The P0861 fault code refers to a communication issue between the Engine Control Module (ECM) and the Gear Shift Control Module.

The ECM is responsible for monitoring the Gear Shift Control Module, and when it detects a problem in communication, it triggers the OBDII system to set the P0861 code. This code specifically indicates a low communication circuit in Gear Shift Control Module ‘A’. In simpler terms, the P0861 code means that there is a problem with the communication between the ECM and the Gear Shift Control Module.

This can lead to issues with shifting gears and can affect the overall performance of the vehicle. It is important to address this issue promptly to ensure smooth and efficient operation of the transmission system.
