Electronic Parking Brake Malfunction
In brief, electric parking brake malfunctions stem from problems related to electronic components, sensors, programming, or power supply. Signs of a malfunctioning electric parking brake may comprise failure to engage or release, warning lights, atypical sounds, and vehicle immobility.
The electric parking brake may fail to release due to a malfunction in the brake pedal switch or gear stick selector switch, a miscommunication between the EPB module and these switches, or an electrical fault in the EPB module or actuator.
What can cause an electric parking brake to malfunction?
The electric parking brake (EPB) system can malfunction due to a variety of reasons, including issues with the switches or wires connecting the actuator and module. Broken, opened, or shortened wires, as well as high resistance, can also contribute to the problem. Additionally, low system voltage or an open fuse can cause the EPB system to function improperly.

Can you release an electric parking brake without switching on the ignition?
It is unlikely to release an electric parking brake without switching on the ignition due to the challenges of the system's diagnostics and servicing. Additionally, a failure in the electrical system may result in the parking brake not releasing.
If the electric parking brake fails to release either manually or automatically, it may be caused by multiple factors. These potential causes include a faulty brake pedal switch or gear stick selector switch, a communication error between the EPB module and either of the switches, or an electrical fault within the EPB module or actuator. It is recommended to seek professional assistance in diagnosing and resolving the issue to ensure the safe operation of the vehicle.
How do you reset an electric parking brake?

What does it mean to switch from manual to electronic parking brake?
Switching from a manual parking brake to an electronic one means that the braking system is no longer operated via a physical lever mechanism but instead through electronic means. This can pose a challenge in the event of an electrical system failure, which may render the electronic parking brake inoperable and not release.
Electric parking brake problems include stuck or damaged caliper piston motors, malfunctioning buttons, wiring issues, low battery voltage, and system reset or programming errors. These issues can lead to ineffective parking brakes, compromising the safety and functionality of the vehicle.
