Locate the main electrical module under the driver’s side dashboard near the steering column. Disconnect the negative battery cable before handling relays or terminals to prevent shorts and sparks.
Label all connectors and relays using numbered tags or masking tape to track their original positions. This ensures accurate reinstallation without miswiring or creating electrical faults.
Inspect terminals and relay sockets for corrosion, discoloration, or melted insulation. Replace any damaged parts and clean contacts with contact cleaner to maintain stable current flow.
Test each circuit individually with a multimeter on continuity and voltage settings. Activate systems such as headlights, interior lights, and auxiliary outlets to verify proper operation before reconnecting the battery and securing the cover.
Electrical Access Unit Layout for Hyundai i20 2013
Locate the primary electrical module beneath the driver’s side dashboard near the steering column. Ensure the negative battery cable is disconnected before touching any connectors or relays to prevent shorts and sparks.
Label each terminal and relay using masking tape or numbered tags to track their original positions. Inspect the module for signs of corrosion, discoloration, or loose contacts and clean terminals with contact cleaner to maintain reliable current flow.
Test circuits individually with a multimeter for voltage and continuity. Check key systems such as interior lighting, horn, and auxiliary outlets. Reinstall all components securely and verify each function before reconnecting the battery to confirm operational stability.
Locating the Main Electrical Compartment
Access the main electrical module under the driver’s side dashboard near the steering column. Disconnect the negative battery cable before handling any connectors or relays to avoid shorts or sparks.
Remove the lower trim panel by pressing the release tabs on both sides. Keep screws and clips in a small container to prevent loss and ensure the unit can be reassembled correctly.
Illuminate the interior of the compartment with a flashlight to identify all relays, terminals, and high-current connections. Check for discoloration or melted insulation on any component.
Labeling and Documentation
Use numbered tags or masking tape to mark each relay and connector.
- Document the location of headlight and ignition relays
- Mark interior and exterior lighting connections
- Note any auxiliary power terminals
Inspect the module for loose clips or screws and tighten them to maintain secure connections. Verify that all connectors are fully seated in their respective slots before testing circuits.
Testing and Preliminary Checks
Use a multimeter to test voltage and continuity at individual terminals. Check each circuit such as interior lighting, horn, and accessory outlets to confirm proper function before reassembly.
Reinstall the protective cover firmly to prevent debris or moisture from entering the compartment. Secure all tabs and screws to avoid vibration-related disconnections.
Reconnect the negative battery cable and perform a final operational check of all systems. Ensure each relay and terminal engages correctly and that no warning lights are present on the dashboard.
