I used my aftermarket horn to scare some buzzards off the road in front of me and the low level gas light came on for a few seconds. I tried the horn again and the light came back on for a few seconds and then the check engine light came on for a couple of seconds. Tried it one more time, same result. Checked for error code and UO259 came. up. Called a friend who has a list of codes and he said there are 3 code #s with asterisk together with my number and it says can buss id. Is that something to do with fuses? Has anyone had this happen? I am thinking maybe the horn used too much power from the battery and the computer brain malfunctioned. Any thoughts will be appreciated. Oops, almost forgot: 2013 RT 22,700 miles.
