No problem, just trying to . . . .
see that you can read the DTCs.
Since you have the "CD", the codes are probably under the "CIS" system diagnostic section. I have the All-Data CD ROM: most everything is there but it's not easy to find.
Probably worth your time to browse through it. Let us know what you find.
