What are the symptoms of a faulty brake light on a Pajero?

[LeIsaac]

The symptom of a faulty brake light on a Pajero is that the brake light does not illuminate. Below are the inspection methods for brake light malfunctions: 1. Check the brake light bulb: Frequent use of the brake light can cause wear on the bulb. If the filament breaks, the bulb will not light up. When the brake light fails to illuminate, inspect whether the bulb is intact. If the bulb is found to be faulty, purchase a bulb of the same specifications and replace it. 2. Check the brake light wiring harness connector: Refer to the circuit diagram to locate the connector in the brake light wiring harness. Unplug the connector and inspect the pins inside for looseness or corrosion. If any issues are found, repair the corresponding pins to resolve the fault. 3. Check the brake light ground wire: The tail lights on the vehicle share a common ground wire. If the ground wire is broken or has a poor connection, the brake light will not function. Therefore, inspect the ground wire. If a problem is found, reconnect it. 4. Check the fuse: If both the bulb and the switch are confirmed to be functioning properly, inspect the fuse. Some vehicles do not have a dedicated brake light fuse and share a fuse with other electrical devices. In this case, check the operation of other electrical devices in the vehicle. If any device is not working, replace the corresponding fuse. 5. Check the brake light switch: If the brake light switch is faulty, none of the brake lights will illuminate. During repair, try connecting the brake light switch with a wire. If the brake light turns on, it indicates that the switch is faulty. In this case, purchase a new brake light switch and replace it.
