This code means there's a problem with the buttons or controls that help your car keep a steady speed on the highway.
The P0564 code indicates an issue with the cruise control system's input circuit, specifically with the multi-function input 'A'.
The P0564 code is triggered when the Powertrain Control Module (PCM) detects a malfunction in the cruise control multi-function input circuit. This circuit is responsible for sending signals from the cruise control switches (such as ON, OFF, SET, RESUME) to the PCM, allowing it to maintain a set speed.
