How to resolve the electronic parking brake warning light?
2 Answers
The electronic parking brake system will illuminate a warning light on the dashboard if a malfunction occurs. To clear the EPB warning light, simply press the brake pedal while simultaneously pushing down the parking brake button, hold for approximately 30 seconds, then release the parking brake. Since there are multiple potential causes for the EPB warning light activation, after clearing the light, it is advisable for vehicle owners to visit a 4S shop or repair facility. Professional technicians can use diagnostic equipment to identify the root cause, enabling prompt resolution of the issue. When the electronic parking brake system malfunctions, continuing to drive the vehicle is not recommended. Doing so may lead to severe wear on the brake pads. Brake pads equipped with sensor wires will trigger corresponding warning lights via the vehicle's computer when worn to their limit position, alerting the driver. For pads without sensor wires, only metallic scraping sounds will be audible when completely worn, posing significant risks to vehicle occupants.
As a veteran driver with decades of experience, I've encountered the electronic parking brake warning light coming on several times. That's usually due to system misjudgment - like when the battery is low it tends to make errors, or when sensors get dirty and interfere with signals. My usual approach is to park, engage the handbrake, and restart the vehicle. If the light remains on, I manually check the foot brake switch or dashboard control buttons - sometimes just removing dust buildup solves it. If that doesn't work, never insist on driving - safety first. This system is connected to the entire braking system, and failure on a slope could be dangerous. I remember last year I found a loose wiring connection - just tightening it fixed the issue. In short, handle simple issues yourself, but for complex problems, head straight to the repair shop or dealership to check sensors and the main module to prevent future trouble.
