What to Do When the Electronic Parking Brake System Fails in a Car?

The solution to an electronic parking brake system failure in a car is to reset the electronic parking brake. The specific steps are as follows: First, turn on the car key, then press the foot brake, hold down the electronic handbrake for 5 seconds, and then pull up the electronic handbrake for another 5 seconds to complete the initialization reset. The function of the electronic parking system is to provide accurate parking force through the slope sensor controlled by the controller. When starting, the parking control unit calculates information provided by the clutch distance sensor, clutch engagement speed sensor, throttle pedal sensor, etc. The parking brake is automatically released when the driving force exceeds the running resistance, allowing the car to start smoothly.
When encountering an electronic parking brake system failure, I immediately take safety measures. Never park on a slope, as this may cause the vehicle to slide or roll dangerously. I prioritize finding a flat area to park, engaging the mechanical handbrake as a temporary substitute to ensure the vehicle remains stable. Then, I check the dashboard for any other warning lights, such as the battery or engine light. If only the parking system light is on, it might be due to sensor dust accumulation or loose wiring. I try turning off the engine, opening and closing the door, waiting for 5 minutes, and then restarting the system to see if it resets. However, in most cases, I can't resolve it myself, so I call a towing service to take the vehicle to the nearest repair shop for diagnosis. Remember, brake system issues involve core safety, and driving is absolutely not an option. When parking normally, avoid frequent use of the electronic parking brake, especially in cold weather when failures are more likely—prevention is better than repair.
