Zero point calibration for my 02 Lexus es 300

Hi I been having issues trying to fix my vsc and Trac off light, due to a zero point calibration on my 02 Lexus. This is my second time getting it since I've had this car,last time it didn't seem to be this hard to fix the problem with a paper clip. But I'm doing the same way that I did last time but it seems to be more of a headache this time around, if anyone has good extra tips to help the situation 0ut. Please don't hold back please and thanks
