Howdy, check with local auto parts store if local to see if you can borrow a reader. With all these computer issues nowadays, especially with electronics, the alternator may or may not had been the issue. The auto parts place can also put the old alternator on their machine and verify it failed. If not, put the old one back on and see if issue(s) disappear, hope this helps.
