Disconnecting The Power Source And Removing The Faceplate

The process of resetting your Pioneer DEH S31BT begins with disconnecting the power source and removing the faceplate. This step is essential to ensure your safety and avoid any potential damage to the device.

With the mounting sleeve removed, gently slide the stereo unit out of the dashboard until the wiring harness and antenna cable are visible. Carefully unplug these connections by pressing the release buttons and pulling the connectors apart. Take care not to yank the wires forcefully, as it may damage the connectors or the wiring itself.

Once the power source is disconnected, proceed to remove the faceplate. Most Pioneer DEH S31BT models have a detachable faceplate that can be easily removed by pressing the release button or flipping the latch. Remove the faceplate and set it aside in a safe place to avoid any scratches or damage.
