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?

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
Toyota Echo No Communication Case Study
This is a 2001 Toyota Echo with a no communication problem. You guys have
been asking for one of these and I finally have a good one that goes beyond
a blown fuse for pin 16 of the DLC. Also covered in this video is comparing
the ohmmeter to a voltage drop test and which one is more accurate.
