What is the fault when the Great Wall C30's hazard lights flash while braking?
3 Answers
The hazard lights flashing when braking in the Great Wall C30 is actually a hidden feature of the vehicle, known as the brake strobe mode. To turn off this function, simply press and hold the hazard light switch for 3 seconds while the vehicle is running. Below is an introduction to the Great Wall C30: 1. Dimensions: The Great Wall C30 is a compact sedan under the Great Wall brand, with a wheelbase of 2610 mm, and a length, width, and height of 4471 mm, 1705 mm, and 1480 mm respectively. 2. Powertrain: The Great Wall C30 is equipped with a 1.5-liter naturally aspirated engine across all models. This engine delivers 106 horsepower and a maximum torque of 138 Nm, with peak torque achieved at 4200 rpm and maximum power at 6000 rpm. The engine features VVT technology and multi-point fuel injection, and utilizes an aluminum alloy cylinder head and block. It is paired with either a 5-speed manual transmission or a 6-speed AMT mechanical automatic transmission. 3. Suspension: The Great Wall C30 uses a MacPherson independent suspension at the front and a torsion beam non-independent suspension at the rear.
Every time I step on the brake, the hazard lights come on, which is quite common on the Great Wall C30. There could be several possible reasons: a faulty brake switch is the main culprit, causing signal confusion that triggers the hazard lights when pressed; a short circuit or grounding issue in the wiring, causing erratic current flow; or a malfunctioning hazard light relay or control unit. From my experience, don't mess with the electrical system yourself—first, check the brake fuse in the fuse box to see if it's blown; if that's fine, use a multimeter to test the wiring. This issue is quite annoying—when driving, others might think you're signaling a hazard, which can mislead following cars and drain the battery. I recommend heading to a repair shop for diagnosis as soon as possible. Small fixes aren't expensive, but delaying could lead to burnt-out filaments, which is even more troublesome. During regular maintenance, remember to inspect the lighting system—don't overlook minor issues. Safety comes first, so don't skimp on necessary expenses.
I encountered this issue while driving—the hazard lights would flash when I hit the brakes. At first, I thought my old car was just acting up. Common causes include a worn-out brake light switch sending erratic signals that trigger the hazards, or loose wiring harnesses short-circuiting after rain exposure. The control module might also be faulty. My advice: don’t panic. First, check if your trunk light works—if it does, it’s likely just a faulty switch, which costs a few bucks to replace. If that doesn’t fix it, visit a technician to diagnose wiring with proper tools. This glitch is especially annoying in city traffic, with cars behind honking at you. Remember to regularly inspect light connectors, clean dust, and prevent rust to nip problems in the bud. After the fix, driving feels much smoother and safer.
