The brake light of the Toyota Camry may not work for several reasons: 1. Check the brake light switch first. If the brake light switch is faulty, all brake lights will not illuminate. You can try connecting the brake light switch with a wire; if the light turns on, it indicates that the switch is defective and needs to be replaced; 2. Check the brake light bulb. Due to frequent use, the bulb may wear out, and if the filament is broken, the bulb will not light up. If you find the bulb is damaged, it should be replaced promptly; 3. Check the fuse. If both the bulb and switch are normal, the next step is to check the fuse. Some vehicles share the brake light fuse with other electrical devices, so you need to check the operation of other devices to see if the fuse needs to be replaced; 4. Check the connector in the brake light wiring harness. You can find the connector in the brake light wiring harness based on the circuit diagram and check if the pins inside are loose or corroded. If so, repair is necessary; 5. Check the brake light ground wire. The tail lights share a ground wire, and if this ground wire is broken or poorly connected, it will cause the brake light to malfunction. If there are issues, simply reconnect the ground wire.
