Why does everyone want to chop up things , by pass etc... The right fix could be cheaper then ruining your vehicle . Chopping up wiring harnesses . Their are by pass module , don't know how much they are . It may or may not fix the problem . Pulling the code and doing the diagnostics is still the best solution .
