near the battery and main relay cluster. It contains high-amperage modules for the starter, radiator fan, ABS, and fuel pump circuits. Check the cover label for each slot to identify the corresponding system.
Use a systematic approach to trace circuits:
- Document each module’s rating and location on a reference sheet or photo.
- Mark any aftermarket connections like auxiliary lights or trailer wiring.
- Inspect terminals for corrosion or melted plastic before reconnection.
This prevents misrouting current and ensures proper operation after maintenance or upgrades.
Handle replacements and testing one module at a time to maintain circuit integrity. Measure voltage and continuity across terminals, tighten loose connections, and ensure each unit fits securely in its designated slot for reliable performance of engine and interior systems.
