The EPB is the acronym for Electric Parking Brake system. Instead of using pedal or lever, using switch can apply parking brake. Drive controls switch → switch signal to ECU → ECU activate actuator → parking brake Apply/Release. When EPB switch is pulled, parking brake gets Applied. When EPB switch is pushed down, parking brake is released.
EPB ECU sets this DTC if left side motor line is short/open.
