To learn more troubleshooting techniques go to www.scannerdanner.com
Once again, this video covers why we need to learn proper troubleshooting techniques and to not be so reliant on manufacturer "flow charts". If you think your engine computer is bad, you must watch this video! Are there more tests that can be done to prove a computer is bad? What else should you check before computer replacement?
The following is a list of other tests and how to checks that were performed in this video:
1. How to test a 24x hall effect crank sensor
2. How to test sensor wiring integrity (both opens and shorts to ground)
3. How to test a hall effect cam sensor
4. How to test computer powers and grounds.
5. What is a shared reference circuit?
6. What do you do when you have low reference or power supply voltage to a hall effect?

1996 Jeep No Start Case Study Part I
An example of what we do at Rosedale Technical Institute in Pittsburgh, PA.
This is an all live work school, no make-believe car problems here! My
students and I used this oppurtunity to review certain concepts and testing
proceedures written in an Engine Performance/Troubleshooting book I wrote
for my class.
No Start Diagnostics Training at Rosedale Tech
Join me (Paul Danner aka ScannerDanner) and my class at Rosedale Technical
Institute while we troubleshoot a no start problem on a 1999 Subaru
Impreza. This was an unscripted video, everything was filmed live from
inside my classroom, with all of my students involved. For each new step in
the diagnostic process, I pause to explain what we are doing and why, so
this is a longer video than my normal upload, but I promise it will be
worth it. Even you veterans that are following me will learn some tips
along the way.
During my time teaching (14 years), I have developed a "field manual" to
help my students troubleshoot automotive electrical and electronic
problems. This book is available to you at www.scannerdanner.com as an
eBook. I also have lecture videos available to help you be part of my class
even more. With the purchase of the eBook, I will give you some of these
lecture videos for free.
Finally, if you are looking to go through auto technician training program,
I would love to have you as part of my class in person! We are located in
Pittsburgh Pa. For more information about Rosedale Technical Institute go

How to check for a jumped timing chain or belt
This video can be used to support Section 1 pages 17-23 in my ebook.
The method of timing verification shown in this video can be used on any
car. Even on old school, non-computer controlled systems. I am also showing
in this video how to properly align the timing chains on a 2003 Suzuki
Ford O2 Sensor Testing
For more on O2 sensor testing go to www.scannerdanner.com
In this video I address the following:
How to determine if the O2 sensor is reading correctly
How to perform a propane enrichment test
How to determine if an O2 sensor circuit has a bias voltage
How to reset KAM memory and why it it important to remember to clear it
How to quickly check for opens and shorts in an O2 signal circuit
Why is it important to unplug an O2 sensor during a PCM response test and
when to consider plugging it back in
How much amperage are you actually sending to the computer through your
