Ive got to pick up a scanner for my new GM motor going in my Jeep. What are some features to look for?
The biggest feature you need to look for is a live data stream.

Don't let the guys bust your balls. For the DIYr a scanner that reads live data is a great tool to have. Congrats on the new tool. I guess some people like to brag about their $12000 diagnostic scanners that they is debt up to their eyeballs to the truck man and put down those of us who get by with basic scanners that cost less than our vehicle. Have fun with your new tool and get used to using the live data stream. When I got my scanner (a land rover specific scanner that does ABS, SRS and programming) I drove around with it hooked up so I could play with it.
They are also a LOT more expensive than then the tools I started with.... The bottom line? Get a manual or go online with something like AllData to get some good trouble shooting info and start learning. The money you save might be your own.....
If you get stuck and can't figure something out, you still have the "take it to a pro" option
I have had AllData (aka SomeData) and I switched over to Mitchell On Demand back in 93. AllData has tried several times to get me back and sent me several free one month trials over the years. I like Mitchell much better. The only thing better about AllData is they now have color wiring diagrams. It's a hit or miss on the color but they are easier to read. The information in Mitchell is better IMO. I pay about 150 a month for it. I was paid up for a good while when I closed my shop. When it expires I'm on my own. Ive come to depend on it so much I doubt I'll be able to put brake pads on without it. lolI have seen AllData.com but never really heard much about it. Is it a good source of information? I looked through the site but its hard to tell on the sample car.
Ya I am going to have to figure out the live data thing then I will probably be playing with it alot, I wish I could have gotten a scanner that did ABS but the next model was alot more so I went with the 9180 figuring if I ever really needed to I could upgrade but I think this will keep me busy for a while.
I'm going to be doing all the reading I can. I have seen AllData.com but never really heard much about it. Is it a good source of information? I looked through the site but its hard to tell on the sample car.

To gain an understanding of engine controls, I recommend you get a copy (3rd edition or newer) of ADVANCED ENGINE PERFORMANCE DIAGNOSIS by James D. Halderman.
Read this book cover to cover and this will help you understand what the datastream is telling you about various sensors and actuators, etc.
Check online fleabay or other used online book source.
This book is money well spent.![]()
I use the AllData DIY site where you can buy a subscription to a single car for anywhere from 1 to 3 years. Once you have one or two bought, you can get a nice discount on additional cars. It is not as nice as Mitchell from what I hear but then again, it's not $150 a month either.....
It has always worked out well for me for everything that I have needed to find out on my cars. Everything from timing belts to sun visor removals to engine management systems and emission control systems were easy to access on line with a small laptop in the car.

man, im the exact opposite. i think mitchell ***** and all data is 100 times better. mitchell is difficult because they dont put the pictures inline with the text, and everything seems to be out of order in general. to mitchell's credit, they do have labor times and info on some 09/10 models that all data does not. if mitchell online was setup like their books, id have no issue. as their books are easy to read/follow. for me, wiring diagram in color or just black is not an issue. read a diagram the same none the less. just give me a key that lets me know color and im happy.
as for codes-- http://www.trouble-codes.com/ will help you out w/ what a code is. In addition, i know it is a vw/audi tool, but vag-com actually gives you a decent probable cause/solution to look for. http://wiki.ross-tech.com/wiki/index.php/Category:Fault_Codes the 1st number is vw/audi specific. second number will be the p-code, that is standardized across all makes/models. you will see some manufacture specific numbers dont have a p-code. thats why shops end up buying big dollar scan tools-- to know what those codes are. i dont think you will see p-codes listed untilpage 2 on the wiki site. still, a good source of info worth book marking.

So for AllData if I get a code will it show me things to look for that could possibly cause that code? Or is it just about how to tear things down? Thanks for all of the help on this, AllData is looking like a go for me.

Jeep I have been doing along of reading and it looks like the Service Manuals have what the values (when you do live data) are suppose to be so you can compare from there. But I am also interested in the difference between the 3rd and 4th edition.
Computerized engine controls by Delmar Pulishers is another good book I used in tech school. It is updated every 2 years to keep up with changes.
It all depends on how much and how deep you want to go in driveability repairs. If you don't go deep enough with the book knowledge, you will be no better than Joe shade tree: Parts changer, down the street.
Automotive Electricity and Electronics (tech One) by Al Santini is another good book we used for the electrical side.
As you can tell, I am a firm believer is gaining a solid foundation with book knowledge and applying it in repairs. Sadly, this seems to be missing in a lot of folks these days.
