why does my Honda Accord 9th Generation (2013-2017) brake light stay on

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Check Brake Fluid Level

• Locate the master cylinder reservoir under the hood.
• Inspect the brake fluid level; if it's low, top it off with the correct type of brake fluid (DOT 3 or DOT 4).
• If the fluid is low, check for leaks in brake lines or fittings.

3. Inspect and Replace Brake Light Switch

• Locate the brake light switch near the brake pedal.
• Disconnect the electrical connector from the switch.
• Remove the switch from its mounting bracket.
• Install the new brake light switch in reverse order, ensuring it is adjusted correctly.
• Reconnect the electrical connector.

4. Test Brake Pedal Position Sensor

• If equipped, locate the brake pedal position sensor.
• Disconnect the wiring harness from the sensor.
• Use a multimeter to check for continuity and proper voltage as per manufacturer specifications.
• Replace the sensor if it is faulty.

5. Reconnect Battery and Test

• Reconnect the battery.
• Start the vehicle and press the brake pedal to check if the brake light turns off.
