why are my Honda Pilot YF3 (2016-2022) brake lights staying on?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle's battery to prevent electrical shock or short circuits.

2. Inspect and Adjust Brake Light Switch

• Locate the brake light switch, usually mounted near the top of the brake pedal.
• Remove any covers or panels if necessary to access the switch.
• Check the position of the switch; it should be fully depressed when the brake pedal is not engaged.
• If misaligned, adjust the switch by loosening the mounting screws and repositioning it.
• Retighten screws and ensure the switch activates and deactivates correctly.

3. Check for Mechanical Binding

• Inspect the brake pedal for any obstructions or binding points.
• Ensure the pedal returns fully to its resting position after being released.
• If binding is found, lubricate the pivot points or adjust the pedal assembly as needed.

4. Test Brake Light Circuit

• Reconnect the battery.
• Use a multimeter to check voltage at the brake light switch connector with the pedal pressed and released.
• Voltage should be present when the pedal is pressed and absent when released. If not, further inspection of the wiring is needed.

5. Replace Brake Light Switch (if necessary)

• If the switch is faulty, remove it by disconnecting the wiring harness and unbolting it from its mount.
• Install the new brake light switch by reversing the removal process.
• Reconnect the battery and test the brake lights for proper operation.
