I have done this and it works.
1. with pin C shorted to ground turn the key on ..... at this point the codes start flashing the DIC light
2. as the codes start flashing remove the short for 2 sec (I just count one, two)
3. then quickly short the pin again for 1 sec
4. then remove the short again for 2 sec
5. now short for 1 sec again
6. now remove short again for 2 sec
7. and finally short for 15 sec

The codes should clear. With some practice you can do the above without thinking. I created a push button switch for myself to do this. It is important in step 2 to remove the short AS the codes are flashing.
Good luck.
