2017-10-10

Description:

  • The fault code P0856 pertains to an issue with the traction control input signal. This code typically indicates a problem with the electrical circuitry or connection associated with the traction control system, which is responsible for monitoring and controlling the traction of the vehicle during acceleration or when road conditions are slippery.

Possible Symptoms:

  • Malfunction Indicator Lamp (MIL) or Check Engine Light illuminated

  • Traction control system not functioning properly or disabled

  • Loss of traction control during acceleration or on slippery road conditions

  • Erratic behavior or inconsistent operation of the traction control system

  • Potential limited drivability due to the issue with the traction control input signal

Possible Causes:

  • Faulty traction control switch

  • Wiring or connection problems in the traction control input circuit

  • Loose or corroded connectors in the traction control system

  • Faulty traction control module or ABS module

  • Intermittent issues with the traction control input circuit

Related Parts:

  • Electronic Brake: Brakes controlled by an electric current. Problems lead to inefficient braking

Possible Solutions:

  • Test and replace the faulty traction control switch, if necessary

  • Inspect and repair the traction control input circuit for any issues, such as damaged wires or connectors

  • Ensure the connectors in the traction control system are secure and free from corrosion

  • Test and replace the faulty traction control module or ABS module, if necessary

  • Inspect the traction control input circuit for any intermittent issues and repair as needed
