I initially posted a question on one the existing threads, but one of the moderators suggested starting a new thread. A quick site search revealed very few hits for the Foxwell scanners. Perhaps this thread can become what folk’s experiences have been with the Foxwell scan tools and the Prius Prime. My original question was: Can the Foxwell NT520 Pro scan tool be used to change the constant beeping to a single beep when the shift lever is in reverse? Last night I verified my NT520 has the latest Toyota firmware package. This morning, when I connected it to the OBD2 port it would not auto-detect the Prime (mine is a 2021). After toggling through the various Prius model menus, I noted the latest Prius supported by the scanner is a 2016. For the heck of it, I selected that then tried, unsuccessfully, to find an option to change the reverse beep duration. I sent a support ticket to Foxwell asking why the Prime doesn’t show up on the tool. At this point I’m a bit irritated with them since I had bought the Toyota firmware package just last year and their site seems to imply they are constantly updating the firmware. I have used the NT520 on my 2005 Honda Pilot and 2014 Toyota Tacoma without any issues. I’ll post back Foxwell’s response once I hear back from them. Has anyone had any luck getting a Foxwell scan tool to auto-detect the Prime? What model Foxwell scan tool did you use? Were you able to change any of the “dealer only” customization options listed near the end of the owners manual? Are there other useful features of the scan tool which are specific to the Prime? Thanks for any insight you can offer.
