December 15, 2014 Martin from BC Canada takes on a deep dive into Diesel Exhaust Fluid and shares a perspective from the GM Service Information side.


Fun with Diesel Exhaust Fluid
Hi fellow TDFers. Recently, the specification values provided for Diesel Exhaust Fluid (DEF) in GM eSI were questioned, specifically as related to this thread by Paul Johnson...

December 3, 2014 Here is an interesting shop management challenge where Mark from Ontario, Canada shares a recent experience where his daughter's law school education paid off big time!

Daughter rescues dad
When my daughter was young, she once got stuck climbing a tree, so I helped her down. It was a simple thing for me, but to her I was a hero. As she grew older I would always help if she fell off her horse or locked her keys in her car. Now she is a grown up...

November 20, 2014 Ryan from BC Canada shares his findings on an interesting battle with ICP and leakage tests on a 2003 Ford F-550 6.0L. http://autop.ro/7YI


Low Injection Control Pressure (ICP) Making life interesting
I just wanted to share this on iATN as I feel that I have not contributed much lately. The above truck was brought to us from another shop that found a low ICP concern. The truck shut down on the customer and would not restart until it cooled off. After that i...

November 12, 2014 A California iATN member shares his experiment with in-cylinder pressure waveforms while manipulating valve lash. http://autop.ro/7YG


Vacuum and compression waveforms
Well I took a little time to experiment with vacuum and compression waveforms on my personal car. I used a homemade vacuum transducer using radio shack parts, a Pico pressure transducer and a PV-350 for the Verus screen shots. I was wondering if I could tell i...

October 27, 2014 Understanding alignment angle changes. David from Michigan provides a nice overview on alignment angles and how a change in value can influence vehicle handling. http://autop.ro/7YF

Understanding alignment angle changes
Hi all, Recently I was asked a question by a younger Tech that made me think. The thought was a realization, that there are probably many young Tech's out there, that don't understand how Caster angle affects Camber angle, when you steer a tire away from the...

October 14, 2014 P0420 and exhaust leak finding tips. Mike from Ohio has a few tips on locating leaks in an exhaust system that may lead to a DTC P0420. http://autop.ro/7YD


P0420 and exhaust leaks
Over the years I have learned many great things from the iATN gurus. The P0420 testing tactics have evolved over the years and have morphed into a pretty simple trouble tree. The Input of many people way smarter than myself seem to agree on a...

September 12, 2014 An early production error was discovered by James from Florida, who describes a recent experience with missing diagnostic info on a 2014 Chevrolet Caprice. http://autop.ro/7Pa

2014 Caprice P0455
I had a 2014 Caprice police special with a 6.0 come in today. The vehicle was ready for delivery but the MIL was on. Scanning with GDS2 showed a p0455 set current in the ECM. Checking data, there was no PID for fuel tank pressure available. Proceeding to EVAP

September 3, 2014 In this quarter's iATN Review we're highlighting discussions about diagnostic techniques used to solve for P0420s and exhaust leaks, programming anomalies on a 2012 Ford Focus, experimenting with vacuum and compression waveforms while manipulating valve lash on a Honda, how a shop owner's daughter saved the day, a positive story about ASE & Prometric, a diesel exhaust fluid analysis that includes an awesome pictorial, a Cummins 5.9L with coolant in the oil (that isn't from a leaking head gasket), and finally, a nice tip on how you can swap out the key blade when replacing fobs on late GM vehicles. http://autop.ro/7Mo

August 15, 2014 Overlook basic instructions at your own peril, especially with a Chrysler WIM/SKIM module replacement. http://autop.ro/7GI

chrysler wim/skim module(read inbox instructions or pay!)
hello fellow techs. got called out today for wim module programming. lucky for me the parts guy gave me a heads to read inbox instructions. ive done so many that i usually discard any papers that come in the box. appparently the new wim comes prepackaged with
