Hi,
I would like to purchase a good code reader that will work with my current and future vehicles. I am not a newbie and know about cars. (not as much as you guys however).
Anyway, I have been reading about the different functions and not sure what they mean. Some have "o2 tests" which I assume is an oxygen sensor test, some say "view enhanced live data" which I assume allows you to view sensor readings. Is there a manual or book somewhere that helps you "decode" what these sensor readings mean?
Some say "OEM level DTC information". I have no idea what that is. Some have "freeze frame data".
Most I was looking at in the Sears catalogue say "internet updateable". Does that mean if I bought one now it will work on a car I buy 5 years from now, etc?
I found one I like but not sure what exactly it does. It is the Innova
3160 Professional Scan Tool with ABS Diagnostics. The whole reason I like it is it works on ABS too. (Which my 1996 Chevy has had the light on for some time.) Although, it says it only works for domestic cars and trucks on the ABS side. (Why not Toyota, Honda, etc?)One last thing, I noticed language that says they can "turn off" the check engine and ABS light. If you turn the light off, will it just come back on the next time it detects a fault the next time you drive it or does it just stay off?
Anyway, I appreciate your help!
One more thing, What is the difference between these and the dealership computer. For example, the manual for my 2000 Dakota says somethign to the effect I cant adjust timing and if the engine runs rough after putting it togther to take it to the dealer to have the fuel control adjusted. Can any machine for a home mechanic do that? (I doubt it but thought I would ask.)
