C1526 KIA Description

When a vehicle goes down the hill, just pushing the Downhill Brake Control (DBC) switch enables the car to keep its vehicle’s speed at a constant value without operating the brake pedal. The DBC function is operated when the vehicle is on the decline and its velocity is under the predetermined speed. The Hydraulic Electronic Control Unit (HECU) monitors the Downhill Brake Control (DBC) switch. The HECU sets the OBDII code when the Downhill Brake Control (DBC) switch is not to factory specifications.
