Hello, bought a 2020 corolla le a few years back, was used when i got it. But just recently started saying the device isnt supported while still working. And flashing the sos lights red and green. Doing some research i guess the dcm module is to blame but cant find much more. Tried unplugging the positive on the battery for about 30 minutes but will try both terminals, and longer. Heard theres a battery that can go bad but not sure how easy it is to get too. Also heard a service bulletin for a similar issue where it’s just needing an update, and lastly ive heard from many to disable the thing with the fuse but my fiance uses the microphone feature. Where should i go from here? About to disable it and jump the pins at this point.
