[SOLVED] P0859 Code: Traction Control Input Signal High – How To Fix It!

The automobile fault code P0859 indicates a problem with the Electronic Brake Control Module (EBCM).

The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.

The cause of this fault code can be a faulty EBCM, an open or shorted EBCM harness, a poor electrical connection in the EBCM circuit, or a faulty Engine Control Module (ECM).

To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0 hour. It is important to address this fault code promptly to ensure the proper functioning of the vehicle’s braking system.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p0859 fault code.

  • The symptoms of the automobile fault code p0859 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p0859 can be caused by a faulty Electronic Brake Control Module (EBCM), an open or shorted EBCM harness, a poor electrical connection in the EBCM circuit, or a faulty Engine Control Module (ECM).

  • The fault code p0859 can be caused by a faulty Electronic Brake Control Module (EBCM), an open or shorted EBCM harness, a poor electrical connection in the EBCM circuit, or a faulty Engine Control Module (ECM).

To fix the automobile fault code p0859, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0859, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded pins in the connectors.
  • This fix should take approximately 1.0 hour.

The automobile fault code p0859 diagnosis and fixing cost is influenced by the estimated repair time of 1.0 hour.

Most auto repair shops charge between $75 and $150 per hour for their services.

The P0859 fault code refers to a problem with the traction control input signal being too high. This occurs when the Electronic Brake Control Module (EBCM) sends a message to the Engine Control Module (ECM) requesting torque reduction for traction control.

However, if certain ECM diagnostic trouble codes (DTCs) are present, the ECM is unable to perform the torque reduction. As a result, a message is sent to the EBCM indicating that traction control is not allowed.

This fault code indicates a high input signal for traction control, which can affect the performance of the system.

What are the possible causes of the automobile fault code p0859?

If you see the engine light or service engine soon warning light on, the fault code P0859 could be the culprit. This code is often caused by a faulty Electronic Brake Control Module (EBCM), an open or shorted EBCM harness, a poor electrical connection in the EBCM circuit, or a faulty Engine Control Module (ECM). To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the fault code p0859?

If you’re dealing with the fault code p0859 and your engine light is on, it’s time to visually inspect the wiring harness and connectors. This could be caused by a faulty Electronic Brake Control Module (EBCM), an open or shorted EBCM harness, a poor electrical connection in the EBCM circuit, or even a faulty Engine Control Module (ECM). To fix it, check the possible causes mentioned earlier and visually inspect the wiring harness and connectors. Look out for damaged components and check for any broken, bent, pushed out, or corroded pins in the connectors.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p0859?

When resolving the fault code p0859, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. By doing so, you can identify any faults in the Electronic Brake Control Module (EBCM) or Engine Control Module (ECM) and address them accordingly. Don’t forget to check for open or shorted EBCM harness and poor electrical connections.

p0859 error fault code explained

If your engine light is on and you’re seeing the P0859 fault code, it could be due to a faulty Electronic Brake Control Module (EBCM), an open or shorted EBCM harness, a poor electrical connection in the EBCM circuit, or a faulty Engine Control Module (ECM).

To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look out for broken, bent, pushed out, or corroded connector pins.
