I am learning about the engine and how it functions by monitoring it through EFILIVE. I know what a lot of the PID (parameter identifiers) mean but there are quite a few that deal with OBD functions that I would like to become more comfortable with.
Can anyone suggest a good publication I might read?
Thanks, nice site.

If you really want to learn all the EPA/SAE PIDS and the GM enhanced, books I use are :

1. SAE HS3000 OBD-II standard, buy it via SAE website

2. GM "Diagnosis of Code & no code faults with serial & PID data for cars from 93-2001"
This shows every PID each model and year has and what the PID ranges are

3. "OBD-II Diagnostic & repair for domestic vehicles"

Both are technical training books and published by Jendham.

That sounds like a great place to start. Thank you
The second book suggests that it only is valid to 2001. Have many pids changed in your opinion since mine is an '03 LS6.

There would be no real difference with a 03 over a 01 as far as power and drivetrain as to OBD-II PIDs.

EFILive has licensed the SAE generic PID descriptions from SAE and they are reprinted with permission as part of the EFILive scan tool. Just right click on a supported, generic PID and select "More info..." to see the description.

I agree with Team ZR1 about the Jendham books, they are useful.

One Jendham book that I would recommend is the
"General Motors Parameter Identification (PID) Data for Cars, SUV, Truck and Van Models from 1994-2003 Quick Reference Guide." Its number is GMHB0304.

However I cannot find any reference to that publication anymore so I do not know if it is still available.

I went to the Jendham site to try and fine one the books mentioned here. Their order pages are broken - their contact page is broken - and their email addresses all bounce back. Did they go out of business, or are they seriously confused about how to create websites...? Anyone know? I REALLY want to find more info about the extended sensor codes for my 02 Z06...

Mike, send me an email at emarkay@email.com. I also may be able to assist, (plus you are local! I live between Evansville and Louisville, a mile or so from I-64...) having been involved with some interesting OBDII issues for a few years myself...

Not specifically about PIDs but...

The shop manuals have some very good stuff about DTCs
including GM's recommended troubleshooting flow. They
are expensive but a highly worthwhile investment for any
person who wants to maintain or modify their own vehicle.
I have mine chock-full of Post-It bookmarks. Just the
electrical schematics alone are worth the price. Check
www.helminc.com

I bought another book that I pretty much dis-recommend.
"OBDII Diagnostic Secrets Revealed" is pretty lightweight,
it does cover other than GM vehicles. It is DiabloSport
(Predator type stuff) oriented to some extent. I did not
find any secrets in it despite the title. The price was out
of line with the value.

AllDataDIY is a web site that has basically the shop manuals
on line, plus some info on TSBs and such. If you don't care
for 20lb of paper manuals at $150 or so, the subscription
for this service is much more reasonable. Though I am old
school enough to strongly prefer a physical book and the
driveway is not a handy place to log in from.

You can find simple trouble code lists online, of course.
They may be a bit cryptic to be useful, other than as a
general guide to what's complaining. But worth grabbing
when you find such a list.
