my Honda Pilot YF3 (2016-2022) lights are flickering what does this mean

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Ensure that the vehicle is on a flat surface and securely parked.

2. Inspect and Clean Battery Terminals

• Remove the battery terminals (negative first, then positive).
• Clean the terminals and cable ends using a wire brush and a mixture of baking soda and water to neutralize corrosion.
• Reattach the terminals securely, ensuring no corrosion remains.

3. Test and Replace Battery (if necessary)

• Use a multimeter to check the battery voltage.
• If voltage is below 12.4 volts, consider charging the battery or replacing it if it's old or failing.
• Install a new battery if replacement is needed, ensuring correct polarity.

4. Test and Replace Alternator (if necessary)

• Start the vehicle and measure voltage at the battery terminals with a multimeter.
• If voltage is below 13.8 volts while running, the alternator may need testing or replacement.
• Remove the alternator and replace it if faulty, following manufacturer specifications for installation.

5. Inspect and Repair Wiring

• Visually inspect the wiring harness for frays, breaks, or loose connections.
• Repair or replace any damaged wiring.
• Ensure all ground connections are clean and tight.
