Locate the primary power module behind the passenger-side kick panel for direct access to circuits controlling headlights, fuel injectors, and ignition relays.
Verify amperage ratings printed on each protective unit before removal or replacement. Low-current circuits typically range from 5A to 15A for interior electronics, while high-current units reach 30A to 40A for starter and cooling fan relays.
Disconnect the negative battery terminal before touching any modules to prevent short circuits. Use a plastic tool to lift connectors and avoid metal contact that could damage electronic control units.
Document all positions of modules and connectors with photos or notes prior to removal. Accurate tracking ensures correct reinstallation and maintains power to essential systems like ABS, fuel pump, and engine management electronics.

Access the main electrical module on the driver side near the battery. Release the plastic cover by pressing the retaining clips and lift it to reveal the circuit components.
Identify each protective unit using the printed amperage and function labels. Key circuits include:

- 5A to 10A for interior lighting and dashboard indicators
- 15A to 20A for wipers, horn, and power mirrors
- 30A for radiator fan and ignition relay
- 40A for starter and main power relay
Disconnect the negative battery terminal before removing any modules to prevent short circuits. Use a plastic pry tool for connectors to avoid contact with metal surfaces.
Document all connections before removing modules. Photos or labeled notes ensure correct reinstallation and prevent loss of power to engine controls, fuel pump, and ABS system.
Inspect each module for signs of corrosion, burnt contacts, or loose terminals. Replace any damaged unit to maintain reliable operation of the vehicle’s electrical system.
Test continuity with a multimeter to verify proper function. Circuits that show irregular readings should be replaced immediately to avoid failures in lighting, ignition, or other electronic accessories.
Locating the Main Power Module

Access the primary electrical module on the driver side near the battery. Remove the plastic cover by pressing the retaining clips to reveal the circuit components for inspection and maintenance.
Check for high-current relays inside the panel. Critical units control the starter, radiator fan, and ignition system. Handle these carefully and confirm amperage ratings before touching any connectors.
Use proper tools and documentation when working with the module:
- Plastic pry tools prevent accidental shorting of terminals
- Take photos or label connectors for correct reinstallation
- Inspect the housing for cracks or corrosion to avoid exposure to moisture
