The procedures shown in this
The procedures shown in this video will help you isolate the cause of a no start, no spark condition on a Toyota or Lexus system that uses an igniter built separately from the ignition coil. On 3 and 4 wire coil over plug systems, the igniter is actually built into the ignition coil. Similar procedures can be performed on those designs as well.
With any no spark condition, you need to determine if you have an input or output problem. If you can simulate the signals the engine computer uses to control the igniter, you can troubleshoot the problem area very quickly.
Test procedures shown:
- how to determine pull-up or pull-down circuitry
- how to read a wiring diagram
- how to "be the computer" and trigger the igniter to fire the coil
Tools used:
- Incandescent test light
- Digital Multi-Meter

On ScannerDanner Premium I will bring you right into my classroom at Rosedale Technical College. You will find page for page lectures taken right from my book as well as exclusive classroom type case studies. What is so special about these classroom case studies? I pull live problem vehicles directly into my classroom and we troubleshoot them in real time, using and applying the theory and testing procedures we learn during the classroom lectures. There is no better on-line training of how to troubleshoot automotive electrical and electronics systems anywhere!
