What is the fault when the Great Wall C30's hazard lights flash when braking?
2 Answers
The Great Wall C30's hazard lights flashing when braking is a hidden feature of the Great Wall C30, not a fault issue. This function is the brake strobe mode. To turn off this function, simply hold the hazard light switch for 3 seconds while the vehicle is running. Below is a detailed introduction of the Great Wall C30: Overview: The Great Wall C30 is a global strategic model that Great Wall Motors has devoted efforts to create and newly developed. It took 4 years from development to market launch, and its development design and testing were completely conducted according to EU standards, inheriting Great Wall Motors' consistent excellent quality and solid craftsmanship. The vehicle is stable and practical while also being dynamic and stylish. Power: As a compact sedan equipped with a 1.5L VVT engine, it is positioned as an important strategic model for Great Wall, marking Great Wall's ambition to make a big impact in the civilian vehicle market. The 1.5L VVT engine, paired with both MT and CVT transmission modes, provides users with more choices.
When the hazard lights also come on while braking, it may be due to a short circuit or cross-connection between the brake light switch and the hazard light control circuit. The brake light switch is responsible for sending signals to the rear taillights, but if the wiring is aged or the switch is damaged, current may mistakenly flow into the hazard light system, causing the hazard lights to illuminate along with the brake lights. Additionally, checking whether the fuse is blown is crucial; if the fuse is faulty, the entire circuit will be affected. I've also encountered issues with poor grounding—loose screws causing poor current return paths, leading to similar malfunctions. It's recommended that you first try disconnecting the wiring connectors near the dashboard and use a multimeter to test for continuity; if you don't have the tools, go directly to a professional repair shop to inspect and replace the switch assembly—this is a matter of driving safety and shouldn't be delayed. Regular maintenance of the wiring to avoid corrosion can help prevent such issues.
