The automobile fault code P0858 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.

P0858: Understanding The Transmission Range Sensor Circuit High Input
The P0858 fault code refers to a low traction control input signal.
This means that when the traction control system is active, the Electronic Brake Control Module (EBCM) sends a message to the Engine Control Module (ECM) requesting torque reduction. However, if certain ECM diagnostic trouble codes (DTCs) are set, the ECM will be unable to perform the torque reduction for traction control.
As a result, a serial data message is sent to the EBCM indicating that traction control is not allowed.
This fault code indicates a problem with the input signal for traction control, which can affect the system’s ability to reduce torque for improved traction.
FAQ
