I have a 2004clk320...can a launch cpt 123 work on my car to erase transmission codes?...i have a cheap obd2 scanner that erases codes but doesnt work on transmission codes(etc)

Long story short ...im trying to find the short in my electrical system and my transmission is good and so is my computer however there is a short somewhere so my car keeps going into limp mode and really need a scanner that can clear trans codes so i can still use car during the loooonnnnggg process of figuring out which wire is causing the short....so my question is would a launch crp 123 be able to work for my needs?
