What does emergency brake assist failure mean?
2 Answers
The warning indicates that the brake fluid reservoir in the engine compartment needs to be refilled with automotive brake fluid. Here are the relevant explanations: 1. Fault occurrence: If the vehicle's brake pads are malfunctioning, you should promptly visit an authorized 4S store or repair shop for inspection to resolve the auxiliary braking system failure issue. 2. Brake assist system: This system compensates for ABS deficiencies by utilizing sensors on both the accelerator and brake systems to monitor the driver's operation of these pedals. When it detects the driver suddenly pressing the brake pedal with extreme speed and force, the system will interpret this as requiring emergency braking.
That day while driving on the highway, I suddenly saw this warning light illuminate on the dashboard, and my heart skipped a beat. After checking the information, I learned that this is a sign of a malfunction in the emergency brake assist system. It means that when you suddenly slam on the brakes and need extra braking force, this intelligent system can't automatically give you that additional push. Under normal braking conditions, you might not notice anything wrong, but in case of a sudden stop by the car ahead or someone darting out, the braking distance could significantly increase, posing a danger. When I took it to the repair shop, the mechanic said common causes include the wheel speed sensor being clogged with mud or poor circuit connections leading to data transmission failures. In the past six months of driving, I've encountered this issue twice. The first time was after rain when mud got into the sensor, and washing it with water fixed the problem. The second time, it cost over 300 yuan to replace a wiring harness, which completely resolved the issue.
