1. Understanding Electronic Parking Brake (EPB) Systems

The Electronic Parking Brake (EPB) system is a modern automotive safety feature that replaces the traditional manual handbrake with an electronic system. Instead of pulling a lever or pressing a pedal, drivers activate the parking brake with a simple push of a button or switch.

1.1 How EPB Systems Work

EPB systems use an electronic control unit (ECU) to control actuators at the rear wheels, which apply and release the brakes. These actuators can be either:

• Motor-on-Caliper (MoC) systems: Each rear brake caliper has an integrated electric motor that directly applies the brake.
• Cable-Puller systems: An electric motor pulls cables that actuate the parking brakes.

1.2 Why EPB Service Functions Are Necessary

Servicing EPB systems requires specialized procedures because of their electronic nature. Traditional brake service methods are not sufficient and can even damage the system. Key EPB service functions include:

• Putting the EPB into Service Mode: Retracts the brake pistons to allow for brake pad replacement.
• Calibrating the EPB: Ensures the correct clamping force after brake service.
• Activating and Deactivating the EPB: Tests the functionality of the EPB system.
• Reading and Clearing Diagnostic Trouble Codes (DTCs): Identifies and resolves issues within the EPB system.

2. The Role of OEM Tools in EPB Service

OEM (Original Equipment Manufacturer) tools are diagnostic devices designed and used by car manufacturers. These tools offer comprehensive access to vehicle systems, including the EPB.

2.1 What are OEM Tools?

OEM tools, also known as factory scan tools, are the primary diagnostic equipment used by dealerships and authorized service centers. These tools are made by or for the vehicle manufacturer and are designed to work seamlessly with their vehicles.
