Toyota Multiplex Diagnostics - Basic Overview Video
I'm Dave …, an instructor with … on Long Island, NY, and a part time instructor with WorldPac Technical Institute - WTI. I recently worked with the team at Diagnostic Network on a few informational videos and I'm here to introduce the first one covering Network Diagnostics utilizing the Toyota Techstream, TIS and the Picoscope.
As we all are aware, network communications is a critical part of making a modern day vehicle operate properly and safely. With a single malfunction on the network, multiple systems could be affected. I'll be covering a basic overview of the Toyota platform on this 2017 Camry. I mentioned earlier that we'll be using the Techstream and want to make sure that everyone knows that although we're using the dealer-level tool, you, as a service industry professionals have the ability to run the same software on your own device by subscribing to Techstream and utilizing Techstream Lite or a supported J-2534 interface. The powerful part to this tool is that it contains the diagnostics, service information, training, and reprogramming functions at a very low cost. If your shop is servicing Toyota, Lexus or Scion vehicles, I high recommend looking into acquiring a Techstream system by visiting techinfo.toyota.com. In the video you'll see reference to Quick Training Guides (QTG) within TIS which, in my opinion are invaluable. Here is an example of the type of material one would find as they accessed that information. You'll also see us testing pins 6 & 14 of can bus with the Picoscope. Here are a couple of screenshots showing a normal signal and a shorted CAN HI to ground as demonstrated in the video.
We hope you enjoy this video and I look forward to creating more content to support to Diagnostic Network. If you have any questions, please let me know.
I'd like to thank Diagnostic Network for helping me produce this video. If you have suggestions for future topics either email … or post a new message on DN using Diagnostic Network as the topic.
Thanks Dave for the info and the link! Ray
Thanks, Ray- I hope it was helpful. More to come!
Impressive production quality, well thought out and very informative. Thank you for sharing.
Thanks, Brin- This is the first in a series of videos we are working on. Any ideas for other content you might like to see?
I didn't want to "Let the Cat out of the Bag" on this Awesome Video. I was asked to go up to Long Island, NY as a consultant for this training video, I mentioned in a reply to a post how impressed I was in Scott Brown's effort to make this video the highest quality it could be. I've had the opportunity to produce and watch other training videos, But what I witnessed first hand on this project
First off,Woah,look at the mustache on this guy!! Thats new!! Second, fantastic work. Looking forward to more.
Great job! Everything nice and clear, good audio and bright visuals. This is what a good training video should be like!
I agree with you 100%, I witness how long it took to make sure the Training Video the quality it is. Believe me, There were A LOT of takes on each segment. I have VERY GOOD feelings about what The Diagnostic Network will become. These pictures attached show some of the "Behind the Scenes" work that went on.
Nice pictures, way to include one of my “good side” 🤓
Nicely done, Dave. I really like the way Toyota presents this topic. Scope testing is valuable. So is resistance testing. Thinking about how specific failures will impact the pattern, makes verification and isolation using the DVOM with confidence an easy task. I have a whole series of photos of resistance testing with and without a bus shorted to ground. That chart in the QTG611E page above
Jim, Thank you! I have been fortunate enough to work with Toyota very closely with the Toyota T-TEN program here at Suffolk and the material covered here is just a small part of what we cover with our T-TEN students. Toyota really goes above and beyond to make this information available to the independent repair sector at a very affordable price-point. When I teach classes for the independent
Thanks for the video and info, the timing couldn't have been better.
Hey James, Just wanted to commend you and your crew for owning a FIRST CLASS automotive repair business, I live right down the street in Southampton and pass your location about 3 times a week, I have heard NOTHING but good reviews from some of your clients.
This is a table I made based off the QT611E, to allow students or techs to make measurements and compare against the chart. I wanted to share to expand on this topic, I always liked this course's layout for resistance testing CAN. Of course in a spreadsheet it has its nice colors etc. (edit) Couldn't post the table or the file. Here is the
