What is the solution for the EPB malfunction in a car?

The solution for the EPB malfunction in a car is: press the foot brake down while simultaneously pressing the handbrake down, hold for about 20 seconds, and then lift the handbrake up to restore normal operation. EPB stands for Electrical Park Brake, which is the electronic parking brake system, also known as the electronic handbrake. An EPB malfunction is likely due to a fault in the electronic handbrake. Since an electronic handbrake malfunction could be caused by issues with components such as the wheel speed sensor, throttle position sensor, handbrake switch, wheel speed sensor, or motor, any abnormality in these parts could trigger the EPB light to illuminate. Therefore, it is recommended that car owners take their vehicle to a repair shop for inspection. A diagnostic tool can quickly and accurately identify the source of the malfunction.
I've dealt with quite a few issues regarding the Electronic Parking Brake (EPB) system in cars. The most common causes are stuck buttons or dust accumulation on sensors. If you find the EPB isn't working, first check if the button presses smoothly – sometimes it just gets stuck and is easy to fix. Additionally, dirty sensors can cause false alarms; try gently wiping them with a damp cloth to see if there's any improvement. If the button isn't responsive, there might be unstable circuit connections – you can try turning off the engine and restarting the system. However, remember never to attempt manual release on a slope; it's dangerous if it fails to engage. When in doubt, always call for roadside assistance or visit a repair shop – safety comes first.
I found that EPB issues are often related to the battery, such as voltage instability or loose wiring harness connections. Try these simple steps: First, check if the EPB fuse in the fuse box is blown and replace it with a new one. Then, inspect the battery terminals for looseness and tighten them if necessary. If that doesn't work, perform a complete power reset by disconnecting the battery's positive and negative terminals for a few minutes to reboot the system, which often resolves temporary glitches. If the EPB still doesn't respond after manual release, it might be a faulty relay requiring professional repair to avoid compromising braking safety. Remember, it's safer to perform these checks in your own garage rather than on the roadside.
