Why is the brake light of Dongfeng Fengguang 580 always on?
2 Answers
If the brake light of Dongfeng Fengguang 580 remains constantly illuminated, it indicates a potential system malfunction. It is recommended to use an automotive diagnostic scanner at a repair shop, where technicians will perform corresponding repairs based on the fault codes. Below are relevant details: 1. Possible causes: During driving, the force applied to the brake pedal is transmitted through the master cylinder piston, which sends brake fluid to each wheel's brake cylinder. This action causes the brake pads to contact the wheels, thereby achieving braking. Insufficient brake fluid is often accompanied by noticeably reduced braking power, and in severe cases, complete loss of braking force may occur. Low brake fluid levels can cause the brake pedal to sink, keeping the brake switch continuously energized and resulting in constant illumination of the brake light. 2. Powertrain: The Fengguang 580 is equipped with two engine options: a 1.8L naturally aspirated engine and a 1.5L turbocharged engine. The 1.8L naturally aspirated engine delivers 139 horsepower with a maximum torque of 187 N·m, featuring multi-point fuel injection technology, and utilizes an aluminum cylinder head with cast iron cylinder block.
When using my Dongfeng Fengguang 580, the brake lights stayed on constantly, which is usually caused by a faulty brake light switch. The switch might be stuck in the on position without resetting, such as when the pedal doesn't return; it could also be due to a short circuit in the wiring. A common scenario is internal sticking or spring failure in the switch causing the lights to stay on. Also, check if the fuse is blown or if there's a grounding issue. Try pressing the pedal a few times to see if it resolves the problem. Safety first—constant brake lights can mislead trailing vehicles into rear-ending you and also drain the battery. It's advisable not to drive on the highway and instead head straight to a repair shop to replace the switch or inspect the circuit. During regular maintenance, keep the switch area clean to prevent dust buildup and avoid similar issues, saving you the hassle of a breakdown. This is quite common, and many car owners have encountered it. Don't delay—get it fixed for peace of mind.
