What scanner/ code reader do you like to start with? Looking at the CGSULIT SC301, not a top of the line unit but one that could do
some tests and work switches and solenoids, etc.
It seems to only access the ECM, that's quite limited if you want to diagnose other system issues. Do you consider wireless Bluetooth OBD2 scanners, like Bluedriver Pro and Xtool AD20 Pro, etc
