What does emergency brake assist failure mean?

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.

A few days ago after washing the car, I noticed this yellow warning light pop up on the dashboard. Checking the manual, it says "Emergency Brake Assist Fault." Simply put, the system can't detect when you're emergency braking, so it can't automatically increase braking force. During normal light braking, you won't feel any difference, but if you need to slam on the brakes suddenly, the car won't provide that extra braking assistance like it normally would—basically, the safety feature fails. I remember once on a business trip on the highway, I almost rear-ended a truck because of this issue. First, check if the brake fluid level is sufficient and whether any fuses have blown. If you take it to a repair shop, have them specifically test the wheel speed sensors and the brake control unit circuit.

After the last maintenance, I saw this warning light on. The mechanic patiently explained to me: The so-called emergency brake assist failure actually means the car can't sense when you need to brake hard, so it can't automatically apply maximum braking force in critical moments. It's different from regular braking - you won't need this function during normal slow driving, but it becomes most crucial when driving at night or on slippery wet roads. Common issues include blown fuses or loose sensor wiring connections. When I checked myself, I found metal oxidation in the fuse box - after cleaning it off and reseating the connections, everything returned to normal. Don't ignore this for too long, as it directly relates to driving safety.

As a father of two, I pay special attention to warning lights like this in the car. Emergency brake assist failure means that when there is a sudden collision risk, the system cannot recognize the force of your brake pedal to provide additional assistance. My main concern is when children are playing in the back seat and the driver gets distracted, that's when this safety system is needed as a backup. The problem I encountered was due to the brake pedal sensor being corroded by spilled soda. It only cost a few dozen yuan to replace a small part. By the way, after a system failure, the ABS and electronic stability system may also be affected. It's best to run a computer diagnostic to check for any related fault codes.
