Anyone have any suggestions for bidirectional scan tools? I'm finding I may need a means to control some solenoids to troubleshoot something on the wife's car. I was pleasantly surprised there are some inexpensive ones like Xtool, which seems like it would do the trick, but I'm wondering if they are universal enough that if they can control various solenoids or show live data, can they control all of the solenoids and read all the data? Looks like there's a variety of what they are capable of doing, like some can do TPMS and ABS bleeding.
