I am looking for a scan tool with the following features
Around $500 or less
Reads OBD II and shows code(s) and brief description of code(s) (eg. P0302 Cylinder 2 Misfire)
Will read both generic codes and manufacturer specific codes
Will show pending codes and history codes
Will show readiness of monitors
Will show freeze data when applicable
Not necessary to run manufacturer specific tests (eg. Evap tests)
Reads OBD I (with adapters where applicable)
Live stream data (Coolant temps, trans fluid temp, wheel speed sensor voltage (wave-forms), fuel trims etc.)
PC-link (to store data or make upgrades if available)
Oscilloscope capabilities (not necessary but would be helpful)
I will mostly need it for Honda/Acura, Toyota/Lexus/Scion, GM, Ford, Chrysler/Jeep. If it is necessary to purchase software upgrades for some makes I would still be interested. Any ideas?
Parts stores such as NAPA, Carquest, and the like typically have a range of scan tools from simple code readers to those designed for professional mechanics.
Until I got to the last two items on your list I was thinking of several tools that fit the bill. However I think those last two items will bounce you out of your $500 budget.
I second what Gary T said look at a NAPA store or ask your local tool guy what he has on the truck.
Are you a DIY-er or aspiring pro? If the former, you might just consider one of the laptop link cables. They’re far cheaper than a high-end scan tool but will do everything on your list except the OBD-I and the oscilloscope. But you’d be paying $50 instead of $500, so you could probably just pick up a cheap oscilloscope and individual OBD-I cables and still stay under budget. Heck, even if you don’t have a laptop, the scan programs are very basic and should work just fine with a sub-$300 netbook or an old used laptop.
But having a laptop in the car during drive tests is a little unwieldy and you have to worry about getting your laptop all greasy when you have it out in the garage.
I thought about getting a PC based scan tool but I definitely do not want to take my laptop to work and home everyday. Besides the battery is toast so I would not be able to take it on road tests. I had my eye on a craftsman scan tool that has everything I need except for the oscilloscope so I think I will be buying that instead. I know we have some skilled techs on the dope so I was wondering if they had any particular ones they preferred.
