There are two different options you are able to try in order to disable the beeping. The first one would be to go into the troubleshooting menu option on the Accessport and reset the KAM. If this doesn't stop the beeping you can simply go under the hood and unplug the symposer itself. Another option is to go to a Protuner and have them disable the sound symposer using the toggle menu under Advanced Parameters in Accesstuner Pro.
