Does anyone know the hexadecimal instructions for actuation/test commands? I have an OBD2 non-GM scan tool and the list of commands but don't know what they mean.

gee... I don't even have my little IBM reference manual....

hex is a base 16... to convert from hex to decimal...... that's rather easy...

if I remember rightly... let's see!

0 = 0
1 = 1
2 = 2
3 = 3
4 = 4
5 = 5
6 = 6
7 = 7
8 = 8
9 = 9
10 = A
11 = B
12 = C
13 = D
14 = E
15 = F

Now, if you have a hex A4, it is then decimal 104... now, I don't have the decimal to ASCII conversion. sorry.

Appreciate the answer. I still need to know what the names of the tests are that go with the test codes.
