Hyundai Santa Fe Electric Park Brake Switch

They have separate roles. The switch sends the driver's request; an actuator applies or releases the parking brake under system control. A switch listing does not automatically include the motor.

A mechanical lever operates a different control arrangement. A replacement EPB button is for the vehicle's equipped electronic system and is not a conversion kit for a cable-operated handbrake.

The warning can come from other parts of the system. For example, Toyota describes a parking-brake warning related to a control-module calibration fault on certain vehicles; system diagnosis identifies the cause.

Some electric parking brake systems need a specific service mode before work on the rear brakes so the mechanism can be serviced correctly. Mazda describes such a mode for certain vehicles; the procedure varies by model.

Release conditions can vary. For example, the 2021 Cadillac Escalade procedure calls for the ignition on and the brake pedal applied while operating the switch; use the procedure for your vehicle.
