Code C1270 Description

The Electric Parking Brake (EPB) system is the parking brake device which is used instead of the conventional hand-break system. When a driver presses the EPB button, the button signal is delivered to the EPB ECU and then the EPB actuator which consists of a motor and a gear is activated. At this time, while the motor in the EPB actuator rotates, the motor pulls the EPB cable connected to the rear wheels. Among components of the EPB system, the motor is installed inside of EPB ASS'Y. When the motor gets the EPB ECU's order, it is operated and gets parking cables to be moved through the gear box.
