Hello friends, I have problems with an automatic Kia Sorento,
intermittently igniting the traction control lights and ABS in addition to the relegation light and on occasion activates the brake without applying the pedal.
In addition, the steering wheel controls for radio control operate the volume control erratically change the emitting the mute button rises the volume and thus by order a whole disaster.

Please someone who has the electrical diagram of this vehicle or some similar experience to be able to solve it, I thank you in advance.

Please have the motor and year of the vehicle
