Electrical Troubleshooting 101
DO NOT, I repeat, DO NOT use a test light on a modern automobile. There HAVE been guys injured by airbags being setoff and electronic modules that have been destroyed from using them. They do not have enough internal resistance and essentially create a path to ground for a signal wire when probing with one.
As for the frequency testing, this would require a DVOM with frequency capabilility and doesn't necessitate a Tech II. Needless to say, that and the CAN troubleshooting are beyond "basic" troubleshooting and will not be a part of this discussion. Besides, if you can use a Tech II, you should already know how to use a DVOM and basic electrical troubleshooting. Kinda moot, huh?
