What is the reason for the excessively fast flashing of the turn signal on the BYD Song MAX?
3 Answers
The excessively fast flashing of the turn signal on the BYD Song MAX may be caused by faults in the turn signal assembly, instrument power distribution box, wiring, and other components. Below is relevant information about the BYD Song MAX: 1. Overview: The BYD Song MAX was officially launched in 2017 as BYD's new MPV model, featuring a 6-seat/7-seat layout. The exterior design of the Song MAX adopts BYD's new "Dragon-Face" design language. In terms of powertrain, it is equipped with a 1.5T turbocharged engine across the lineup. The configuration includes a 12.8-inch central control screen, panoramic imaging, matrix LED headlight assembly, and more. 2. Safety Features: Comprehensive safety configurations: Inheriting the safety genes of the Song platform, it is rich in both active and passive safety features. The body molds are produced by a top Japanese team, utilizing German welding technology, with ultra-high-strength and high-strength steel usage rates exceeding 65%. It also features 8 airbags, ESP, TPMS tire pressure monitoring system, and other comprehensive active and passive safety equipment.
With years of experience in car repairs, the most common reason for turn signals flashing unusually fast is a burnt-out bulb. When the circuit load decreases, the flasher speeds up. Last week, my Song MAX's rear turn signal was flashing rapidly. After checking, I found the right bulb wasn't working. Replacing it fixed the issue. If all bulbs are lit, inspect the flasher relay located in the fuse box—it might be loose or faulty. Worn wiring or water ingress can also cause faster flashing; a simple voltage test with a multimeter can pinpoint the problem. DIY bulb replacement saves money, but always disconnect power to avoid shorts or shocks. Once, delaying a repair nearly caused an accident during a turn, so don't let small issues escalate—timely checks ensure safety. Monthly light inspections make maintenance easy.
When driving the Song MAX, I encountered the turn signal flashing too fast, which initially made me a bit nervous. Later, a friend told me it was due to a burnt-out bulb changing the light signal. Recalling it, the right front light had been intermittently going out earlier. At the 4S shop, the technician confirmed that replacing the burnt bulb would fix it; if the bulb was fine, it might be a faulty flasher or loose wiring, common issues in older cars. I think car owners shouldn't ignore this—incorrect turn signals can affect others' judgment. Once, driving in the rain without fixing it nearly caused a rear-end collision. Now, I've made it a habit to regularly check the exterior lights and their flashing condition. Paying attention to small details can prevent major accidents, making driving safer and simpler.
