My truck has been chiming when I shut it off lately. Somtimes it dings twice and sometimes it dings 4 times. Anyone know why this is happening? I did a search and couldn't find anything that pertained to my problem. I did do a download for codes and I have none. I did get the ABS chime about 2 months ago, but I haven't got it since. Just wondering if anyone else has had this problem. Thanks.
