What does it mean when the brake warning light is on in a Haval vehicle?

Haval brake warning light being on indicates a fault in the vehicle's braking system. In such a situation, you should immediately pull over to the side of the road and inspect the vehicle. If necessary, you can call for professional assistance to prevent potential safety hazards and traffic accidents while driving. Taking the 2021 Haval H6 Third Generation 2.0T Automatic Two-Wheel Drive Max as an example: it is a compact SUV launched by Great Wall Motors, with dimensions of 4653mm in length, 1886mm in width, and 1730mm in height, and a wheelbase of 2738mm. It is equipped with a 2.0T turbocharged engine, delivering a maximum power of 155kw and a maximum torque of 325nm, paired with a 7-speed dual-clutch transmission.
That day when I was driving my Haval H6 to pick up my kid, a red exclamation mark light suddenly appeared on the dashboard. Later, I found out it was a brake light failure warning. When this light comes on, there's an 80% chance there's an issue with the rear brake lights. The most common cause is a burnt-out bulb, especially during winter when the temperature changes can easily damage the bulb. If replacing the bulb doesn't fix it, you should check if the circuit connector has poor contact. Once, I found a loose plug, and just reinserting it tightly solved the problem. Additionally, you need to inspect the brake pedal sensor switch, as aging plastic parts can cause signal failure. A blown fuse is also a common issue. The mechanic told me that not fixing this problem promptly is particularly dangerous because other drivers won't see you slowing down, increasing the risk of a rear-end collision, especially at night or in rainy weather. So, when you see this light on, it's best to immediately check if all the rear lights are working.
Last time I helped my dad check his Haval M6, we encountered this warning light. The brake light system has three layers of protection: bulbs, circuits, and the control system. The most common issue is bulbs burning out naturally at the end of their lifespan, especially with frequent braking in city driving. Circuit problems are more troublesome, such as wires being gnawed by rodents or connectors oxidizing and rusting. The worst-case scenario is an error from the electronic control unit, which requires a diagnostic scanner to read the fault code. Here's a lesser-known fact: Haval's body control system is highly sensitive to current differences between left and right lights—even a 30% brightness reduction in one bulb can trigger a warning. It's recommended that owners keep two spare bulbs in the glove compartment for quick replacement when needed.
