why does my Honda CR-V Sixth Generation (2023-present) dashboard lights flicker while driving

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Battery Connections

• Remove the battery terminals (negative first, then positive).
• Clean the terminals and battery posts with a wire brush or terminal cleaner.
• Reattach the terminals securely, starting with the positive terminal.

3. Test and Replace the Battery (if necessary)

• Reconnect the battery and use a multimeter to test voltage.
• If the voltage is below the normal range, consider replacing the battery.
• To replace the battery, remove the battery hold-down bracket and lift out the old battery. Install the new battery and secure it with the bracket.

4. Check and Test the Alternator

• Use a multimeter to measure the voltage at the alternator while the engine is running.
• If the output is below 13.7V, the alternator may need to be replaced.
• To replace the alternator, disconnect the battery, remove the serpentine belt, and unbolt the alternator from its mount. Install the new alternator and reconnect the belt.

5. Inspect Wiring and Ground Connections

• Visually inspect wiring harnesses for frayed wires or signs of wear.
• Ensure all ground connections on the chassis and engine block are clean and tight.
• Repair or replace any damaged wiring as necessary.
