Does the Electronic Parking Brake Light Stay On After Turning Off the Engine?

[WyattLynn]

After turning off the engine, the electronic parking brake light may stay on for a while. This is due to the car's delayed power-off function. After a certain period, the electronic parking brake light will automatically turn off, which is a normal phenomenon. Most cars have this delayed power-off feature. For example, after the engine is turned off, the headlights may remain on for about 30 seconds to illuminate the road ahead, making it more convenient for the car owner. The electronic parking brake is a technology that uses electronic control to achieve parking braking. Its working principle is the same as that of a mechanical handbrake, both relying on the friction between the brake disc and brake pads to control parking braking. The only difference is that the control method has changed from the traditional mechanical handbrake lever to an electronic button.
