General Information

Component Location





General Description

The Downhill Brake Control (DBC) function helps the driver control the vehicle when going down a steep hill. When a vehicle goes down hill, pushing the 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.

DTC Description

The HECU monitors the brake lamp relay (DBC relay) for normal operation. If there is an open or a short in the relay circuit, this DTC is set.
