Besides not working on anything but engine management, an OBDII scanner is just a fraction of what can be done with the proper tools.
of "not working on anything" but engine management, a scanner opens up a whole new world for the DIY'er who likes to wrench on his or her own vehicles. Very few people have the training, facilities and tools to perform a "true" diagnoses with the "proper tools."
I got my BR-3 scanner two days ago and it is absolutely wonderful
Can anyone say "wet blanket?"
