Troubleshooting Brake Light Issues in a Mitsubishi Mirage

Begin by checking the brake light switch, as this is often the most common culprit for malfunctioning lights. Ensure that the switch is properly engaged and functioning; if it appears faulty, replacing it is a straightforward fix. Next, inspect the wiring harness that connects the brake switch to the bulbs. Look for any signs of frayed wires or loose connections, as these can disrupt the electrical flow. If the brake lights still do not work, examine the vehicle’s fuses and relays, as a blown fuse can easily lead to light failure. Additionally, consider checking the wheel speed sensors and the ABS module, especially if the ABS warning light is illuminated on your dashboard. By following this diagnostic approach, you can efficiently identify and resolve the issue, ensuring your brake lights operate correctly and enhancing your vehicle's safety. Regular maintenance and prompt attention to these components will help prevent future problems.
